I'm a career coach and entrepreneur. Previously, I was a Senior Data Scientist at Amazon with 7 years of experience in data science & ML. 

When I started my career, I felt lost. I struggled to meet expectations and feared I wasn't good enough. I had to figure out how to navigate my career and advocate for myself. Eventually, I got promoted to a senior data scientist at Amazon, leading high-impact projects and mentoring data scientists and MLEs. My career advice has been featured on Business Insider, Amazon Science Blog, and VentureBeat.

In my coaching program, I help data science/ML professionals advance their careers and future-proof themselves without the burnout.

Last night felt surreal. I went to The Monkey King (猴王悟空) opera with Chip Huyen and Khailee Ng — three friends from China, Vietnam, and Malaysia, all connected by the same childhood memory.

For anyone who didn't grow up with him: The Monkey King is a rebellious, brilliant, rule-breaking monkey who went on a journey to retrieve Buddhist scriptures. One of the most iconic characters in Chinese culture.

Seeing his story performed in English and Mandarin at the San Francisco Opera was magical.

Thank you to the NVIDIA team for the invitation — and especially to Jensen Huang and his family, who served as Honorary Chairs of this world premiere. They partnered with SF Opera to bring this iconic Asian story to a global stage.

We got there early to join a pre-show interview with Jensen, someone asked him “what do you like the most about the Monkey King?” He smiled and said: "The monkey is a little naughty."

That’s right. The Monkey King isn’t a traditional hero. He's fearless, resiliant, yet mischievous. He can fight anyone, outsmart demons, and endure the darkest challenges — he was buried under a mountain for 500 years.

Yet he emerges still playful, still pure at heart. 

He has seen the weight of the world, but somehow keeps his childlike innocence. I wonder if Jensen sees a bit of his own resilience and playful nature in Monkey King's story.

The show was a beautiful blend of Western Opera, Chinese Opera, acrobatics, and immersive light design. The New York Times called it "a jaw-dropping feat of music theater. Worth looking into if you're in the Bay Area!

I hope more tech leaders continue to support the arts in this city — bringing people together in real life.

Helping tech leaders and senior ICs gain visibility, build optionality, and achieve their versions of success | Ex-Amazon Sr. Data Scientist

Someone just asked me: "If layoffs can happen anytime, does getting a promotion still matter?"
It depends ⤵

If you're already at that level and learning to advocate for yourself, influence others, and navigate politics: yes. Go get what you deserve. Those skills transfer everywhere.

But if chasing the title is a distraction, if there's another team where you'd learn more even if it delays the promotion: skip it.

The real questions: 
1. Am I building skills that compound? 
2. How much value does this title actually add to my resume and personal brand?

Your technical skills might be obsolete in 3 years. Your ability to influence stakeholders, lead cross-functional teams, and advocate for your impact compounds forever.

Either way, stay engaged. Build the relationships. Learn from every project.

The goal isn't to collect titles. It's to build the skills & your personal brand to make you valuable in any market.

I believe 3 skills are essential to win in the next 5 years. I break them down in my "Contractor Economy Starter Kit" article. Get full access: https://lnkd.in/exDzawDb

Five things I'm grateful for in 2025:

1. My digital nomad journey in Asia & US

After living in 5 cities in Asia, I finally lived in NYC for 5 months as my last stop. I'm grateful for the new friends I made along the way. Except this time, I made friends differently. 

I used to go to a lot of meetups when visiting a new city, but this time, I only relied on friends' referrals. I asked them who they think I should meet. The connection is so much deeper when it's vetted by people you trust. Quality > Quantity.

2. My teachers outside of Tech 

I haven’t written a line of code in two years. Instead, I treated coaching like a second Master’s degree. I realized giving people a strategy isn’t enough. You have to work on their emotion. 

Because emotion is what actually drives decisions. To the executive coaches and healers who taught me how to help people overcome fear and self-doubt: Thank you. This work is more rewarding than any code I’ve ever shipped.

3. The Client Wins 

Nothing beats this. I watched clients transform: 
→ From terrified of presenting to winning executive buy-in. 
→ From stalled careers to securing Senior promotions. 
→ From "scared to post" to landing speaking invites at conferences. 
→ From undercharging to launching their dream products. 

I always believe in my frameworks, but seeing real results motivates me to share this with more people!

4. The Community - You

From the quiet lurkers to those who send heartfelt emails and LinkedIn comments — thank you. I read every response. Even if we haven't met, reading your stories feels like hearing from a friend. You fill my "jar of love" and keep me going. 🤎

5. Time with Family (The most important one) 

I got to see my grandpa before he passed away this year. That moment clarified everything. It reminded me exactly why I chose this path of freedom. I didn’t leave the corporate ladder just to travel. I left so I could be present for the moments that actually matter.

All of these things led me here. And I want to help you find that same freedom and fulfillment for 2026.

So, for Thanksgiving, I am doing an "All-In" special offer as a gift to you. I am unlocking ALL my course materials (20+ hours) + a 1-on-1 Strategy Call with me to map out your next career move.

Whether you want to climb the corporate ladder or build your optionality, this bundle covers the exact frameworks I used to get promoted in Big Tech and build a successful personal brand. They are from my $2,000+ courses and are now only $199 for Thanksgiving week.

How top 1% data scientists communicate with stakeholders - a checklist I wish I had 8 years ago (pay attention to the last one):

We are officially in the "wrapping up" season. How you communicate your wins now determines the projects (and promotion) you get in 2026. 

Here are 3 things I learned from the top 1% data scientists:

1. Put it in a "what if" scenario using business metrics 

❌ Don't say, "The model has 85% accuracy in predicting customer churn" 

✅ Say "If we implement this model, we could prevent losing ~850 out of every 1000 at-risk customers, saving approximately $1.2M in annual revenue based on our average customer lifetime value."

2. Use English terms instead of jargon 

❌ Don't say, "We used XGBoost with SHAP values for feature importance." 

✅ Say "We built a system that learns from past customer behavior, and it shows us the top 3 warning signs before a customer leaves - price sensitivity, declining usage, and support tickets."

3. Help your stakeholders explain it to their stakeholders 

❌ Don't assume your job is done when you get direct stakeholder buy-in. 

✅ Your mission: Make your stakeholders look like heroes to their bosses! Package your insights into ready-to-use slides with compelling narratives. Remember: Your work's success depends not just on your direct stakeholder's approval but on their ability to champion it up the chain.

If you want to drive impact and get promoted in 2026, you have to stop thinking like an "executor" and start thinking like a "partner."

You need to know: 
→ How to influence stakeholders without authority. 
→ How to present to Executives (so they actually listen). 
→ How to make your impact visible to the people who control your budget.

I have helped data scientists/MLEs get promoted and receive excellent performance reviews by teaching them the "Corporate Mastery" frameworks that nobody teaches in school.

For Thanksgiving, I am unlocking my entire playbook. I’ve put ALL my courses into one "All-In" Bundle. It includes:
1. Senior Promotion Strategies: How to get promoted without burning out.
2. Stakeholder Management: How to get buy-in for your ideas.
3. Executive Presentation: Turning "shy presenter" into "confident speaker."
4. DS/ML Project Strategies: How to identify and deliver high-impact projects
5. LinkedIn Personal Branding: Attract high-quality career opportunities 

Plus, you get a 45-minute 1-on-1 Strategy Call with me. We will sit down and map out exactly how you get to the next level in 2026.

Total Value: $2,000+, previously only available through group coaching.
Thanksgiving Offer: $199 for 6 weeks. You'll have plenty of time to binge-watch the 20 hours of on-demand courses during the holidays.

You should have an "Independent Contractor Mindset" even if you have a full-time job today.
Some people think that means 3 things: 

→ Do the bare minimum 
→ Stop caring about your coworkers
→ Ignore work relationships, just ship technical work

That's the OPPOSITE of what I mean.

The misconception is to think that Contractor Mindset means protecting yourself by disengaging.

Actually, the best contractors do exactly what the best employees do: 
→ They maintain deep relationships with clients 
→ They understand the client's broader business needs 
→ They become trusted advisors, not just executors 
→ They get bigger contracts, more equity, strategic influence

So, what's the difference?
Here's what the Contractor Mindset looks like in practice:

→ You're fully engaged in your current role AND you're keeping your LinkedIn updated and building your personal brand.
→ You're pursuing that promotion AND you're learning stakeholder management that works anywhere.
→ You're committed to your team's success AND you're protecting time for family, friends, and side projects.

The Contractor Mindset isn't about checking out. 

It's about staying engaged, gaining transferable skills, and building optionality outside your job.

Your AI agents can't reason about what they can't structurally represent. ⭕ 

The gap between demos and deployable agents comes down to one thing: knowledge representation strategy.

Here's when knowledge graphs become non-negotiable for agentic systems:

🔗 Multi-hop inference is core to your reasoning tasks

Vector embeddings excel at semantic similarity but collapse on relationship queries. When your agent needs to traverse "Service → DEPENDS_ON → Database → PROTECTED_BY → SecurityGroup" to assess blast radius, you need graph topology. Property graphs give you O(1) relationship traversal. Document stores force you to reconstruct connections at query time.

⚡ You're hitting the relational complexity threshold

The 30-table heuristic is real. Beyond this, JOIN complexity explodes exponentially. More critically: when understanding connections requires traversing 3+ relationship types simultaneously, relational schema optimization becomes the bottleneck. Graph databases are optimized for exactly this access pattern.

🧠 Your agents must handle temporal reasoning and contradictory perspectives

Event-centric schema patterns capture causality. Multi-perspective patterns represent conflicting data sources with confidence scores and provenance. Try modeling "Terraform says X, AWS API says Y, confidence scores differ" in a relational schema without creating a maintenance nightmare.

🔄 Entity resolution across fragmented systems is blocking coherence

When the same entity appears as "Bob Jones" in CRM, "Robert Smith Jr" in fraud detection, and "R.J. Smith" in compliance, your agent needs evidence-based resolution using relationship patterns and contextual validation. Graph neighborhoods provide the evidence structure for identity inference.

⚙️ The three-graph architecture matters for production

Separate domain graph (trusted structured data), lexical graph (unstructured source text), and subject graph (LLM extractions). Entity resolution creates CORRESPONDS_TO edges between them. This prevents extraction artifacts from polluting canonical knowledge while maintaining full provenance.

❌ Skip graphs when:

Simple retrieval suffices, no multi-hop reasoning required, or relationship density is low. RAG with vector search handles these cases at 1/10th the infrastructure complexity.

The technical reality: RDF gives you formal reasoning semantics but slower performance. Property graphs give you traversal speed but require explicit inference logic. Hypergraphs handle n-ary relationships elegantly but lack mature tooling.

Choose based on your reasoning requirements, not architectural trends.

What's your biggest challenge in getting LLMs to reason over complex, interconnected enterprise data?

Senior AI/ML Strategist Startups @AWS | O’Reilly Author | Business Angel

Your LLM based agent can't reason about what it can't traverse. ❌ 

After analyzing production agentic systems at scale, I've identified why most AI agents fail: they're built on vector embeddings and relational schemas that fragment knowledge into isolated records.

The agents that actually work? They're built on graph-based knowledge models that encode relationships as first-class primitives.

🏗️ Architecture pattern that's winning: The three-graph model

Separate your knowledge graphs by epistemic confidence:

Domain Graph: Canonical entities post-entity-resolution. Stable identifiers, validated relationships, single source of truth.

Subject Graph: LLM extractions with explicit uncertainty. Confidence scores, model versions, extraction metadata preserved.

Lexical Graph: Original unstructured sources. Complete provenance, immutable text chunks, enables RAG retrieval.

The killer feature? CORRESPONDS_TO relationships link Subject → Domain only after entity resolution validates the match. Your agent knows what's certain vs. extracted.

⚙️ The technical tradeoff matrix I'm using:

Property Graphs (Neptune, Neo4j): Fast traversals, intuitive semantics, but inference requires explicit coding

RDF + OWL: Native reasoning via formal logic, but 3-5x performance hit and complexity overhead

Hypergraphs: Natural n-ary relations (prescription linking doctor, patient, medication, dosage simultaneously), but immature tooling

Most production systems? Hybrid LPG for performance + RDF layer for reasoning tasks.

🎯 Implementation pattern: Selective vectorization + ontology-driven traversal

Don't vectorize everything. Curate your vector search space:

Index: Service names, error signatures, entity anchors

Exclude: Full configs, log streams, operational noise

Vector search handles ambiguous queries. Ontological annotations drive precise graph traversal for contextualization.

Result: Semantic flexibility + structural reliability.

📐 Entity resolution is your foundation

Evidence-based matching with Jaro-Winkler similarity + context validation. Not LLM guessing.

Explainable: "92% match because name=87%, address=100%, phone=95%"

This generates the stable node identities everything else depends on.

The companies shipping reliable agents aren't prompt engineering harder. They're building knowledge architectures that make invalid reasoning paths literally untraversable.

AI agents are economically broken at scale without caching ❌ 

A single user goal triggers 5-10 LLM calls in loops. At 10K daily conversations, you're burning $547K/year on a single workflow pattern.

The obvious fix? Semantic caching with vector embeddings.

The problem? It fails catastrophically for agents.

🔴 Why Semantic Caching Breaks:

Agents execute context-dependent reasoning chains. Each step builds on previous steps.

"Analyze Tesla's Q3 performance" vs "Analyze Tesla's stock price"

Cosine distance: 0.28 → Cache hit 

Actual equivalence: False

Your agent retrieves a financial analysis plan when the user wanted technical specs. 

The entire workflow executes the wrong reasoning path.

Tune your threshold tighter → 5% hit rate (still burning $520K) Tune it looser → 65% hit rate but 40% false positives

The F1 optimization doesn't solve context drift.

🔧 The Architecture That Works:

Hybrid Cache = Vector Speed + Graph Intelligence

Layer 1: Vector DB for fuzzy matching (~30% of redundant queries) 

Layer 2: Knowledge Graph storing reasoning structures, not text
Explicit entity disambiguation (Apple fruit ≠ Apple stock)
Multi-hop traversal for validating context alignment 

Layer 3: Validation gate before serving cached plans

🎯 The Critical Shift: Granularity

Don't cache full responses. Cache atomic sub-queries.
"Compare platforms" decomposes into:
FetchFeatures(Platform A)
FetchPricing(Platform A)
FetchFeatures(Platform B)
CompareAttributes(A, B)

These canonical sub-tasks repeat at 40-70% rates vs 5-15% for full workflows.

The graph stores execution plan templates. 
Vector search finds intent. 

Graph traversal validates the reasoning path applies to current context.

📊 Production Results:

Hit rate: 65% (vs 8% with semantic-only)
Precision: 95% (vs 40% with loose thresholds)
Cost: $547K → $191K annually (65% reduction)
Latency: 60% faster (cold → hot state)

Graph adds 20ms per query, but prevents false positives that would cost 2000ms+ in LLM calls or failed workflows

The Mental Model:

Traditional cache: "Have I seen this text?" 
Semantic cache: "Have I seen something similar?" 
Agentic cache: "Do I know how to solve this class of problem?"

You're not storing what agents said. 
You're storing how agents think.

The cache evolves from a lookup table to a reasoning substrate, the agent's long-term memory of validated strategies.

Agentic needs graphs. 

At scale, the hybrid architecture : the difference between agents that burn capital and agents that generate ROI.
