I help SaaS leaders build trust, visibility, and inbound opportunity on LinkedIn | Writer on SaaS leadership, reputation building, and content that converts

I'm currently in a full-time SaaS leadership role while building Authority Signals, where I help other SaaS professionals grow their presence, sharpen their voice, and attract opportunity, without needing to go viral.

After more than a decade in SaaS, leading CS teams, building onboarding playbooks, and navigating the emotional pressure of being “the glue” - I realized something:

Great work doesn’t speak for itself.

Many of the most capable operators I know stay invisible online. They lead quietly, burn out privately, and get passed over for louder, flashier people.

I help them change that.

I work with SaaS leaders - especially in CS, GTM, and RevOps, to clarify their voice, tell the truth about their leadership journey, and build real visibility on LinkedIn.

I’m not a coach, and I’m not here to make you post every day.

Through my Leadership Narrative Sprint, I help mid-to-senior professionals reposition themselves around trust, clarity, and authority, not hustle or fluff.

I also write about the emotional reality of modern leadership:

Burnout from invisible labor

Boundaries in high-stakes roles

Building trust without performative branding

✅ 16K+ followers
✅ 1K+ newsletter subscribers
✅ Posts seen by over 1 million people

If you’re tired of doing great work in silence, and you want your next opportunity, client, or promotion to find you, I’d love to help.

90% of ML systems rely on fewer than 10 libraries

Choosing the right one matters more

Here are the Top Python libraries every ML engineer should know 👇

1️⃣ 𝗗𝗮𝘁𝗮 𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻𝘀 (𝗻𝗼𝗻-𝗻𝗲𝗴𝗼𝘁𝗶𝗮𝗯𝗹𝗲)

Before models, before AI, you need data control.

These are the base of everything:

𝗡𝘂𝗺𝗣𝘆
→ Numerical computing, arrays, math operations

𝗽𝗮𝗻𝗱𝗮𝘀
→ Data cleaning, analysis, CSV & SQL workflows

If you struggle here, every model later feels harder than it should.

-- -- -- 

2️⃣ 𝗖𝗹𝗮𝘀𝘀𝗶𝗰 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 (structured data still wins)

Most business problems are still tabular.

𝘀𝗰𝗶𝗸𝗶𝘁-𝗹𝗲𝗮𝗿𝗻
→ ML fundamentals, baselines, quick experiments

𝗫𝗚𝗕𝗼𝗼𝘀𝘁
→ High-accuracy models for structured / business data

This stack powers pricing models, churn prediction, fraud detection, and more.

-- -- -- 

3️⃣ 𝗗𝗲𝗲𝗽 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 (neural networks at scale)

When data grows and patterns get complex:

𝗣𝘆𝗧𝗼𝗿𝗰𝗵
→ Research and production deep learning

𝗧𝗲𝗻𝘀𝗼𝗿𝗙𝗹𝗼𝘄
→ Scalable, production-ready ML systems

-- -- -- 

4️⃣ 𝗡𝗟𝗣 & 𝗟𝗮𝗿𝗴𝗲 𝗠𝗼𝗱𝗲𝗹𝘀

Text data is everywhere now.

𝗧𝗿𝗮𝗻𝘀𝗳𝗼𝗿𝗺𝗲𝗿𝘀
→ LLMs, text generation, fine-tuning pretrained models

𝗚𝗲𝗻𝘀𝗶𝗺
→ Topic modeling, embeddings, document similarity

-- -- -- 

5️⃣ 𝗧𝗶𝗺𝗲 𝗦𝗲𝗿𝗶𝗲𝘀 & 𝗙𝗼𝗿𝗲𝗰𝗮𝘀𝘁𝗶𝗻𝗴

Often ignored. Always useful.

𝗣𝗿𝗼𝗽𝗵𝗲𝘁
→ Simple forecasting with clean APIs

𝗗𝗮𝗿𝘁𝘀
→ Forecasting and anomaly detection

-- -- -- 

6️⃣ 𝗣𝗿𝗼𝗯𝗮𝗯𝗶𝗹𝗶𝘀𝘁𝗶𝗰 𝗠𝗼𝗱𝗲𝗹𝗶𝗻𝗴

When uncertainty matters:

𝗣𝘆𝗠𝗖
→ Bayesian modeling and probabilistic inference

-- -- -- 

You don’t need to master all 10 today.

Start with the foundations.
Add tools as your problems get more complex.

Knowing which tool fits the problem already puts you ahead.

📌 Follow me for Data & ML content

Get started in Time Series with Pandas
(in just 10 minutes)

Here are a few simple but powerful tips 👇

𝟭. 𝗨𝘀𝗲 𝗶𝗻𝗱𝗲𝘅_𝗰𝗼𝗹 𝗮𝗻𝗱 𝗽𝗮𝗿𝘀𝗲_𝗱𝗮𝘁𝗲𝘀
When loading your CSV, set the date column as your index and convert it to a datetime type in one line:

pd.read_csv("BTC-USD_full_history.csv", index_col="Date", parse_dates=True)

→ That small trick saves tons of manual work later.
→ This tells Pandas to use date column as index for time series.

-- -- -- 

𝟮. 𝗦𝗹𝗶𝗰𝗲 𝗱𝗮𝘁𝗮 𝗯𝘆 𝘆𝗲𝗮𝗿 𝗶𝗻𝘀𝘁𝗮𝗻𝘁𝗹𝘆
With a datetime index, you can filter by date with one command:

btc_data.loc['2022']['Close'].plot()
btc_data.loc['2022-01']['Close'].plot()

→ Pandas understands almost any date format.
→ From just a year ('2022') to full timestamps with timezone or nanoseconds.

-- -- -- 

𝟯. 𝗨𝘀𝗲 𝗿𝗲𝘀𝗮𝗺𝗽𝗹𝗲() 𝗳𝗼𝗿 𝘁𝗿𝗲𝗻𝗱𝘀
Smooth noisy data using monthly or weekly averages:

btc_data['Close'].resample('M').mean().plot()
btc_data['Close'].resample('W').std().plot()

-- -- -- 

𝟰. 𝗖𝗼𝗺𝗽𝗮𝗿𝗲 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗲 𝘁𝗶𝗺𝗲 𝘀𝗲𝗿𝗶𝗲𝘀 𝗲𝗮𝘀𝗶𝗹𝘆

→ Stack data from multiple assets (like BTC and ETH) and plot subplots to compare performance over time.

-- -- -- 

It’s amazing how much you can do with Pandas alone.
No need for complex tools when exploring time series.

I made $70k on Upwork as a data scientist.
Not by luck. By rules I didn’t break.

Here are my 6 non-negotiables 👇

-- -- -- 

𝟭. 𝗚𝗲𝘁 𝘆𝗼𝘂𝗿 𝗳𝗶𝗿𝘀𝘁 𝟮–𝟯 𝗳𝗶𝘃𝗲-𝘀𝘁𝗮𝗿 𝗿𝗲𝘃𝗶𝗲𝘄𝘀 𝗳𝗮𝘀𝘁

I started with people I already trusted.
Friends. Family. Warm intros.
Social proof changes everything.

-- -- -- 

𝟮. 𝗟𝗲𝗮𝗿𝗻 𝗵𝗼𝘄 𝘁𝗼 𝘀𝗲𝗮𝗿𝗰𝗵 𝗼𝗻 𝗨𝗽𝘄𝗼𝗿𝗸 𝗽𝗿𝗼𝗽𝗲𝗿𝗹𝘆

Most people apply to bad jobs. I filtered hard:

- Same-day jobs
- Fewer proposals
- Verified clients
- $100k+ spent
- 4.3⭐+ rating

Bad jobs drain energy. Good jobs compound.

-- -- -- 

𝟯. 𝗙𝗶𝗹𝘁𝗲𝗿 𝗰𝗹𝗶𝗲𝗻𝘁𝘀, 𝗻𝗼𝘁 𝗷𝘂𝘀𝘁 𝗽𝗿𝗼𝗷𝗲𝗰𝘁𝘀

Skills matter less than people. I avoided:

- Vague requirements
- Unreal timelines
- “Quick task” language
- Budget pressure early

Good clients respect scope. Toxic ones don’t.

-- -- -- 

𝟰. 𝗪𝗿𝗶𝘁𝗲 𝗽𝗿𝗼𝗽𝗼𝘀𝗮𝗹𝘀 𝘁𝗵𝗮𝘁 𝗳𝗲𝗲𝗹 𝗵𝘂𝗺𝗮𝗻

No copy-paste. No essays.
Short. Clear. Specific. And often a Loom video.
Seeing your face builds trust faster than text.

-- -- -- 

𝟱. 𝗣𝗿𝗶𝗰𝗲 𝗯𝗮𝘀𝗲𝗱 𝗼𝗻 𝘃𝗮𝗹𝘂𝗲, 𝗻𝗼𝘁 𝗳𝗲𝗮𝗿

I raised rates as confidence grew.
Experience compounds. So should pricing.

-- -- -- 

𝟲. 𝗕𝘂𝗶𝗹𝗱 𝗮 𝗽𝗿𝗲𝘀𝗲𝗻𝗰𝗲 𝗼𝘂𝘁𝘀𝗶𝗱𝗲 𝗨𝗽𝘄𝗼𝗿𝗸 (𝗵𝘂𝗴𝗲 𝗯𝗼𝗻𝘂𝘀)

YouTube + LinkedIn helped clients trust me faster.
They could see how I think. Not just what I claim.

-- -- -- 

Upwork wasn’t the magic.
Systems were.

PS: What’s been your biggest struggle with freelancing so far?

80% of data science work fails after notebooks.

Engineering is the missing skill in 2026.

I worked on this with José Siles and the message is simple:
👉 Models don’t fail. Systems do

Here’s the assumption vs reality many data scientists face:

- Expectations: Notebooks are enough
- Reality: If it runs only locally, it’s not usable

- Expectations: Better models mean better results
- Reality: Bad data breaks even great models

- Expectations: Reproducibility is optional
- Reality: Versions and environments matter

- Expectations: Security comes later
- Reality: Access and data safety are part of the job

- Expectations: Accuracy is everything
- Reality: Cost, speed, and stability matter more

- Expectations: Complex beats simple
- Reality: Simple wins in real systems

- Expectations: Version only code
- Reality: Version data and models too

- Expectations: Docs are extra work
- Reality: Docs make work usable by others

- Expectations: Experiments create value
- Reality: Pipelines create value

- Expectations: Failures are rare
- Reality: Failures are normal, prepare for them

This isn’t about becoming a full engineer.

It’s about making your work real and trusted.

💬 Curious:

Which skill do you think matters most in real data roles?
Or which one did you learn the hard way?

Two months. 250M views. 700K comments.

One question: who should Steven Bartlett invite next?

I’ve always loved The Diary of a CEO.

It’s one of those podcasts that makes you think deeper, 
about business, people, and purpose.

So I decided to turn my curiosity into a real AI project.

A few months ago, I built an AI system that analysed every episode of The Diary of a CEO in 2025, every topic, every guest, every comment.

Here’s what it did:

- Ran 𝘁𝘄𝗼 𝘁𝘆𝗽𝗲𝘀 𝗼𝗳 𝗮𝗻𝗮𝗹𝘆𝘁𝗶𝗰𝘀:
 - 𝗧𝗼𝗽-𝗳𝘂𝗻𝗻𝗲𝗹: measuring episode performance through views, likes, and engagement metrics. Given them different weights.
 - 𝗖𝗼𝗺𝗺𝗲𝗻𝘁 𝗮𝗻𝗮𝗹𝘆𝘀𝗶𝘀: using NLP, LLMs and SLMs to understand audience sentiment at scale
- Combined both layers to see what drives real engagement beyond the surface

This project wasn’t just about insights; it was about "learning".

I wanted to:

- Build a full 𝗲𝗻𝗱-𝘁𝗼-𝗲𝗻𝗱 𝗔𝗜 𝘀𝘆𝘀𝘁𝗲𝗺 from scratch
- Handle real, messy text data at scale (emojis, sarcasm…)
- Use AWS GPU servers for training and Streamlit for deployment
- Actually ship something meaningful

It reminded me why I love data.

You don’t need to do random tutorials or fake datasets.

You can take something you’re genuinely passionate about, podcasts, football, fitness and turn it into a real AI project that teaches you 10x more.

𝗧𝗵𝗶𝘀 𝗼𝗻𝗲 𝘁𝗼𝗼𝗸:

💻 Python, NLP, LLMs, SLMs
☁️ AWS for compute
🕓 2 months (nights + weekends)
💰 ~$100 total cost

Based on the analytics, the top 5 topics were 𝗧𝗲𝗰𝗵, 𝗣𝗼𝗹𝗶𝘁𝗶𝗰𝘀, 𝗥𝗲𝗹𝗶𝗴𝗶𝗼𝗻, 𝗣𝗲𝗿𝘀𝗼𝗻𝗮𝗹 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁, 𝗮𝗻𝗱 𝗙𝗶𝗻𝗮𝗻𝗰𝗲,

And the most requested guest by far was 𝗘𝗹𝗼𝗻 𝗠𝘂𝘀𝗸.

Who knows… 

With more time and resources, I could make this even better.

PS: Want to see a detailed breakdown? Let me know ⤵️

STOP chasing certifications.
They might be hurting your career.

Do you think visiting every football stadium in Europe
makes you a professional football player? ⚽

Same thing here 👇
• AWS certs
• Azure certs
• GCP certs

If you never build real projects,
you’re just collecting tickets, not skills.

Certifications support experience.
They don’t replace it.

Be honest:
What helped you more, certifications or real projects?

(Hot takes welcome 👀)

Everyone wants to be an AI Engineer.
But not many want to master the foundations first.

Miguel Otero Pedrido a Senior ML Engineer, recently told me:
“AI engineering becomes easy when your MLE foundations are strong.”

Still, most people skip the basics like:
→ CI/CD pipelines
→ Feature engineering
→ Model experimentation & tracking
→ Deployment, monitoring & observability
→ Reproducibility (Docker, version control, etc.)

Then they open n8n,
build a few workflows,
and call themselves AI engineers.

I’m not here to tell anyone what to do.
But over the years, I’ve learned to tune out the hype and stick to my plan.

The AI engineers you admire on LinkedIn?

Most have 5+ years of experience in data science and ML engineering.
They didn’t shift into AI overnight.

Stop following the hype.
Start building your career the right way.
