Today’s AI revolution isn’t an AI revolution at all. It’s a UX revolution.

If you used Netflix or Google products 10 years ago, you interacted with AI. But you weren’t supposed to know it. 

The predominant design philosophy of the time centered on hiding the AI but delivering magical moments like tailored movie recommendations and autocompleted email copy. GenAI changed all that.

Now, the AI systems are put directly into the hands of the end users. Everyone can be the builder; anyone can create a custom graphic, website, or entire app just about instantly. 

ChatGPT did a great job with creating a chat interface, but we haven’t even cracked the surface on the kinds of user interfaces that are possible. I can’t wait to see how this evolves. 

If you’re building interesting GenAI UX, tell me about it in the comments! 

I also expand on these topics in Samuel Durand's documentary about the future of work. You can check out a clip below, or watch the full documentary here: https://lnkd.in/eZfvEmT9

Writes on ML/LLM Ops 🎨 | Follow me (4,8 K+) 🔔

I help AI startups go from promising to unstoppable.

I also write about it, my book Agentic Graph RAG (O'Reilly, 2026) is the practical blueprint for building AI systems that combine retrieval, reasoning, and autonomous decision-making at enterprise scale.

https://www.oreilly.com/library/view/agentic-graph-rag/9798341623163/

My career has been a journey across both sides of the table: building AI products as a CTO, transforming legacy systems as a Field CTO for enterprises and government, and now at AWS, helping the most exciting GenAI startups scale across Europe and the US.

I've shipped GenAI platforms, deployed MLOps pipelines serving millions, advised L'Oréal on AI-for-BI transformation, and lectured at Oxford on the intersection of LLMs and graphs. But what gets me out of bed is working with founders who are solving hard problems with bold ideas.

At AWS, I connect high-potential startups with the resources, partnerships, and enterprise pathways they need to grow. Before that, I was in the trenches, building, breaking, and shipping.

If you're a founder, VC, or enterprise leader thinking about GenAI, agentic systems, or knowledge graphs, I'd love to chat.

Chief AI Officer & Decision scientist

Management in AI Projects and Engineering Teams:
In my managerial role, I oversee AI projects and lead teams of engineers in crafting cutting-edge solutions. My focus is on driving strategic initiatives, ensuring projects are aligned with organizational goals, and fostering a culture of innovation and excellence. I take a hands-on approach to problem-solving and mentorship, ensuring that both projects and people reach their fullest potential.

Development in LLM/ML Ops:
My development expertise lies in the specialized domains of Large Language Models Operations (LLM Ops) and Machine Learning Operations (ML Ops). I am responsible for streamlining machine learning workflows from development to deployment. My work enables organizations to not only adopt but excel in leveraging machine learning technologies, facilitating continuous learning and adaptability across the board.

Marketing and Strategic Partnerships:
In the realm of marketing, I focus on building and nurturing strategic partnerships. My efforts are geared towards creating synergies with like-minded organizations and industry leaders. By forming valuable partnerships, I amplify brand visibility, foster innovation, and open doors to new business opportunities. The result is a win-win situation for all stakeholders involved, enhancing both market reach and impact.

Three engineers at OpenAI shipped 1 million lines of code without writing a single line themselves. 🔺

Separately, a 7B parameter model beat GPT-4o by 41.9% on multi-step agent tasks.

Both teams discovered the same principle: the environment determines the agent's ceiling, not the model.

@Ryan Lopopolo's Harness team ran Codex agents for 5 months. 1,500 PRs merged. 3.5 PRs per engineer per day. The constraint was deliberate: zero human code. When an agent failed, the fix was never "try harder." The question was always: what capability is missing, and how do we make it legible?

They built progressive disclosure architectures where AGENTS.md stays under 100 lines and points to structured docs. Per-worktree isolation with full observability stacks torn down after each task. Background garbage collection agents scanning for pattern drift on a regular cadence. Agents reviewing other agents' PRs, humans optional.

SkillRL (Xia et al., 2026) attacked the same problem from the opposite direction. Instead of engineering the environment upfront, they let agents distill their own experiences into reusable skills. Raw trajectory storage caused a 25.2% performance drop. Agents that memorized their past got worse. Agents that abstracted their past into structured skills (name, principle, whentoapply) improved continuously. The library grew from 55 to 100 skills during training through recursive co-evolution with GRPO reinforcement learning.

Ashpreet B.  Bedi's open-source Dash framework proved the same pattern works without fine-tuning at all: context plus memory beats retraining. OpenAI's own Kepler data agent runs on the same principle across 3,500 users and 600 petabytes.

Both approaches converge on the same two bets: structured knowledge beats raw data, and mechanical enforcement beats advisory guidelines. Their systems co-evolve rather than ship-and-forget.

The gap neither has solved: governance. SkillRL uses flat semantic retrieval with no conflict detection between skills. Harness encodes golden principles manually. Neither tracks provenance, dependency ordering, or compositional constraints. Skills form dependency graphs with conflict edges, composition paths, and provenance chains. The governance layer for self-improving agents is a graph structure.

The engineer's job has shifted. Write zero code. Build the environment. Let the graph enforce the rules.

And not only engineers…
