About Me

Mickael Gomes

Earth, 37 years old and many more to go

Senior engineer, ten years full-stack, who builds production LLM/agent systems and makes them measurable and safe to operate: threat modelling, evaluation harnesses, prompt-injection testing and red-teaming, validated outputs, bounded retries, cost tracking. 2 AI products shipped for clients, 3 personal LLM systems built end-to-end in TypeScript and Python. 9+ years remote in US, UK and EU teams, from AI startups to ENGIE: I scope with founders and CTOs and ship fast (production MVP in 14 days). Recent: a full-stack B2B platform with an LLM agent producing its end output, its evaluation and safety harness, and 8 SDKs (stealth, current); a consumer AI video MVP live in 14 days (Mini Studio); the 4-year run on Football Index's trading platform, frontend team grown from 0 to 10. Own products: JobLens AI on the Chrome Web Store, 305 installs in 6 months, ~30 weekly users, eval harness over 49 labelled fixtures; an Etsy listing engine with RAG in daily use; SDS Sentinel, packaged, pre-launch. Stack: TypeScript, JavaScript, React, Next.js, Node.js, Python; Go and PHP behind it.

EDUCATION

From Biology to Computer Sciences

Beijing Jiaotong University

To test my adaptation skills, I decided to go study in China because it was the destination with the most cultural differences compared to Europe. That's how I happened to study in Beijing Jiaotong University. During that year I had the opportunity to work on many small projects (IoT, mobile app, etc...) and a small tower defense game using unity 3D. On that last project I decided to take care of the creep design by extracting the 'Warcraft 3' game units models and applying them to our games units.

EPITECH - Masters Degree: Computer Sciences

I knew that the best way to learn computer sciences effectively would be through practice. EPITECH being a project oriented school I knew it would fit my requirements. While I was there I had the opportunity to work on various projects using a different sets of technology. Those 5 years spent practicing and working in 5-6 people teams allowed me to gain the experience needed to create and lead my own team to work on our graduation project 'Orphée' over two years.

Lycée Marie-Curie - Degree: Biology

After obtaining my High School Diploma with mention, I wanted to keep pursuing my studies in this area by obtaining a BTS (Superior Technician Diploma) in two years. During those two years I did two internships in a laboratory and an hospital that made me realize that the job I was aiming at didn't have a future since this industry is getting more and more mechanized. So after obtaining my BTS, I decided to go for computer sciences which I had discovered a few months before and enjoyed a lot.

GEAR

Set up

I'm OS Agnostic

Three laptops, three operating systems, zero loyalty: a MacBook Pro M1 (macOS), a Dell XPS 14 (Windows), and an older MacBook Pro i9 I wiped to run Omarchy — DHH's Arch + Hyprland Linux build. I've been coding across all three for years, so I'm equally happy praising or roasting any camp when the memes call for it.

Backing them up: a huuuuuuuuuuuuuuge 49" Dell screen which is a plus for productivity, a portable screen for when I work outside, and both a recent and an old smartphone for testing the responsiveness of the sites I work on.
