I build production-ready systems for data-driven products
I build useful products, especially when backend, data, UI and production need to come together without a huge team around them.
I care more about readable systems, restrained interfaces and honest write-ups than polished landing-page promises.
What I Build
The parts I actually touch when I ship a product end to end.
Backend
Build scalable backend systems with Spring Boot, reactive pipelines, and microservices.
Frontend
Design real-time data flows, deploy on Kubernetes, and automate CI/CD pipelines.
Databases
Deliver production-ready frontends with Vue and Angular, from UI design to release.
Current Project
The thing taking most of my time right now.
Real Estate Analytics Platform
In ProductionProblem
Buying a property from an average price per square meter is still too shaky for a real decision.
Solution
I combine market data, deterministic rules and an AI layer to produce analysis that stays fast to read but easy to justify.
Output
A decision-support report you can use in seconds, with the assumptions still visible.
It is the kind of product I like building: full stack, concrete trade-offs, short iterations, and no fake polish hiding the hard parts.

Claude 4.5 et les fondamentaux : quand l'IA ne challenge pas le design
J'ai demandé à Claude 4.5 de m'assister sur une app. Plusieurs jours après, je découvre un choix de conception bloquant. Retour d'expérience.
