About Antonin

Full stack developer, I design end-to-end web applications — from APIs and server-side business logic to the interfaces that make them useful. My main playground: Node.js and TypeScript, with PostgreSQL for data.
What sets me apart is the care taken with the code: clean architecture, SOLID principles, DRY/KISS. Not out of dogmatism, but because clear, well-structured code is cheaper to evolve — and reads without wincing.
I prefer a simple, readable first draft, even if it means refactoring later, rather than over-architecting from the start.
I am comfortable with demanding business logic: data modeling, historization, diff calculation, exports, structuring existing projects. I am also training in AI-oriented development.
Currently employed, I am available for occasional parallel missions. Need reliable and autonomous support? Write to me.
