About Paul

Currently in my final year of engineering school in Bioinformatics, I combine scientific rigor with web product culture. I don't just 'code interfaces': I build Full-stack Type-safe architectures designed for performance and maintainability.

My specialty?
The T3 Stack. I exclusively develop with tools that guarantee maximum robustness from backend to frontend.

What I bring to your team:
Mastery of Next.js (App Router): Development of performant React components and optimized rendering management (SSR/ISR).

Data Architecture with Prisma: Modeling of complex database schemas and mastered migrations.

Type-safe Communication via tRPC: Zero compromise on typing. Intensive use of Zod for data validation.

Engineering Rigor: My background in bioinformatics has accustomed me to handling critical data volumes where errors are not an option.

Why work with me?
I offer a bandwidth of 10 to 15 hours per week, ideal for startups or agencies needing autonomous technical support for specific sprints or background tasks (refactoring, new features, API implementation).

My workflow: Git (Clean commits), CI/CD, clear documentation, and self-explanatory code.
