Yoan Partouche

Full-stack developer, I build web products that really run in production.

Do you have a SaaS, a business tool, or a platform to develop (or to fix)? I take the subject from end to end: architecture, back, front, database, deployment, and monitoring. You describe your business need, I deliver something that works, that can handle the load, and that you can evolve without being overwhelmed by technical debt.

What I concretely bring you: a developer who understands the business before writing a line of code. I work a lot with demanding French platforms (health, administration, B2B) where the rules are complex and where a mistake is costly. I don't just "do the feature": I challenge the need, I anticipate tricky cases, and I deliver clean, documented code.

What sets me apart: I cover the entire technical chain. Angular, React, and Next.js on the interface side, NestJS on the API side, PostgreSQL and MySQL in the database, and deployment (Azure, GCP, Supabase, Docker, Nginx) without depending on an external DevOps. A single point of contact who masters the entire stack: you gain in velocity and clarity. I also have a real product mindset, I think in terms of users and value, not just tickets.

Types of projects I work on:

SaaS and business tools from scratch, from design to production

Taking over and refactoring existing applications: migration, performance, technical debt

Complex integrations: third-party platforms, APIs, automations

Chrome extensions and web workflow automation

Document processing: OCR and parsing of French business documents (quotes, Kbis, SIRET)

Performance optimization and monitoring (Datadog, network and database bottlenecks)

Stack: Angular, React, Next.js, NestJS, Node, TypeScript, PostgreSQL, MySQL.

Available on a fixed-price or hourly basis. If your project needs to be truly finished, we'll get along well.
