About

Sa.

I build uncommon digital products that feel fast, clear, and built to last.

  • Product architecture
  • Performance-first UI
  • Scalable APIs

I'm Smail, a fullstack developer based in France with 3 years of production experience across startups and enterprise teams (including Auchan group).

My core stack includes TypeScript, React, and Node.js. I care deeply about code quality, maintainability, and performance under real usage.

I have worked with early startups and scaling teams on complex interfaces, high-throughput APIs, and long-term product foundations.

Outside client work, I continuously build internal tools and exploratory concepts to sharpen both engineering and design thinking.

I care about shipping fast without cutting corners - clean architecture, typed codebases, and maintainable code that teams can actually work with long-term.
