About

Full-stack engineering, amplified by agentic AI.

I'm SalahEddine—a senior full-stack web developer based in Morocco. Across 6+ years, I've contributed to 20+ products using React, TanStack, Symfony, and Laravel, from marketplaces to B2B SaaS platforms.

AI agents are part of every stage of my workflow: discovery, architecture, implementation, testing, debugging, and documentation. I direct the process and validate the output to ship coherent, production-ready software end-to-end.

  • Addicted to problem-solving

    I like hard problems. The messier the requirement, the more fun it is to turn it into something clean and usable.

  • Own the whole stack

    I connect product decisions with interfaces, APIs, data, security, and deployment so the entire system works as one.

  • Agents accelerate, judgment leads

    I use AI agents across the entire delivery cycle while keeping architecture, quality, security, and final decisions under human direction.
