Back to original languageAbout Slimane
Full Stack Developer specialized in Data Science and AI, I assist companies and freelancers in creating performant and scalable web solutions. With several experiences in freelance, work-study, and startup missions, I have designed applications ranging from optimized landing pages to complete SaaS for doctors, including the development of high-performance APIs (up to 700 requests/sec).
I master a wide range of modern technologies: Next.js, React, Node.js, GraphQL, PostgreSQL, TailwindCSS, AWS/GCP, with solid experience in DevOps (Docker, NGINX, Traefik).
What sets me apart: my ability to translate your business needs into concrete solutions, while ensuring robustness, scalability, and polished design. My background has led me to work with diverse clients (international freelance on Fiverr, scale-ups like Bellman, medical startup Sanus), which allows me to bring a versatile and results-oriented vision.
