Fullstack & AI integration
Java Spring Boot or Python FastAPI backends, REST/GraphQL APIs, and shipping AI features (LLM, RAG, semantic search) inside your React apps.

Frequently asked questions
Are you available for a freelance React project in Paris?
Yes — remote across Europe, hybrid, or on-site in Paris (Île-de-France). I take both short and long engagements. The fastest way to check availability is to book a call on Collective or reach me on Malt.
Do you work with Next.js and TypeScript?
Yes — strict TypeScript by default, and Next.js (App Router, SSR, React Server Components) as needed. I also work with Vite, state management (Context, Zustand, Redux) and Tailwind / shadcn design systems.
Can you act as a tech lead, not just a developer?
Yes. I've led teams of up to 4 developers: architecture decisions, code reviews, CI/CD setup on GCP, mentoring. I can operate as a hands-on lead or as an architect depending on what the project needs.
Do you also do back-end and AI work?
Yes — I'm fullstack. Java Spring Boot or Python FastAPI backends, REST/GraphQL APIs, and AI feature integration (LLM, RAG, semantic search). For example, I shipped a 6× faster AI property search at Upfund.
What are your rates and how do I book you?
My day rate starts at €600/day (excl. VAT), adjusted for length, scope and remote/on-site. Book a 30-min call on Collective (app.collective.work/collective/ali-el-mufti) or reach me on Malt — I usually reply within one business day.
