Adil R.

Full-stack AI developer for SaaS teams and founders. I build Next.js products, add Claude and OpenAI agents that do real work, and fix existing apps so they hold up with real users. Whether you're launching an MVP, scaling a product that's starting to struggle, or taking over a codebase someone else (or an AI tool) built, I work across frontend, backend, database and AI to get it production-ready without unnecessary rewrites. I bring 7+ years of engineering experience, including SAP Signavio and high-traffic delivery and ride-hailing platforms, plus 40+ completed projects here on Upwork.

You get maintainable code, honest technical advice and someone who cares how the app runs in real use. Send me your repo, idea or the problem that's blocking you, and I'll tell you the most practical way forward.
