Senior Full-Stack Developer with 8 years of experience specializing in AI-powered applications, Azure cloud architectur. I build scalable, production-ready applications across the entire Microsoft stack and modern web technologies. My expertise includes: AI Integration & Development (OpenAI, custom AI solutions) Azure Cloud Services & Architecture .NET/C# Backend Development (APIs, microservices, enterprise applications) Modern Frontend (Next.js, React) Authentication Systems (Supabase, Azure AD, OAuth, multi-provider SSO) Production Support & Critical Bug Resolution Clean Architecture & Technical Documentation I deliver high-quality code, comprehensive technical documentation, and proactive problem-solving. Whether it's architecting cloud infrastructure, integrating AI capabilities, building .NET APIs, or resolving complex production issues, I focus on solutions that scale.

Need your SaaS taken from idea to shipped, the whole build, frontend, backend, database, auth, and payments, by one engineer instead of three different freelancers? That's exactly what I do. I ship production apps founders can launch on, not half-finished demos. Most early-stage SaaS doesn't fail on design. It fails on what's underneath: messy state, slow pages, and a backend that cracks the moment real users arrive. I own the full stack, from the React interface down to the API and database, so the pieces fit and hold up as you grow. What I build for you: - Full SaaS builds and MVPs, from Figma or a rough idea to a live product - Dashboards and admin panels: analytics, role-based access, real-time data, bulk operations - Backend and APIs: auth, Stripe payments, REST APIs, clean data models - AI features inside your product: LLM integration with the OpenAI and Claude APIs, smart search, chat, and automation built into real apps - Frontend that lasts: fast loads, clean architecture, reusable components your team can extend Stack: Next.js, React, TypeScript, Laravel, Supabase / PostgreSQL, Tailwind, Redux, Stripe, REST APIs, OpenAI / Claude APIs Recent work: - ImmoDesk, a real-estate SaaS in Next.js 15 and TypeScript: RTK Query across 15 data entities, a bulk-operations framework, smart Excel/CSV export, and full FR/EN internationalization (500+ keys) - Tanger Stylo, a complete e-commerce platform, storefront plus admin backoffice, on Next.js and Laravel: inventory, orders, customers, and discounts. I hold a 100% Job Success Score because I scope honestly, communicate clearly, and deliver what I promise. I won't overclaim to win a job and leave you with a mess to clean up. Send me your Figma, your repo, or one line about the problem you're solving. I'll reply within a few hours with a clear build plan, not a generic pitch.
