I'm a senior full-stack engineer with 11 years of experience building production-grade web applications, with a strong focus on SaaS products, AI integrations, and modern cloud architecture. My core stack is Next.js, TypeScript, Supabase, and AWS — I use these to take ideas from zero to deployed, working products. I've built multiple SaaS products end to end, including developer tooling and AI-powered automation systems. What I do best: SaaS MVPs built fast and properly — not prototype quality, production quality AI API integrations (Claude, OpenAI, custom LLM workflows) Authentication, billing (Stripe), multi-role access, and database architecture Clean, maintainable TypeScript codebases you won't regret inheriting Full deployment on Vercel and AWS — you get a live product, not just local code How I work: I scope carefully before starting. I'll ask the right questions upfront, push back if something doesn't make sense, and keep you informed throughout. I only take projects I'm confident I can deliver well. If you're a founder or technical lead who needs a reliable engineer to build something real — let's talk.

My career as a web developer started 10+ years ago in which time it has proven that I am even better at coding and slicing. React and Material UI are the areas in which I excel so I became a Front-End developer but I am also familiar with back-end development languages like ExpressJS and PHP(Laravel). Also, I am ready to learn new ones and expand my current knowledge of the fore mentioned as needed to the point where it makes me do my job as a Front-End developer, faster, better and more efficiently. That is the way I dived into web programming in the first place and started to like it through the learning process. Specialties: - Front-End development (React, AngularJS, Vue.js, Material UI, Sass, Styled Component) - Back-End development (Laravel, ExpressJs, MySql, MongoDB), although I'm stronger on the front-end side - Web Standards - Usability & Accessibility
