I build and ship AI-powered web applications from idea to production.
My work includes AI agents, LLM integrations, RAG, tool-calling, real-time systems, and full-stack development with Next.js, React, TypeScript, Node.js, and PostgreSQL.
I've built and deployed three live AI products, including a multi-model AI SaaS platform, a real-time voice AI app, and an agent-based expense tracker.
I focus on building practical, production-ready systems — not just demos — and handle projects end-to-end, from architecture to deployment and debugging.
Live examples available on request.

FAQ
What information do you need to get started?
Please share the error message or issue you're experiencing, along with access to your repository or details about your setup (framework version, hosting platform, etc).
Can you fix issues without full access to my codebase?
In most cases, I'll need read access to your repository (GitHub, GitLab, etc.) to properly diagnose and fix the issue. Access to your deployment platform (such as Vercel) may also be needed depending on the problem.
Do you fix bugs in any tech stack, or just Next.js/React?
I specialize in Next.js, React, and Vercel deployments, but I'm also comfortable working across the broader JavaScript/TypeScript ecosystem. Message me with your specific issue before ordering if you're unsure.
What if the bug turns out to be more complex than expected?
If the scope changes significantly after investigation, I'll let you know before proceeding. We can then discuss upgrading to a higher package or creating a custom offer.
Will you tell me what caused the bug, not just fix it?
Yes. I'll explain the root cause and the fix so you understand what happened and can avoid similar issues in the future.
