About this gig
Transform your idea into a secure, production-ready AI application.
I am a Full-Stack Engineer specializing in custom AI Chatbots and SaaS MVPs. I don't just paste API keys; I build scalable, secure architectures using Next.js, Node.js, and OpenAI/Claude APIs.
What I deliver:
- Secure AI Integration: Connect OpenAI, Claude, or Gemini with input sanitization and BYOK (Bring Your Own Key) support.
- Modern Full-Stack: Fast, responsive frontends using Next.js 16, React, and Tailwind CSS.
- Robust Backend: Node.js/Express APIs with authentication (JWT/OAuth) and optimized databases (MongoDB/PostgreSQL).
- Production Deployment: CI/CD pipelines via GitHub Actions and Docker for reliable hosting.
Why me?
I have shipped 4 real products featuring LLM integration and real-time collaboration. I write clean, commented code that you actually own.
Not sure which package fits?
Message me, and I will consult with you to find the best solution for your project.
