Senior Full-Stack Engineer with 5+ years and 20+ production apps delivered across MERN, NestJS, and Next.js.
I specialize in REST APIs, GraphQL microservices, and payment integrations (Stripe, PayPal, Apple Pay) — building systems that scale without breaking under pressure.
What you actually get: clear communication, proper architecture from day one, zero hand-holding required, and real post-delivery support — not a ghost after you leave a review.
If you need it built right the first time, let's talk.

FAQ
Which AI models do you work with?
I work with OpenAI (GPT-4/GPT-5), Claude, Gemini, and other LLMs depending on your project requirements.
Can you build AI chatbots trained on my own documents?
Yes. I build RAG-based chatbots that can answer questions using your PDFs, Word documents, websites, Notion pages, databases, or other knowledge sources.

Yes. I can deploy your project to AWS, Vercel, DigitalOcean, Render, or other cloud platforms. Docker deployment is also available.
