Md RefatBhuyan
Full-Stack & AI Engineer at Cunard Consulting Ltd, UK. I rescue stalled AI projects, help local businesses go digital (EcoEats: 150K+ customers), and ship production MERN + LangChain systems — zero missed deadlines.
Key Statistics
Developer who actually delivers.
I'm Md Refat Bhuyan — a Full-Stack Developer and AI Engineer working remotely with Cunard Consulting Ltd, UK. I build production software that ships: AI-powered chatbots, real-time banking systems, and full e-commerce platforms — delivered on time, without hand-holding.
My edge is combining a B.Sc. in Electrical & Electronics Engineering (CGPA 3.81/4) with hands-on LLM engineering — I've integrated LangChain and RAG pipelines into live fintech products, not just side projects. I'm certified in Full-Stack Development and SQA & Cyber Security.
Open to full-time remote roles, senior contract work, and early-stage founding engineer conversations — particularly in fintech, AI tooling, or developer infrastructure.
I work with clients in the UK, US, UAE, Australia, and beyond. Based in Dhaka (GMT+6) — morning overlap calls with UAE (GMT+4), UK, and Australian teams are easy.
Does this sound like you?
Three types of clients I solve real problems for — pick yours.
Built with AI. Got stuck.
You started with Cursor, Claude Code, or ChatGPT. Your app is 80% done — but it's broken in production, your RAG pipeline hallucinates, or the code is a spaghetti mess no one can maintain.
- LangChain / RAG pipeline not working
- Vibe-coded app needs a real engineer
- Context engineering & prompt architecture
- Ship it properly — tested, deployed, live
Real business. Ready to grow.
You run a restaurant, salon, clinic, or shop. You want customers to find you online, order from you, book you — and you want AI to handle the enquiries you can't.
- Full website + online ordering / booking
- Google-ready SEO from day one
- AI chatbot — answers 24/7, no staff needed
- Built to scale with your business
Broken app. Missed deadline.
Your previous developer disappeared. The app is slow, buggy, or half-finished. You need someone to come in, understand the codebase fast, and fix it — no drama, no excuses.
- Code audit & bottleneck fix in 48h
- Complete half-built features
- Performance, security & stability review
- Ongoing retainer if you want a safety net
