Dhaka, Bangladesh - 1:39 am local time
I build AI agents for travel that can actually book — grounded in real flight APIs, not just a chat box. The reason most travel bots fail is weak tooling; I bring 4,000+ Upwork hours of GDS/NDC integration so the agent has reliable search, pricing, PNR, and ticketing to call.
Across 127 completed jobs, I've helped OTAs, agencies, and startups connect global flight content and turn it into working booking platforms — and now into conversational, agentic experiences.

What I do:

AI agents for travel — LLM-powered flight search and booking assistants, conversational itinerary building, function/tool calling into GDS/NDC APIs, MCP integrations, and RAG over fare rules and policies so answers stay accurate. Agents that take real actions, not just suggest them.

Flight API & GDS/NDC integration — Amadeus (SOAP & REST), Sabre, Galileo/Travelport, and NDC channels: search/pricing, PNR creation, ticketing, void/refund/reissue, ancillaries, and fare rules including ATPCO Mini Rules (Cat 31/33).

Full-stack travel platforms — ASP.NET Core / C#, Node.js, EF Core + PostgreSQL, Redis caching, schedulers, secure integrations (X.509/mTLS, OAuth, OTP), plus B2B/B2C/admin and mobile front ends. The whole booking system when you need it.

I care about integrations that ship and agents you can trust in production — clean code, clear communication, and someone who understands the travel domain end to end.
