Md. Shahin Sheikh
Full-Stack Software Engineer
Five years building the software that cannot afford to go down — marketplaces, booking engines and checkout flows for some of the busiest platforms in Bangladesh.
Dhaka, Bangladesh
I build the part users touch — and the part that keeps it standing.
I’m Shahin. For five years I’ve worked on systems that get judged in public: a national marketplace on flash-sale day, a flight search quoting thousands of fares at once, a checkout that has to clear on the first try.
Today I’m an engineer at Cartup, owning the storefront, search and order pipeline. Before that, at TechnoNext and Morpheus Soft, I led front-end teams, drew micro-service boundaries with gRPC and Kafka, and wired AI into search and support. The through-line: an interface that feels effortless, on a backend that earns it.
Day to day
- Ship end to end — React and Next.js on the front, .NET and Node behind it
- Design micro-service boundaries with gRPC, Kafka and Redis
- Keep search and checkout fast when traffic spikes
- Wire AI into real surfaces: search, support, recommendations

Shahin moves between a Figma file and a production .NET service without dropping either. He shipped our checkout rewrite a sprint early, and it held on launch day.
Md. Rafiqul AlamEngineering Manager · TechnoNextHe treated our codebase like his own — refactored quietly, wrote the tests, left it cleaner than he found it. That is rarer than it should be.
Preet S.CTO · Corsica HealthThe AI search Shahin built for our marketplace lifted click-through on product discovery measurably. Calm, methodical, and his documentation was better than ours.
Md. Mehedi HasanSr. Team Lead · CartUpDeep technical range, a real sense for design, and the kind of teammate who makes a project easier to be on. We bring him back whenever we can.

Have something worth building?
I take on a small number of engagements each quarter — long-term contracts, fractional engineering leadership, and the occasional weekend AI experiment. Email reaches me fastest; tell me what you are building and where it hurts.
