Full-Stack Software Engineer — I build fast, playful products.
I’m Shahin — a software engineer with 5 years shipping production software for high-traffic platforms. My happy place is the seam where an elegant interface meets a fast, well-architected backend.
Today I lead engineering at Cartup Ltd. Before that, at TechnoNext and Morpheus Soft, I built front-end teams, designed micro-service boundaries, and wired AI into real products — always optimizing for performance, accessibility, and developer joy.

From an internship building approval workflows to leading product squads — here's the path.
Apr 2026 — Present · Dhaka, BD
Driving engineering for one of Bangladesh’s largest online marketplaces — owning the storefront, search and order pipeline end to end, and keeping checkout resilient through flash-sale traffic spikes on a Next.js and .NET stack.
Jan 2023 — Mar 2026 · Dhaka, BD
Lead engineer on travel and e-commerce platforms. Ship full-stack features with Next.js, .NET and Node — from booking flows handling millions of fares to authenticated dashboards used by ops teams.
Dec 2021 — Dec 2022 · Dhaka, BD
Built a biometric (palm-scan) OAuth product on WebAssembly and React. Delivered a crypto trading dashboard plus several customer-facing OTA flows.
Aug 2021 — Nov 2021 · Dhaka, BD
Implemented an internal approval system and authored a fast in-memory search index that cut page load by ~60%.
No religion about any single tool — picked because they fit the problem, not the resume.
Scroll to leaf through five real, live, in-production platforms — they stack as you go.
One of Bangladesh’s largest online shopping platforms — flash sales, multi-seller marketplace, real-time inventory and a checkout that survives Black Friday. I work on the storefront experience, search, and the order pipeline.
Open site
A nationwide food-delivery network with restaurant onboarding, live order tracking, and a logistics dashboard for fleet managers. Built around a microservice estate with Kafka-driven order events.
Open site
Bangladesh’s top travel booking platform — flights, holidays, visas and eSIM in one app. I led the flight search experience, partner-airline integrations and the student fare flow.
Open site
A US telehealth platform connecting patients with board-certified physicians for personalized GLP-1 weight-management plans. Discreet onboarding, secure intake, and a member portal for ongoing care.
Open site
Booking, check-in and loyalty (Sky Star miles) experience for a major regional carrier flying across Asia and the Middle East. Live flight status, self-service rebooking and a content-driven holiday store.

I’ve worked with a lot of contractors. Shahin is in the top one percent for ownership. He treated our codebase like his own — refactored quietly, wrote tests, left it cleaner than he found it.
The AI search integration Shahin built for our marketplace doubled the click-through on product discovery. Calm, methodical, and the docs were better than ours.
I take on a small number of engagements each quarter — long-term contracts, fractional engineering leadership, and the occasional weekend AI experiment. The fastest way to reach me is email.
