Featured case study
A full-stack travel discovery platform combining real traveler ratings with an AI chat assistant.
Internship capstone
A multi-tenant backend that tells every customer how much they've used, what it costs, and whether they've hit their plan limit.
AI token counts are simulated and Stripe runs in test mode only.
GitHubInternship capstone
Customers build a form widget, paste one script tag into any site, and collect submissions in a dashboard.
Geo lookups and email are mocked by default, and rate limit counters live in the memory of one server process.
GitHubInternship capstone
Turns one blog post into a social campaign: a variant per platform, a human approves each one, then a scheduler publishes.
Variants come from templates, not an AI model, and the API has no authentication.
GitHubAbout
I'm a self-taught full-stack developer from Chattogram (Chittagong). My formal programming journey began in 2025, though I'd been absorbing how software is made long before I wrote my first line of code. Since then I've built and deployed complete products: a gym management platform, a doctor appointment system, a travel discovery platform with an AI assistant, and a crowdfunding app.
What I enjoy most is the moment a hard problem finally makes sense. I try to build the parts users never see but always depend on: role-based access, payments, scheduled jobs, and graceful handling of retries and dropped connections.
In 2026 I completed the FlyRank AI Internship Program in the Backend AI Engineering track. Each of my three approved capstones ships with a design document, a build log and recorded evidence of its checks, along with a plain list of what it does not do.
Away from the keyboard, you'll find me with a book, any genre, or playing football.
Booking a doctor, managing a gym, planning a trip. Every project starts from someone's actual need.
React and Next.js interfaces, Express APIs and MongoDB schemas, built as one system with clear boundaries between the parts.
Responsive, accessible and quick to load, built with Tailwind and Framer Motion.
JWT auth, role-based access, idempotent writes, verified webhooks and honest error codes are planned in from the start, not patched on.
