“Programs must be written for people to read & only incidentally for machines to execute.”— Harold Abelson
A pragmatic, modern toolkit spanning the full stack — chosen for reliability, performance & developer experience.
A few non-negotiables that shape each technical decision, from the first sketch to production support.
Software should be dependable under real load. I optimize for correctness and resilience before cleverness.
The best code is the code the next engineer understands instantly. I write for humans first.
Speed is respect for the user's time. I treat performance budgets as first-class requirements.
From the database to the pixel, I take end-to-end ownership of what I ship.
Full-stack engineering services for teams and founders who need one engineer accountable for the whole build.
End-to-end web apps built to scale.
I design and ship complete web applications — from database and API to a fast, accessible React and Next.js interface. One engineer accountable for the whole stack, so nothing falls between the cracks.
Fast, conversion-focused online stores.
Custom e-commerce experiences that load fast, rank well & convert — from headless storefronts and secure checkout to product catalogs, carts & payment integrations built to handle real traffic.
Internal tools your team runs the business on.
Role-based admin platforms and internal tools that stay consistent as they grow — built one from scratch to 80+ modules covering inventory, orders, CRM, HR, accounting & finance & reporting for a healthcare platform serving real operational teams daily.
A simple, visible cadence that turns an idea into reliable software without losing momentum or context.
We start with your goals, constraints & timeline. I map the problem, clarify requirements & turn ambiguity into a clear, prioritized plan.
I design the data model, API surface & system architecture up front — choosing the right tools so the product stays fast and maintainable as it grows.
You get working software early and often, with tested, reviewed code and regular check-ins so we can adjust direction based on real feedback.
I handle deployment, monitoring & performance, then stay available for iteration and maintenance so the launch is a beginning, not a handoff.
A few builds I'm proud of — spanning full-stack apps, backend systems & open-source work.
Smart parking management platform connecting drivers with parking-space providers.
Bilingual blogging platform for the developer community (Bengali & English).
End-to-end authentication with React, Redux & NestJS.
Building and scaling products across healthtech, e-commerce & open source.
I’m a Senior Software Engineer specializing in building scalable, high-performance web applications and backend systems. My experience spans both frontend and backend development, with a strong focus on delivering clean, maintainable & production-ready code.

“I had the pleasure of working with him at Arogga Ltd, and I am thrilled to provide a recommendation for them. He is an exceptional frontend developer with deep expertise in React and a profound understanding of modern web technologies. During our time together, he consistently demonstrated a high level of skill and creativity in developing web applications. Their ability to translate complex requirements into seamless, efficient code was truly impressive. They are not only proficient in React but also excel in utilising HTML, CSS, and JavaScript to create robust and scalable solutions. I highly recommend him for any frontend development role. They will undoubtedly be a tremendous asset to any team and contribute significantly to the success of any project they undertake.”
“He is a remarkable and helpful team player whom I have worked with so far. He understands his teammates and judges them according to their mentality. He is humble and passionate about his duty. He is always helpful to me. He is a very quick learner and always have the kind mentality to share his knowledge with co-worker and teammates. His judgemental power and patience for his work encourage me every day.”
Thoughts on engineering, architecture & building for the web.
The WebSocket demo works in five minutes. The problems start after: reconnection, authenticating a long-lived connection, events missed while a client was away & what happens when you run more than one server. Notes from building event-driven real-time systems for real users.
Caching is sold as a performance win and paid for in staleness bugs. A look at the actual decision: which reads are worth caching, how to invalidate without lying to users & the cases where adding a cache creates more problems than the latency it removes.
At a handful of screens, copy-paste is fine. At eighty, it's the thing that kills you. A look at the resource abstraction that held a large admin platform together — and the escape hatches that kept it from becoming a straitjacket.
The working relationship is as important as the code: clear ownership, steady communication & a focus on outcomes.
From architecture and interface work to deployment and iteration.
Regular check-ins, working software early & direct communication.
