I'm a full-stack developer based in Dhaka, building production web and mobile apps with React, Next.js, TypeScript, and React Native. Day to day I work across the stack, from clean interfaces in Tailwind and ShadCN UI to solid backends in Node.js, Express, Django, and MongoDB.
I've helped build a SaaS product from the ground up, so I care about architecture and maintainability as much as shipping fast. I write code that the next developer, often me months later, can actually read.
If you want someone who asks the right questions before touching a line of code, let's talk.
My Portfolio
FAQ
What's your process? Do you start coding right away?
No. I start with understanding. I ask about your goals, existing systems, timeline, and budget constraints. Then I outline the approach in writing before touching a line of code. This saves time and prevents expensive rewrites later.
Can you work with my existing codebase?
Yes. If you have an existing project, I can review it, understand the architecture, and extend or fix it. Just share the github/gitlab/codeberg repo and we'll discuss scope. There's usually an additional consultation fee for legacy code assessment.
Do I get the source code?
No, the BASIC package does not include source code. However, other packages includes complete source code. You own what I build. You can use it, modify it, or hand it to another developer later.
What if I need revisions?
They're built into each package. BASIC includes 1 round, STANDARD includes 3, PREMIUM includes 4. Major scope changes outside the original agreement are quoted separately.
How long does a typical project take?
Delivery times are listed per package, but honestly it depends on your feedback speed and how clear the requirements are. Fast feedback means faster delivery. Slow feedback pushes the timeline back.
What about hosting and deployment?
I'll deploy to Vercel (frontend) and suggest options for backend hosting (Heroku, Railway, DigitalOcean). I include deployment guidance, but ongoing hosting costs are your responsibility. I can help you set it up though.
Do you provide ongoing maintenance after delivery?
Not as standard, but I offer 30-day post-launch support in the PREMIUM package. After that, we can discuss a maintenance retainer if needed.
Why are your prices different from other "cheaper" developers?
Speed and quality. A cheap developer might take 3 weeks and hand over broken code. I deliver working, scalable code faster. You're paying for experience and accountability, not just hours.
What happens if I'm not happy with the work?
We fix it. That's what revisions are for. If we fundamentally disagree on the direction, we discuss it before going further. My goal is your satisfaction.
Do you sign NDAs or contracts?
Yes. For larger projects, especially PREMIUM tier, I'm happy to discuss NDAs or work agreements. Fiverr's Terms of Service cover most cases, but we can add specifics if needed.
