Hi, I am Salman Biswas 👋

Emerging Developer · Reverse Engineer · AI-Assisted Builder

I’m an emerging, original developer from Bangladesh. I build websites, Telegram apps & bots and Android APKs across frontend, backend and mobile — including AI-assisted development as part of a modern workflow. Alongside building, I reverse engineer apps: analysing how they work, debugging them and patching them.

About me

A developer who sketches first, then codes

I’m Salman Biswas, an emerging, original developer based in Bangladesh — early in my journey, learning fast and building real things. I build websites, Telegram apps and bots, and Android APKs, working full-stack across frontend, backend, databases and deployment.

I also work as a reverse engineer — taking an app apart to understand how it really works, through app and APK analysis, app modding, binary and network analysis, debugging and patching. Building and reverse engineering go hand in hand: create something, then open it up and see what’s inside.

My workflow includes AI-assisted development — prompt engineering, rapid prototyping and automation for repetitive tasks — alongside hands-on coding and reverse engineering. It keeps projects moving quickly, from first idea to a working build.

FAQ

Questions people ask me a lot

What kind of projects do you take on?+

Websites and full-stack web apps, Telegram apps and bots, Android APKs, REST APIs and AI-powered apps — plus reverse engineering work on existing apps. If something sits outside what I can do well, I’ll say so upfront and point you in the right direction.

How experienced are you?+

I’m an emerging, original developer — early in my career, building real projects and learning fast. I’m upfront about what I can do, and what I offer is solid coding skill, careful work and straight answers.

What does your reverse engineering work involve?+

App and APK analysis, app modding, binary and network analysis, debugging and patching. In plain words: I open an app up, work out how it behaves and where it breaks, then patch or modify what needs changing.

How do you use AI in your work?+

AI-assisted development is part of my everyday workflow — prompt engineering, rapid prototyping, debugging support and automation for repetitive tasks. It pairs naturally with hands-on coding across web, bots and Android, and with reverse engineering work.

How long does a typical project take?+

A simple landing page usually takes 3–5 days, a full web application 1–3 weeks, and larger platforms or AI-powered apps 2–6 weeks depending on features. You get a clear timeline before we start, plus small previews along the way — no disappearing for weeks.

Will my site work well on cheap phones and slow internet?+

Yes — that’s my specialty. I hand-code lightweight pages, compress every image, and test on low-end devices. Your site stays fast even on a slow 3G connection in a crowded bus.

Do you use templates or page builders?+

No. Everything is written from scratch, which means your site doesn’t look like a thousand others, loads faster, and is easier to change later. You own the full code when the project is done.

How much does it cost, and how do payments work?+

Every project gets a fixed quote after a short chat about scope — no hourly surprises. We usually split it into a small start payment and the rest on delivery.

Can you redesign or fix my existing website?+

Absolutely. Send me the link and I’ll do a free quick check-up: what’s slow, what looks broken on mobile, and what I’d fix first. Then you decide if you want the full makeover.

Do you help after the site goes live?+

Yes. Every project includes a support window for fixes and small tweaks, and I can stay on for updates, new pages or features whenever you need them.
