Independent developer · Durgapur, India · taking new projects
People have installed my apps more than 500,000 times. They include a CPU throttling test, an offline PDF toolkit, a bill splitter and a mood diary. I build client projects the same way. You talk to the person writing the code, and when we're done, you own every line of it.
My own apps
Each one started with a small, specific problem. The newest ones have their own websites, so you can see how I present a product end to end.

The one that took off
Phone reviewers kept saying chips “throttle” under load, but there was no simple way for an ordinary person to see it happen. The tools that existed were either too technical or not accurate.
So I built CPU Throttling Test. You tap once, it runs the processor flat out, and it draws the slowdown as a graph you can actually read. Then I added a ranking of more than 3,000 devices, so you can see how your phone compares.
I handled the design, the Kotlin code, the benchmarking engine, the Play Store listing and the monetisation myself. That's the same full-stack ownership you get on a client project.
In their words
These are unedited reviews from real users, copied as written.
This app proved that the Unisoc T760 on my phone is a good entry level chip able to sustain performance even when temperature had peaked at 43°C.
Just tested the CPU Throttle app on my setup during a heavy workload session. It effectively capped temps at 85°C, preventing crashes. Worth it for laptops. 7/10.
It was very helpful for my phone. I could use very easily.
Work with me
You don't need a design or a spec to start. Most projects begin with a rough idea and a 30-minute call.
From the first sketch to a live Play Store listing, including screenshots, store copy and a launch plan. This is what I've done a dozen times for my own apps.

Pricing
Every project is quoted in writing before we begin, and the source code is always yours.
A one-page website or a very simple app
₹1,000 starting
A focused app, website or tool
₹10,000 starting
Most projects land here
A multi-feature product with a backend
₹50,000 starting
Custom builds, AI features and scale

It depends on scope. A landing page or single-feature app takes 1–3 weeks, and a multi-feature product with a backend is usually 2–4 months. You get a clear timeline in the proposal before any work begins.
Yes, always. Once the project is paid for, you own all the code, designs and assets. There's no lock-in, and nothing depends on me.
In milestones: usually 30% to start, 30% at the midpoint and 40% on delivery. Smaller projects are 50/50. You never pay the full amount before seeing working software.
Every plan includes 30–60 days of support after launch. After that, you can keep me on a monthly retainer or ask for changes one task at a time.
Yes, happily, and before we discuss any details. Your idea and your data stay confidential.
Yes. I can take over, fix or extend Android, React Native, web or backend projects. I'll review the code first and give you an honest assessment before quoting.
Yes. That's what the free call is for. We'll work out the right scope and budget together, with no commitment.
