Master Calculator Pro
Everyday maths. Serious engineering.
An all-in-one calculation app that brings everyday maths, financial tools, AI assistance, and graph plotting into one place.
INDEPENDENT ENGINEER. ENDLESSLY CURIOUS.
Ideas are
everywhere.
I make them
real.
I’m Priyanshu. I turn ambitious ideas into Android apps, useful web experiences, and tools that go a little deeper.

02 / THE CURIOSITY NEVER STOPS
A little beyond
the usual.
Sometimes it’s a language. Sometimes a game. Always a reason to learn something by building it.

03 / SERVICES & COLLABORATION
Your next idea.
Let’s give it a life.
Work directly with the person building your product. From a focused feature to a first release, we’ll shape a scope that makes sense.
Android apps, from idea to Play.
A focused first release or a thoughtful upgrade to an existing Android product.
- Kotlin / Java & Jetpack Compose
- API and Firebase integration
- Release preparation & Play Store support
Web products with a purpose.
Tools, learning platforms, and custom experiences that turn a specific problem into a usable product.
- Responsive web interfaces
- Interactive tools & dashboards
- API integration & product workflows
AI that fits the product.
Bring useful AI features into an app or explore a focused machine-learning prototype.
- Conversational & multimodal features
- AI API integration
- Python tooling & ML prototypes
Make your app run better.
Find the friction in an Android app or NumPy workflow, then agree on focused improvements.
- Android startup & resource review
- Memory and allocation diagnostics
- Refactoring & technical documentation
HOW WE’LL WORK
01
Get clear.Problem, audience, and scope.
02
Build together.Agreed milestones and feedback.
03
Make it real.Delivery, documentation, and handoff.

04 / THE PERSON BEHIND THE PROJECTS
Engineer by craft.
Builder by instinct.
I like the whole journey: the first question, the stubborn bug, the moment someone actually uses what I’ve made.
I started Raut Masters in 2020. Since then, I’ve been building and maintaining Android apps, exploring systems engineering, and sharing what I learn. I’m studying Computer Science & Engineering at Meghnad Saha Institute of Technology, with graduation expected in 2028.
My work moves between the practical and the curious: an app for everyday maths, a tool that explains memory, a programming language, a game. Writing fiction is another way I practise making complicated ideas feel human.
BUILDING PEOPLE, TOO.
Knowledge grows
