A BIT ABOUT ME

I Like Building Things (And Figuring Out Why They Break)

I'm a B.Tech student who keeps asking "why?" about spacetime, about security, about why a kid in a village can't access a good tutorial. I don't always have answers. But I keep looking.

I'm fascinated by two things: how the universe works at the smallest scales, and how to build useful things with code. Right now I'm working on a personal research project I call the Chronon Model basically trying to simulate what spacetime might look like if it were made of tiny discrete pieces. It's very much a work in progress. I also build smaller, practical stuff like a data science portal for my college and a little e-commerce site called ShopRoyince.

I started a small initiative called HOPE it's basically me trying to combine a few things I care about: teaching, building, and helping students who don't have access to good resources. Over the past few years, I've been lucky enough to help around 430 students get their hands dirty with cybersecurity labs and Arduino/ESP32 projects.

Physics (The Deep End)

Exploring what spacetime might be made of at the smallest scales. The math is hard. The questions are harder. I love both.

Building Stuff

Websites, apps, and circuits that (mostly) work

Teaching (And Learning From Students)

Teaching students security and hardware. They keep me honest.

Breaking Things (Responsibly)

Finding vulnerabilities before they get exploited. IoT devices and web apps are my usual hunting ground.

"Still learning. Still building. Still curious."

THINGS I'VE BUILT

Stuff I've Made

Here's what I've built over the years. Some are polished. Some are rough. All of them taught me something.

HOPE Platform

A collection of projects I built around one idea: making tech education accessible

EDTECH

HOPE Platform

My attempt to combine teaching, e-commerce, IoT, and physics into one platform. It's not perfect. But 430+ students have used it, and that's what matters.

Chronon-Super Quantum Level Model

Simulation code for a discrete spacetime model I've been developing. It's experimental, the math is ongoing, and I'm the first to admit it's not finished. But the results so far are interesting.

RESEARCH & CURIOSITY

Things I'm Trying to Understand

A few questions I couldn't let go of. Some are physics. Some are security. All of them started with a "why?"

Active

Chronon-Super Quantum Level Model

A personal research project where I'm trying to model spacetime as discrete chunks tiny units of time ("Chronons") and space ("Space Grains"). It's inspired by loop quantum gravity and causal set theory. I'm not claiming to have solved anything. I'm a student working through the math, one equation at a time. But the framework is real, the simulations run, and the questions are worth asking.

Q-SAFE Environment

A security tool I've been building that combines an x86 Assembly module for low-level system checks with a Python ML model for detecting suspicious code. I call the architecture "Hybrid Trinity" because it has three layers. It's a working prototype with a 100% detection rate and 1.39% false positive rate in testing. I'm proud of it, and I'm still improving it.

Age 13

At 13, I broke a phone and tried to fix it. Ended up learning assembly language instead. Understood maybe a third of it. Kept going anyway. The other two-thirds came later.
