The flagship. An AI exercise coach that runs entirely on the phone — it recognises 7 exercises on its own, counts your reps, scores every one 0–100, and coaches you out loud, all on the Snapdragon Hexagon NPU. No cloud, no backend — the app doesn't even request the
INTERNET permission, so the camera feed never leaves the device.
Stack: Java · Android · SNPE · Hexagon NPU · YOLO-NAS · HRNet · on-device TTS · 120+ test harness
On-device deepfake detection + cryptographic provenance.
Real-time deepfake detection that runs entirely on-device — every capture is signed with the phone's hardware-backed key and verified offline. No cloud, no telemetry.

Doc → LaTeX → publishable paper.
A formatting pipeline that turns plain docs into proper, paper-ready LaTeX. Built because every EL and lab at RVCE becomes yet another paper to format.

Pure fun.
A browser mini-golf game with proper physics. The kind of repo that exists because Saturday.
JavaScript · Game · 
Side quest.
Classic Snake, steered with your actual hand. CV + Pygame + a webcam.
Python · CV · Game · 
Productivity, but RPG.
A to-do app that levels you up. Because spreadsheets are boring.

- CS student. Every weekend is a mini game jam — pick a stack, build a thing, see what breaks.
- Shipped games (hand-tracked Snake, MiniGolf, Duo-leveling). Always shipping more.
- Into on-device ML and Android — most recently Vyāyāma, an offline AI coach that runs on the Snapdragon NPU.
- CTFs? Always down. Ping me, I'll drop what I'm doing.
- I like the parts of CS where math, product, and a little chaos collide.
A great codebase is one you'd show a friend at 2am.
Live when I'm playing something. Shows "Was listening to…" otherwise.

| Vyāyāma | On-device AI exercise coach on Snapdragon — recognises, counts, scores & coaches by voice. |
| CoreTex | The repo that earned me my first stars. Still my favorite to come back to. |
| Duo-leveling | A productivity app that treats your to-do list like an RPG. |
Got an idea? A weird side project? A "this probably won't work but…"? I'd love to hear it.
I'm genuinely down to collaborate on:
- Games of any size — jam-scale prototypes, weekend builds, weird controllers, anything
- CTFs — always. Any platform, any difficulty, any time zone. Drop the invite.
- Android / on-device ML apps where the model runs on the phone, not a server
- Productivity tools that don't feel like work
- Hackathons — local, online, last-minute, all of it
- Anything that starts with "what if we just…"
Pitch me here — DM me on LinkedIn, that's the fastest way. Email works too.
No pitch is too small. No idea is too dumb. The worst that can happen is I say "cool, but later."
✨ Built with caffeine, late-night refactors, and a soft spot for retro game vibes.
