Just chillax man, keep your processors cool.

I'm Apoorv—an engineer and systems architect obsessed with what happens beneath the abstractions. I design software from first principles: from custom C/NDK media engines on ARM to distributed edge clouds and deterministic AI. No agency fluff, no fragile wrappers—just deep engineering craft and systems built to endure.

Engineered an independent YouTube streaming client (Divube) directly against the InnerTube protocol with custom Media3 DefaultLoadControl (1.5s start trigger, 200MB LRU DASH chunk cache, SponsorBlock auto-skip) and pruned NDK binaries to shrink the APK from 224MB to 17MB (-92%). Paired with YRB, an on-device 4K stream extractor that cross-compiles Python, yt-dlp, and FFmpeg directly onto the phone's ARM processor ($0 cloud server cost).
