I build systems that meet cameras, electrodes, users, and imperfect inputs as they actually are — AI engineering undergrad @ Amrita Vishwa Vidyapeetham.
gh pr list --author @me --state=all
I contribute upstream where a small, precise change removes a real developer paper-cut — then add the regression test or documentation that keeps it fixed.
78 pull requests merged to date — 51 upstream across nine labs (tabled below), 5 in peer repos, and 22 shipping a production e-commerce build phase-by-phase through PRs (Sree Vartali Sarees — CMS, store, cart, orders, WhatsApp).

ls ~/lab/specimens
| case | friction | approach | proof | stack |
|---|---|---|---|---|
| SPX-01 · MOTION markerless motion capture |
useful mocap lives in laboratories — special suits, special cameras, special rooms | two ordinary camera views → MediaPipe landmarks → stereo DLT triangulation → filtering → joint kinematics | offline-first pipeline, live 3D inspection, real mocap export formats | Python FastAPI React Three.js OpenCV |
| SPX-02 · DECISIONS self-play reinforcement learning |
"the agent learned something" isn't evidence until tested against a known-optimal opponent | Double/Dueling DQN + NoisyNet + prioritized replay, pressured by self-play and a minimax baseline | ships both the learned policy and the sanity check — not just the score | Python PyTorch RL |
| SPX-03 · BIOSIGNALS EEG artifact recovery |
real EEG is eye movement, muscle noise, electrode drift — and somewhere in there, the signal | SVD separates low-rank artifact structure from 14-channel Emotiv EPOC X recordings | denoising as signal recovery, with the assumptions visible | MATLAB SVD signal processing |
| SPX-04 · ON-DEVICE VISION projX OMR grading |
document evaluation usually becomes "upload everything and wait" | capture, bubble detection, key comparison and export all stay on the phone | a complete grading workflow with zero server round trips | Flutter Dart OpenCV |
| SPX-05 · SYSTEMS POSIX file manager |
abstractions hide what the machine actually does | built directly on raw POSIX system calls — every operation mapped to its syscall boundary | know what's underneath your abstractions | C POSIX system calls |
cat calibration.md
Build it from scratch at least once — the magic disappears, the understanding stays.
If you can't reproduce it, you don't understand it yet.
Real data over clean examples — messy input teaches what tutorials hide.
Know what's underneath your abstractions. They all leak eventually.
