AV-Policy-Lab
Closed-loop reinforcement and imitation learning for autonomous driving in nuPlan simulation. Developing behavior cloning, a MILE-style world model, and VLA-conditioned policy baselines evaluated on PDM-Score metrics. DDPM and DDIM built from scratch in PyTorch. Training loss from 0.75 to 0.032, 100x inference speedup with deterministic sampling. Running on HPC A100 via SLURM.

Laksh.ai
Won the AI Prototype to Product Hackathon (March 2026). Production biomechanical pose estimation pipeline for real-time sports analysis. Benchmarked MediaPipe, RTMPose, and YOLOv10 on a custom motion dataset for 8D kinematic fingerprint extraction. Deployed via FastAPI with ChromaDB vector search for athlete similarity matching.

ViT from Scratch
Vision Transformer built from scratch in PyTorch for bi-temporal change detection on Sentinel-2 satellite imagery. Patch embedding, multi-head self-attention, and transformer encoder blocks with no pretrained weights. Benchmarked across IoU, F1, Dice, precision, and recall to map architecture tradeoffs.
