Built a monocular visual odometry (VO) pipeline in Rust on the KITTI benchmark. Implemented feature tracking, pose estimation, and trajectory reconstruction, with plotting utilities to compare estimated trajectories against ground truth.
Benchmarked VO accuracy across sequences and experimented with tuning feature detection thresholds and RANSAC parameters to handle motion blur and texture-poor regions. Added demos and visualizations to highlight drift over long trajectories and loop-closure opportunities.

DAC System Design Contest 2022 – 4th place (UBPercept). Built an FPGA-friendly CNN pipeline on Ultra96V2 with quantization-aware training and deployment automation, targeting tight latency/memory budgets.
Led a 7-member team through data curation, profiling, and inference optimization; automated builds and on-board evaluation to iterate rapidly on accuracy–efficiency trade-offs. Documented lessons on model pruning and kernel fusion for edge devices.

Reinforcement Learning driving agent that learns end-to-end navigation from start to goal on 2D road maps. Implemented in PyTorch with a Kivy UI for interactive visualization, reward diagnostics, and episode playback.
Explored reward shaping and curriculum tweaks to improve lane following, collision avoidance, and convergence speed. Logged metrics and rendered trajectories to compare training variants and diagnose failure cases in intersections and sharp turns.
