Built a full-stack sensor list web app that replaces Excel tracking for multiple lunar lander programs. A tree structured device hierarchy where engineers add and manage devices at any depth and define new tables and columns with minimal code changes.

Design: The tables are just two generic data models where the data is self-describing. A versioning system that tracks deltas on each branch with immutable and tagged versions.

Built the founding demo: a sports-betting frontend prototype where users compete against each other instead of the house. Pick players, bet the over/under head-to-head against an opponent, and the winner takes the pot.

Design: Built just the frontend against a fake data layer so we could present a demo and get feedback from investors.

Inventory management for a nonprofit supplying school materials. Developed full-stack undo functionality for inventory movements and built the storage locations routes with Zod schema validation. Also built the main dashboard. Collaborated on a team of 9 students with a PM, EM, and designer.

Design: Did not define data models twice. Instead, used Zod to validate data at the API before it causes problems downstream.

Trained and validated object detection models on 200+ annotated medical images. Built the pipelines for training, testing, and loss tracking. Evaluated performance with precision, recall, and mean average precision across multiple IoU thresholds.

Design: Instead of hardcoding one model, I used YAML configs feeding a single model factory so comparing different architectures is a minimal config change.
