Things I've built.

Infrastructure-first projects emphasizing performance, scalability, and clean abstractions.

Featured

AutoTA

Deterministic automated grader that ingests 200+ Google Classroom submissions through the REST API, runs JUnit tests, and generates initial grades while detecting missing assignments.

challenge

Containerizing JUnit execution and building CI checks that keep grading safe, repeatable, and reliable across every commit.

JobMatch

Job ingestion and matching system that aggregates postings from 5+ job boards, stores raw data in S3 and normalized records in PostgreSQL, then ranks roles by career alignment.

challenge

Making job search repeatable by combining resilient ingestion, normalized storage, weighted NumPy ranking, and reliable test coverage for new sources.

DermAI

AI-powered skin condition analysis app built at the MTC Hackathon. Users upload a photo to receive instant analysis across 8 condition classes, with confidence scores, severity ratings, personalized advice, and a DeepSeek-powered diagnosis chat interface.

challenge

Significant class imbalance in the SCIN dataset required careful augmentation and stratified splits. Calibrating the AI chat to be medically responsible without being overly restrictive was a real balancing act.
