Shipped a React checkout component that cut median page latency 28% on a staging cohort of 1,200 sessions by splitting a 180 KB bundle and lazy-loading payment widgets. Wrote Python integration tests covering 46 API routes for an internal billing service, raising line coverage from 41% to 78% before the August release. Paired with a senior engineer to migrate 12 REST endpoints from ad-hoc JSON to typed OpenAPI contracts, cutting client integration bugs filed by QA from 9 to 2 in the final sprint.

Built a sample-tracking dashboard in React and PostgreSQL used daily by 18 lab-ops coordinators, replacing a shared spreadsheet that averaged 6 version conflicts a week. Added indexed SQL views that dropped the slowest report query from 4.8 seconds to 0.9 seconds on a 220,000-row staging table. Documented onboarding notes for three new interns and led a 45-minute code walkthrough of the lab API authentication flow.

Resolved 30–40 student and faculty tickets a week for lab machines, account access, and classroom projectors, holding a 92% same-day close rate across two academic terms. Scripted a PowerShell and Python check that flagged 140 lab PCs missing a required compiler before midterms, cutting walk-up “won’t compile” tickets by about a third. Co-ran a weekend hackathon help desk for HuskyHacks, debugging Git, Docker, and API key issues for 22 student teams.

Led a 4-person team that built a transit-delay map for Boston Harbor ferries, placing 2nd of 38 teams at HuskyHacks Spring 2025. The demo pulled MBTA-style GTFS feeds into a React map used by 310 visitors during judging weekend.
