Open source, with a paper trail.

A contribution-focused view of two codebases I worked in: FixNearby during ELUSoC 2026, and Open Connect / Cortex AI. The records below are curated from authored branches and commit history in my forks.

MERN hyperlocal services platform

Made everyday service workflows portable, observable, and easier to trust.

Full-stack contributor

On my FixNearby fork, I worked across the React client and Express/MongoDB server. The largest slice was a set of export and continuity tools—worker contact cards, booking calendars, comparison CSVs, civic-issue GeoJSON, and recently viewed workers—alongside runtime and authorization guardrails.

Portable workflowsTurned records into useful files

Added browser downloads for vCards, iCalendar bookings, worker-comparison CSVs, and civic-issue GeoJSON. Each utility is small, testable, and attached to the screen where the data is already being reviewed.

User continuityKept the last six workers close

Added bounded, de-duplicated recently viewed worker history with a local-storage fallback, so returning to a useful profile does not require a new search round-trip.

Operational resilienceMade the server easier to run and debug

Added health/readiness endpoints, a graceful shutdown lifecycle, and request correlation IDs. Together they give deploys and incident logs clearer boundaries without introducing another service.

Trust + accessClosed high-friction edges

Contributed issue-status authorization, profile/login/password validation, a shared Socket.IO origin allowlist, accessible loading states, and mobile navigation fixes.
