An accessibility agent that isn't allowed to grade its own homework.

Scans a live page, proposes a context-aware fix for one of four issue types, applies it, re-scans to confirm the violation actually cleared, and retries once with the axe error as feedback before failing honestly.

The model only makes judgment calls. axe-core owns detection and verification. Deterministic contrast fixes sit in the pipeline as a control case, and they caught two real bugs I would otherwise have shipped.

Document Q&A that has to survive two retrievers before it answers.

Postgres full-text search and pgvector run side by side, and reciprocal rank fusion merges the two rankings. A passage has to place well on keyword match and on semantic similarity before it gets cited.

The unglamorous half: PDFs are byte-validated before parsing, requests are rate limited per IP, there's a global daily cost cap so a bad day can't become a bad bill, and uploads delete themselves after thirty minutes.

A publishing platform with the boring parts done properly.

Rich-text editor, infinite feed, threaded comments, likes, bookmarks, follows and in-app notifications. Frontend, backend and deployment, all mine.

The auth surface is the part I'd point at. JWT sessions, Google OAuth with account linking, email verification and password reset on single-use expiring tokens. Auth endpoints return the same response whether or not an account exists, so you can't use them to find out who's registered.

Notifications are created server-side on engagement events and isolated on purpose. A notification failing never breaks the like or comment that triggered it.

Cafe discovery for Jaipur, ranked so new places can't game it.

44 Jaipur cafes drawn from a public Zomato dataset, with natural language search. GPT-4o-mini parses the query, Gemini takes over when it doesn't.

Ranking is a Bayesian weighted score rather than a raw average, so a cafe with four five-star reviews doesn't outrank one with two hundred good ones. Custom pixel-art interface, built and deployed solo.

The official site for an international academic conference.

Multi-page site for a conference at Manipal University Jaipur, with scroll-triggered animations and responsive carousels, serving attendees and organisers.
