Projects
Things I've built, from production apps to backend experiments.
Orin
LiveAn AI coding workspace that generates, runs, and previews a whole app inside the browser tab.
Validated four-action AI protocol — write, mkdir, delete, shell — with path checks that reject traversal before anything touches the filesystem.
One adapter across three model providers: Gemini, OpenRouter, and local OpenAI-compatible servers.
WebRTC peer sessions with chat, audio/video, and 256 KB chunked file transfer behind a windowed ACK.
Zenith
In developmentA distraction-free productivity tool for people who want to stay in flow.
Welth
LiveA personal finance app for tracking expenses, setting budgets, and hitting savings goals.
Vexio
LiveA real-time collaborative whiteboard — draw together, see each other's cursors, and pick up after a dropped connection.
Ten drawing element types with live cursors, selections, undo/redo, and admin/editor/viewer roles enforced on the server.
Drag updates throttled to ~30/sec and snapshots debounced to 1.5s, collapsing hundreds of writes per drag into one.
Survives dropped connections with exponential backoff and a 500-operation offline queue that replays on reconnect.
Paywall
ReadyA wallet and merchant checkout platform, built to get the money-handling parts right.
Every balance change runs inside a PostgreSQL transaction with SELECT ... FOR UPDATE row locks, so concurrent debits cannot race.
Amounts stored as integer paise rather than floats, so rounding drift never accumulates.
Nine-model schema covering wallets, transfers, payment links, merchant customers, payments, and settlements.
Meetup
LiveA real-time video calling app with meeting recording, built for small teams.
Video-tube
ReadyA backend-first video sharing platform with the core YouTube mechanics.
Complete domain model: channels, videos, playlists, comments, likes.
MongoDB aggregation pipelines for feeds and watch history.
JWT-based authentication and authorization throughout.
Subscription Manager
ReadyA microservices-based subscription and billing system, built service by service.
Service-oriented architecture with independently deployable units.
Recurring billing, plans, and renewal scheduling modeled explicitly.
Documented in the microservices article series on this site.
