Bookworm reading tracker — dashboard and reading stats

Bookworm

Cross-platform reading tracker with stats, streaks & a premium tier.

A full reading companion — track books, log sessions, build streaks, join book clubs, and dig into advanced reading stats. It ships to web and mobile from a single TypeScript codebase, with a Stripe-powered premium tier and 682 automated tests guarding every release. I self-host it on a Raspberry Pi behind a Cloudflare Tunnel — owning DNS, reverse proxy, TLS and uptime end to end, with Sentry watching production.

About

I'm a senior full-stack engineer and tech lead with 17+ years shipping Node.js, TypeScript, React and AWS platforms in production. I've led teams of up to six engineers, drove a 60% throughput gain at a fintech handling 10,000+ transactions a day, and built a proprietary LMS from scratch that grew past 60,000 users.

I work end to end — database schema, APIs, cloud infrastructure, and a mobile app live in the store — mostly in TypeScript, with a bias toward clean architecture, real test coverage, and production observability. Off the clock I ship my own products; two are live and in daily use. Currently open to senior full-stack and product-engineering roles.
