Senior Software Engineer
Senior software engineer in London. Eleven years building event-driven backends, observability, and cloud platforms on AWS and GCP. Now at Collinson, working on the external APIs platform behind airport-lounge access and card-membership perks. Before that I was the primary developer of a production CRM integration platform — Pub/Sub, bidirectional Salesforce sync, OpenTelemetry — at Syntiqa.

What I'm building
Lifters Club
Not a workout tracker — a training decision engine. Takes your training history and produces seven kinds of next-week calls (load progression, deload, missed-session recovery) with auditable reasoning attached to each. Turborepo across a Hono API, a Next.js web app, and an Expo mobile client.
- Turborepo
- Hono
- Drizzle
- Next.js
- Expo
Games Night
A real-time multiplayer party-games platform — the kind of thing you load on a TV when friends are over. NestJS + WebSockets backend, React/Vite SPA frontend.
- NestJS
- WebSockets
- React
- Redis
Animeroll
A personal anime watchlist that produces shareable, Letterboxd-style cards. Shares are immutable artifacts — a snapshot of cover, score, and status is frozen at link creation, so updating your rating later doesn't change what the recipient sees. Next.js 16, Drizzle on Turso (libSQL), Jikan for metadata.
- Next.js 16
- Drizzle
- Turso
- Jikan
Pim Shop
A single-product Stripe bookshop for Pim Wangtechawat's debut poetry collection — All These Poems Are About Love. Lives in a small monorepo with a shared brand package the upcoming author site will reuse.
- Next.js
- Stripe
