The Engineering Stack
How we ship.
Opinionated defaults, justified deviations. The tools, the rationale, and the edges where we'd choose differently.
We pick boring, well-operated technology. Every choice below has a written rationale; every deviation from these defaults requires a documented reason.
Frontend
Next.js 16 + React 19
Server Components, partial prerendering, edge runtimes. TypeScript end-to-end.
Backend
FastAPI + Postgres
Async Python on FastAPI, Prisma for the ORM layer, Neon Postgres in production.
Infra
Vercel + Railway
Vercel for frontends with edge functions; Railway for the API services and background jobs.
Mobile
React Native + Expo
EAS Build, EAS Submit, EAS Update. OTA hotfixes and staged rollouts as standard.
UI
Tailwind v4 + Radix
Tokens-first design system. Radix primitives for accessible components.
Motion
GSAP + Lenis
Production-grade scroll and timeline animation, performance-budgeted on real devices.
