STACK · TECHNOLOGIES
The tools we build with.
We're not married to any tool. We pick the right stack for each product, with a strong bias for TypeScript, edge-first and zero-runtime when possible. Here's what shows up most in our repos.

ENGINEERING PRINCIPLES
01
End-to-end type safety
From DB schema to component. The earlier the error shows up, the cheaper it is.
02
Edge-first
Low latency, zero cold-start. Compute close to the user.
03
Intentionally boring tech
Postgres, Redis, REST. Innovation belongs to the product, not the infra.
04
Zero-runtime CSS
Tailwind 4 + tokens. Small bundle, fast render, consistent design.
05
Observability from day 1
Structured logs, traces and error tracking before first deploy.
06
Artisanal code
Every PR is reviewed. Every feature has an owner. Zero vulnerabilities, always.
