Technology Stack

A pragmatic, modern toolchain

We pick tools that survive production — not the loudest tweet. This is the stack we reach for, layer by layer, plus the principles that decide when to deviate.

Architecture

How the stack fits together

A reference architecture for the systems we build — from the edge down to infrastructure, with observability cutting across every layer.

Engineering Philosophy

Why this stack, and not another

Pick boring infrastructure

Postgres before exotic data stores. Kubernetes only when it earns its keep. Boring tech frees attention for the parts that aren't boring.

Tighten the dev loop first

Fast feedback beats fancy tooling. Hot reload, type safety, deterministic local environments — non-negotiable.

Observability is part of the feature

If you can't see it, you can't operate it. Tracing, metrics and structured logs ship with the code, not after.

Buy where it's commodity

Auth, payments, email, transactional databases — we use the best-in-class hosted option unless there's a real reason not to.
