01 — Manifestowhy we exist
Wedon'tshiptoydemos.Wedesignfrontendspeopleremember,backendsthatdon'tfold,andinfrayouactuallyown.
Typed by default
TypeScript end-to-end. Zod at the seams. Errors that propagate cleanly, not silently.
Observable from day one
Structured logs, correlation IDs, real dashboards. Datadog or Grafana — we wire it up before the first deploy.
Cost-aware infrastructure
Self-hosted MinIO + Postgres + PM2 beats $10k/mo AWS bills depending on the product.
02 — Capabilities
Skills you'd hire individually, under one roof.
Five disciplines, one place.

Product engineering
Greenfield products and serious frontends. React, Next.js, Angular, Vue — typed, animated, performant by default.

Backends & platforms
APIs and services that don't fold under load. NestJS or Spring Boot, PostgreSQL, Redis, observability wired in from day one.

“Pragmatic over trendy — we replaced GCP STT with on-device NLP and cut per-call costs to zero. AWS S3/RDS/ECS with self-hosted MinIO+Postgres on a VPS. Same product, 5% of the bill.”
05 — Arsenal
The stack we ship with.
Primary tools we use in production. Plus a long tail of secondary languages and platforms we draw on when the problem demands it.
