systems architecture · software engineering · applied AI

We design, build, and run software that holds up in production — from first diagram to metal.

alpha v0.1 — two engineers, one forge

$ ls ./capabilities

systems architecture

Boundaries, data flows, failure modes — decided before the first commit. We draw the system, then we defend the drawing.

software engineering

Typed, tested, shipped. Boring pipelines, exciting products. Code that the next engineer thanks you for.

saas platforms

Multi-tenant products from zero to production — auth, billing, observability, the unglamorous 80% done right.

applied ai

RAG, agents, evals. Grounded in your data, measured against reality, zero fabrication tolerated — in the model or the pitch.
