Services & Capabilities

Fig. 02 — Service schematic

01

App & website development

Mobile apps, web apps, and sites designed, built, and shipped end-to-end — fast, maintainable, and yours to keep.

02

Cloud & data infrastructure

Distributed systems and data pipelines built for correctness and cost — durable workflows, sane service boundaries, and infrastructure that scales without surprises on the invoice.

03

AI strategy

Separating what models can reliably do from what the demo implied. Evaluation, integration, and production guardrails for LLM-backed features.

04

Fractional CTO

Senior technical leadership without the full-time hire — roadmap arbitration, hiring calibration, and honest answers about build versus buy.

Take an ambiguous problem. Figure out what matters.
Build the thing.

Fig. 08 — Point of contact

Bring us your hardest problems.

A first conversation costs nothing. Sometimes the real problem is not the one in the ticket. Write a paragraph about what's breaking; we'll come back with questions worth answering.
