Approach

Find the shortest path to software that ships.

We start by separating what is working from what is blocking the product. Then we modernize, rebuild, or automate only where it moves the business workflow forward.

01

Audit the system

Map the product, codebase, data model, and workflow constraints before choosing the fix.

02

Choose the path

Decide what to keep, what to rebuild, and where Rails, Next.js, or AI will actually help.

03

Build in slices

Ship focused improvements with clear interfaces, tests, and enough structure to keep moving.

04

Release and learn

Launch, observe usage, and tighten the product around real behavior instead of assumptions.

Signals

Senior product engineering without the handoff.

Senior, founder-led delivery

Direct accountability from diagnosis through production.

Rails apps, old and new

Legacy modernization, greenfield builds, and systems that need care.

Full-stack Next.js builds

Interfaces, dashboards, and customer workflows built end to end.

Practical AI automation

LLM features, retrieval, and review loops tied to real work.
