Custom Software Development

Fractional senior engineering support for custom software projects, from architecture through deployment. We work closely with your team to design, build, and maintain systems you can keep running after the engagement ends.

LLMs, RAG pipelines, and agents are part of our toolkit. We use them where they're a good fit and reach for simpler approaches when they're not.

What You Get

A fractional senior engineer working directly with your team.

Well-Architected Systems

Design decisions grounded in explicit tradeoffs. Systems that stay readable as the team changes and hold up under production load.

Hands-On Engineering

We work inside your repos and write production code. Reviews, pairing, and daily collaboration are part of the engagement.

Testing & Delivery

Automated tests, CI/CD pipelines, and observability are set up early in the engagement. Refactoring and feature work stay safe as the codebase grows.

Ongoing Collaboration

We stay engaged past the initial release to handle iteration, bug fixes, and knowledge transfer so your team can take full ownership over time.
