We build the software your roadmap keeps promising.

Senior engineers embedded with your team to design, build, and ship products that hold up in production.

Built for teams at Cartwell Bramwell Ferro Instrument Northfield Palisade

Six disciplines, one team

We don't hand you off between departments. The same people who scope the work build it and stay on when it ships.

Web Development

Product-grade web apps in React, Next.js, or whatever your stack already runs on.

Mobile Apps

Native iOS and Android, or one Flutter codebase when the budget calls for it.

Custom Software

Internal tools and platforms built around how your team actually works.

Cloud & DevOps

Infrastructure, CI/CD, and on-call runbooks that don't page you at 2am.

Product Design

Interface and interaction design that survives contact with real users.

Consulting

Staff augmentation and technical advisory when you need senior hands, not a headcount.

How an engagement runs

01

Discover

Two weeks scoping the actual problem, not the ticket someone wrote about it.

02

Design

Architecture and interface decisions reviewed with your team before code exists.

03

Build

Weekly demos against working software, not a burndown chart.

04

Ship

Staged rollouts with rollback plans, because the first release is rarely the last.

05

Support

A handoff document your future hires can actually read.

Selected work

A handful of the systems we've built and still lose sleep over.

Cartwell Logistics — real-time route planning

Replaced a spreadsheet-driven dispatch process with a platform that re-routes 340 trucks as conditions change, cutting late deliveries by roughly a third in the first quarter.

"Kestrel didn't just take a spec and disappear. They pushed back on scope in week one and saved us three months."

"The team embedded like they'd been here a year. Their code review comments still teach us things."

Have a system that needs building, or one that needs saving?

We take on a limited number of engagements each quarter so every one gets senior attention.
