Regional independence at global scale

Split a single global system into regionally independent applications with separate SQL databases, storage tables and blobs, so each region can scale and operate on its own.

Global hearing-technology manufacturer, 2021 to present

Distributed team leadership

Led an engineering team across the United States, Denmark, Poland and India, and raised code coverage with SonarQube quality gates.

Public-sector e-permitting

Developed and maintained a state environmental agency's e-permitting system for the Idaho Pollutant Discharge Elimination System (IPDES) program.

Software firm in Houston, Texas, 2020 to 2021

How we work

Built for scale from day one

Capacity planning, load testing and monitoring are part of the build, not a fix after launch.

Accessible by default

We build to WCAG 2.2 AA, the standard behind Section 508. This website is built and tested the same way.

Quality checks on every change

Automated builds, tests, code-quality gates and dependency updates run before anything reaches production.

Direct access to the engineer

You work with the person who designs and builds your system, from the first requirement to handoff.
