A long light wood conference table in a bright office with black mesh chairs, stacked notebooks, and a black desk lamp, while cascading green digital code glows down from the ceiling in the center.

Who we are

Big O Technologies is a custom software consultancy. We design, build and maintain bespoke systems for teams that have outgrown off-the-shelf tools.

We start with your operations, not a stack. Then we choose the architecture, write the code, and stay on to run it.

What we build

Three ways we work with teams, from first scoping to long-term support.

Six white espresso cups in a row on a concrete counter, the steam from all six braiding into one neat rope rising straight to the ceiling

Scoping before code

A candid read on your requirements, your constraints, and what to leave out.

Delivered to the agreed plan

Architecture, development and testing run against milestones we both signed off.

Owned after launch

Monitoring, fixes and changes handled by the team that wrote the system.

Software that outlasts the tool it replaced.

Bespoke systems, scoped and built by a small senior team.
