how we work
Senior engineering, without the agency overhead.
Led by senior engineers
Architecture and direction are set by experienced engineers, with code review built into the workflow rather than bolted on at the end.
Full ownership
We take features from architecture through development, QA and cloud deployment. One team, accountable for the whole thing.
Quality assured
A dedicated QA engineer supports release quality on every engagement, with functional and regression testing before you ship.
Aligned with your hours
We keep working hours that overlap UK business hours and your partners, so feedback loops stay short.
Honest rates
Senior engineering without the agency markup. We keep rates well below the market while holding the quality bar high.
Support around the clock
Technology never sleeps. Once you are live, help is a message away whenever you need it.
