Web applications
From a first MVP to an established product — design, build, ship, iterate.
Software development
Software built to last, and looked after for the long run.
Sigmabel is a one-person practice building web and mobile applications, cloud back-ends and APIs — and staying on to support them for years, not weeks.
Start a conversationWhat I do
End to end, or exactly the part you need.
Mobile applications
Cross-platform apps for iOS and Android, built and released end to end.
Cloud & APIs
Back-end services, integrations and infrastructure that stay quiet and keep working.
Long-term support
Ongoing maintenance, fixes and small features for systems already in production.
How I work
One person, accountable for the whole thing.
No hand-offs and no account managers — you work directly with the person writing the code. Small, steady delivery, honest estimates, and a bias towards software that's simple to run and cheap to change later.
Several clients have been with Sigmabel for years, which is rather the point: building the thing is the start, keeping it healthy is the job.
The name is Sigma — sums, the whole of the parts — and Isobel, my daughter.
