Services
What we do.
Five services. Most engagements begin with one and extend into the others.
End-to-end software development
Web and mobile systems taken from requirements through design and engineering to release.
02Website development and hosting
Marketing and platform sites built, deployed to infrastructure we configure, and maintained after launch.
03Server and email administration
Provisioning, hardening, patching, monitoring and backups for Linux servers. Mail domains configured for reliable delivery.
04Managed self-hosted platforms
Collaboration and messaging platforms on infrastructure you own: updated, backed up and available.
05Ongoing engineering partnership
A standing engineering team for organisations that need software built, extended and run over time.
Products
Software of our own.
The clearest evidence of how we work: products we design, build and run ourselves.
Recruitment, staff records and compliance in one system.
Shift scheduling and timesheets. Runs on its own: add your staff and start scheduling.
Why teelsa
The whole system, handled.
Four things that hold true on every engagement, whatever the size of it.
01
End to end
One engagement covers specification, design, build and production. Nothing is handed off.
02
We run what we build
Systems stay under our care in production: monitored, patched, backed up.
03
Plain communication
Progress, risks and costs reported in plain language, on a schedule you set.
04
Working internationally
