What we do.
Five services across the lifecycle of business software. Most clients engage us for one and grow into the others.

New systems & apps
Greenfield builds — web platforms, internal tools, native mobile apps (iOS / Android via Capacitor), and progressive web apps. For businesses with critical or specialised workflows.
-
03
Legacy modernisation
Lifting VB.NET, Classic ASP and COBOL into modern stacks without breaking what works.

How a Tekstak project actually runs.
