Services

Build what the business needs. Rescue what the business already depends on.

I work best where software is tied to real operations: bookings, enrolments, admin workflows, devices, reporting, and systems that have to keep earning trust.

01

Build custom business systems

Turn manual workflows, disconnected tools, and business-specific requirements into software your team can rely on.

  • Booking, enrolment, and workflow systems
  • Dashboards, reporting, and operational tools

About jatskie

I fell in love with computers at 8. I still like the practical magic of making them useful.

That curiosity became a career across educational systems, collaboration platforms, recruitment technology, self-service systems, websites, booking flows, enrolment workflows, and hardware-integrated interfaces.

Today I help small businesses and founders build software that fits how their operations really work, and I help rescue older systems that still matter but have become hard to change.
