My Story

Why I started Tux Software

After over a decade of experience in enterprise software development and information security, I founded Tux Software with a simple conviction: businesses deserve senior-level expertise delivered directly to clients.

I've seen too many projects fail not because of bad intentions, but because the people making technical decisions were disconnected from the people actually building the software. At Tux, there is no disconnect. You work with me from day one and we will build your solution together.

The name? We just love penguins.

Core Values

  • Honesty over sales — if it's not the right solution, I'll say so.
  • Clarity over complexity — simple, maintainable code beats clever code.
  • Quality and speed — I look to deliver both.
  • Security by default — not bolted on at the end.
