What I do: I take MVPs that you’ve outgrown and upgrade them to support the next stage of your growth.

There could be any number of reasons why your current system is holding you back. Wherever you’re starting to feel the pinch, the price of ownership is that you don’t have the luxury of saying “that part’s not my problem” or “I don’t get involved at that level.”

You won’t hear it from me, either.

20 years handling a wide variety of IT roles and projects mean that I can help through the whole process from high-level strategy right down to code, all based on a deep technical foundation.

In the past I've been a network engineer, run large-scale Debian installations doing devops before it had a name, and been responsible for servers in Antarctica. I have experience with a wide range of different Unix tools and technologies, at various levels of the stack. This gives me the ability—and the perspective—to pick the best combination of tools for any particular project, rather than simply treating everything as a nail because all I have is a hammer.

Buzzwords: Debian, Ubuntu, AWS, PostgreSQL, Clojure, Elixir, Perl, Raku, Common Lisp, Rust, Ruby, Go, Arduino / AVR, FreeBSD
