Hire Me

Charlie Malmqvist

I build small, fast, practical software with care for how it feels to use.


What I Do

I take on contract and freelance work for software that needs to be fast, direct, and built by someone who cares about the craft.

I am strongest around systems programming, tooling, games, rendering, compilers, file systems, reverse engineering, and low-level application work.

Most of my work is in C, but I have worked across system-level languages and multiple platforms.


Good Fit

  • Performance-sensitive tools and applications
  • Native desktop software
  • Game engine, rendering, and tooling work
  • Compilers, code generation, and custom languages
  • File system, search, indexing, and data processing work
  • Debugging, reverse engineering, and weird technical problems
