Technical interests ¶

building reliable infrastructure
pushing performance and scalability beyond current boundaries
writing understandable and maintainable software

Preferred:
- Python is great for expressing great concepts in little code.
- JavaScript, best served with AngularJS.
- C for the fidgety things. (I'm rapidly replacing C with Rust though.)
- Bash to glue it all together.
Others used:
- C++
- Pawn
