Nick Gravgaard, senior software developer

I'm a senior software developer with over 13 years of commercial experience and a track record of creatively solving interesting problems for my employers and my own projects (inventing an algorithm now used by Google and a feature in Vim - see softography below). I've worked on a wide range of different kinds of project, including web sites, back-end systems, application software, games and information security. These days my main language is Python but I also know JavaScript, C#, C++, C, Java and Go.

I am a firm believer in using Test Driven Development (TDD), especially when developing with dynamically typed languages like Python. The assurance one gets when code is refactored and every unit test still passes is invaluable.

If you have an interesting software problem you should consider employing the services of my company, Beautiful Code.

Invented the elastic tabstops mechanism for handling tab characters in text files. I have written a package in the Python Package Index (PyPI) and also worked on an implementation in C++ for the Scintilla text widget. The algorithm has subsequently been adopted by Google's Go programming language for formatting code
Invented relative line numbers in the widely used Vim text editor. As with vi, Vim users often need to specify the number of lines an operation should be performed upon, and this feature makes that much easier. Relative line numbers were added to Vim in version 7.3 and can be enabled with :set relativenumber or :set rnu
Developed the WindowLab open source window manager for the X Window System on Linux/Unix using Xlib and C
Coded numerous games (in C, M68k assembly and Blitz Basic) for the Amiga range of computers which made use of the platform's unique video hardware to do some interesting visual effects (techniques used the copper, blitter, sprites, dual playfields, planar and "chunky" graphics). One of these, BombBloke (from around 1993-1996) is available as a zip file or as an adf file. There are screenshots here, here and here
Playtested the commercial games "Worms" (1995) and "Worms - The Director's Cut" (1997) - see screenshots here and here
