My name is Roy Ward. I specialize in writing highly optimized code.

I have expertise in optimization, algorithms, data structures, compilers, microprocessor architecture, assemblers, operating systems, number representation, concurrency and compression. I have over 20 years of full-time experience building high performance and low memory solutions, resulting in 12 US and 7 international software patents.

I have a deep understanding of what is going on at all levels, from digital circuitry, CPU design, assembly, higher level languages, data structures, all the way to compilers and operating systems, and I apply this multi-level understanding to everything I do. I also bring to bear my strong mathematics skills which help direct me towards a highly efficient solution to whatever problem I am working on.

I am currently seeking interesting and challenging work using these skills.

This is a portfolio website for some of the projects that I have been involved with. Like everything in life, it is a work in progress.

Work and views presented here are my own.

Note About blog postings: I plan to release a new post approximately every two weeks while I am between jobs, although I expect the frequency to reduce once I am employed. Here are some notes about how I select topics. Next up: ‘Lists of Lists of Tiny Things’, ETA 2024-04-23
