Software Performance & Scalability Architect

Decades of programming. Solid computing system fundamentals. Problem solving. Brainstorming. Prototyping. Communication. Technical team lead. Software architect. SRE-ish. Author of cheatsheet on Software Performance & Scalability. Former Orbitz/Cheaptickets senior engineer on core tech. Tech research, due diligence and consulting for US State Department, to help bolster national/allied public APD defenses. Indie game engine & personal tool creator since childhood. Built & ran small computer game biz years ago. Wrote, shipped & sold a zombie apocalypse sim a decade ago, directly to the public. For a recent client I did systems programming R&D on mem alloc latency and SEGV resilience, in C for Linux/POSIX, delivering new code, benchmarks, a diagram and a report successfully demonstrating how to upgrade the performance and uptime of their near-RT revenue-sensitive ad-bidding backend. Lately I have 2 side projects in free time: building an educational sim (in Golang) about dire threats to democracy & climate (along with possible fixes); and writing a book on performance & scalability (in public view in my GitHub).
