Experienced Software Engineer

decades of programming. solid computing system fundamentals. problem solving. brainstorming. prototyping. communication. technical team lead. software architect. SRE-ish. solved hard legacy bugs & shipped over and over again. author of cheatsheet on Software Performance & Scalability. former Orbitz senior engineer on core tech (JVM, perf, ops.) Tech research, due diligence and consulting for US State Dept, 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 (de facto) sys 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 have 2 side projects: * building a real-time Rogue-like edu/adver-game (homegrown engine in Go) about dire threats to democracy & climate * writing a book on performance & scalability (in public view in my GitHub). Challenge me! Give me hard problems. Or let me pioneer or bootstrap a new codebase. Treat me as a very senior and experienced, professional engineer. Use my time efficiently. Let me deliver the BIGGEST bang for the buck, for you, that I can. Life is short. I do have a "No Jerks" rule. And I prioritize on folks who demonstrate how much they value me (not necessarily in $) -- I'll match you in return. I look for culture and personality fit early. Fan of Getting Real
