Senior software engineer with 12+ years of experience. My main experience is working on collaborative visualization/editor web applications both frontend and backend. My last role was CTO in a startup with 50/50 split between hands-on work and management. I am looking for senior+ software engineering roles especially in systems-level contexts (have some performance profiling/tuning experience and done simple projects in C and Zig) or technical leadership roles.
