Engineering cfire: C++23 Without the Ceremony
Batteries-included C++23 that plays nice with agents. Declare intent cleanly, get auto-linked standard libraries, and keep raw systems performance without fighting C++ toolchains.

Build Info
I'm Guillermo Sandoval (Memo) – a Software Engineer and engineering lead focused on empowering teams to build the least amount of code that achieves human happiness.
Back at Google since 2026 on the Site Reliability Engineering team for Payments, after a year-plus at Duolingo leading the Observability team. Before that, seven years at Google managing debug logging systems, log-based insights, and monitoring metrics storage handling TB/s of data. Over 15 years of experience spanning distributed systems at scale, developer tools, and building solutions for large groups of engineers.
I value technical depth but focus on evaluating what problems are worth solving, system design, and unblocking teams. I believe in open collaboration, challenging assumptions, and acknowledging the human side of engineering.
