Summary

Active open‑source contributor and maintainer: Kunaal has public GitHub repos (including pinned work and Cartography contributions) and appears prominently in contributor/maintainer listings for Cartography within Linux Foundation/CNCF contexts. github+1
Rapid progression from engineering roles to founder: Public company listings and bios show a multi‑year engineering career at Lyft (multiple promotions to Staff Engineer), a brief technical role at Anthropic, then founding SubImage (YC W25), indicating technical leadership and a focus on productizing internal security tooling. ycombinator+1
