FUNCODER

Indie SaaS, building in public

Senior software developer in my sixties with thirty years of shipping experience, now building independent SaaS products with Rails 8 and agentic AI tools like Claude Code and Cursor.

Documenting every build here — decisions, dead ends, rewrites, and the patterns that hold up — so other builders can ship faster.
