Profile: https://flows.cv/timlenahan

I build software that scales—and I help engineering orgs scale with it. With 10+ years across the stack (front end, backend, mobile, DevOps), I’ve led teams through growth stages: performance and reliability work, refactors, and building process that increases velocity without adding drag. I’ve scaled mobile apps to 5M+ MAU and love turning ambiguity into clear plans, strong ownership, and measurable outcomes.
