Building ProjectBlock · AI cost & audit

About

Self-taught full-stack & AI developer. I build infrastructure for AI products — cost metering, budget controls, and audit/compliance for LLM calls. Currently shipping ProjectBlock. I care about the boring-but-critical layer most teams skip until it bites them.
