I help founders and small teams ship SaaS products that actually work in production: billing, webhooks, integrations and the boring infrastructure that breaks when traffic shows up. I work alone, ship when it's done and own the result end-to-end. No handoffs, no account managers, no "let me check with the team." If you want a senior engineer who treats your product like their own, that's what you get.
