Kofi Mensah

Backend Developer

I’m Kofi, and I build the systems that run behind the scenes—the ones nobody notices until they break (and mine don’t break). I specialize in custom booking systems, payment integrations, and API development for service businesses that need bulletproof reliability. Over 310+ clients across 46 markets trust my code to handle high-volume booking flows without conflicts, process payments securely, and integrate with complex CRM systems seamlessly. My guarantee is simple: zero booking conflicts, zero downtime. From enterprise clients in New York to HVAC companies in Phoenix, I architect backend systems that handle whatever volume you throw at them. Clean code, thorough testing, and an obsession with edge cases—that’s how I work.
