Hi, I'm
JOSEPH AYUK E.
Delivering quantifiable business impact through code.
$70K SaaS in 6 months. 99.9% uptime at scale. Systems that last.
About Me
I'm a Full-Stack Developer and System Architect with over eight years of experience building software that goes beyond functionality. Every system I ship is designed to produce measurable business outcomes.
I architected and shipped Premonio GOALS, a multi-tenant B2B SaaS platform, from a spreadsheet concept to $70K in annual contract value in just six months. At CAMTEL, I led the modernization of five legacy applications to 99.9% uptime and built a network failure prediction tool that reduced Mean Time To Repair by 50%.
I specialise across the full stack: Laravel backends, React/Next.js frontends, PostgreSQL data design, and AWS/Vercel cloud infrastructure. My edge is bringing engineering rigour and strategic thinking to every engagement.
