Erastus
Amunwe.
Fullstack engineer building national-scale systems. I design, architect, and ship the whole stack — from infrastructure up to interface.
I build the things
that quietly run
at scale.
I'm a fullstack software engineer with 8+ years designing and deploying enterprise-scale applications. I'm the sole architect of a national platform serving 41,000+ employers and impacting around 450,000 employees.
My work spans the full lifecycle — stack selection, hybrid-cloud architecture, CI/CD, container orchestration, and the front-end people actually touch. I care about systems that hold up under real load and integration boundaries that don't surprise you in production.
