01 / About

A little about me

I'm Oladipo, a final-year Mass Communication student at the University of Lagos and a backend engineer focused on building reliable, scalable software. I enjoy solving complex engineering problems and turning ideas into products that work well at scale.

I've worked across fintech, e-commerce, and multi-tenant SaaS, from payment infrastructure and background job queues to observability and load testing.

Currently a Backend & DevOps Engineer at zpay. Before that I spent two years at Lunix POS building a multi-tenant POS API serving 500+ stores, and built payment and infrastructure systems at Scelloo Technologies and VetaCloud Technologies.
