I build the infrastructure that moves money, saves communities, and powers the next generation of African fintech. Spring Boot, Kotlin, and systems that scale.
I'm Nelson — a backend engineer based in Lagos, Nigeria, focused on building financial infrastructure for Africa. I specialise in Java/Kotlin + Spring Boot systems with a deep interest in how technology can solve the trust, savings, and access problems that hold African communities back.
A full-stack community savings and micro-lending platform built for Nigeria. Groups save together, the pool earns interest, members borrow — all managed by automated rules, trust scoring, and real payment infrastructure.
A banking dashboard interface with transaction management, analytics, and account overview. Clean UI built for usability.
Contributed to Zummey's platform — a Nigerian product connecting service providers and customers across multiple categories.
Built and maintained backend services powering a Nigerian marketplace platform. Designed RESTful APIs, managed PostgreSQL schemas, and implemented authentication and authorization infrastructure.
Built production-grade full-stack applications including Kolo — a fintech platform with real Paystack payment integration, automated fine detection, trust scoring, and loan management. Continuously shipping, learning, and building.
I'm open to backend engineering roles, freelance contracts, and interesting projects — especially in fintech, payments, and African infrastructure.
