I’m a Senior Software Engineer with over 8 years of experience building large-scale, high-performance backend systems using Java, Spring Boot, and modern DevOps technologies. I’ve worked on enterprise-grade solutions in finance, energy, telecom, and e-commerce, always focused on clean architecture, scalability, and reliability.I specialize in microservices, distributed systems, and cloud-native development using Kubernetes, Docker, AWS, and CI/CD pipelines. My daily toolkit includes Java, Kotlin, Go, and TypeScript backed by experience with frameworks like Spring Cloud, WebFlux, and Angular.My background includes:

DXC Technology: Building pricing microservices for global fuel and charging networks.

WorkMotion: Architecting finance and invoicing systems integrated with NetSuite ERP.Jumia: Developing and stress-testing payment APIs for JumiaPay’s high-traffic platform.Celfocus & Intercom: Delivering telecom and banking systems used by millions of users.

I bring an engineering-first mindset: testability, performance, and maintainability come before trends. Whether it’s designing a distributed service from scratch or optimizing existing infrastructure, I build software that scales cleanly and lasts.If you need a backend engineer who can handle the full lifecycle from architecture and code to deployment and observability, I’ll make your system robust, reliable, and production-ready.
