Building Reliable Systems That Power Real Business
Backend engineer at Cooperative Bank of Oromia, delivering mission-critical financial platforms with clean architecture and production-grade reliability.
I'm a Backend Developer with hands-on experience architecting enterprise-grade financial systems in the banking sector. My work spans the full backend lifecycle — database schema design, REST API development, microservices, external integrations, and CI/CD deployment.
My most impactful delivery automated the bank's Islamic profit distribution process, cutting processing time from one month to 2 hours for over 13,500 accounts. I've also built payment gateway onboarding modules, microservices-based loan repayment platforms, and health education backends.
I thrive in remote environments with strong async communication, self-driven execution, and a focus on fault-tolerant, auditable systems that scale.
