At M-PESA Ethiopia, I build the integration platform used by 100,000+ merchants and partners, including standardized APIs and backwards compatibility for older contract versions. I also built a Spring Boot digital voucher service that replaced an external provider and cut that cost by 70%.
At M-PESA Ethiopia, I built and maintained Spring Boot microservices for core-to-core banking integrations, focusing on failure paths such as timeouts, partial writes, and ledger reconciliation. I designed RESTful APIs for third-party integrations and delivered a national promotion platform that maintained data integrity through peak traffic of millions of transactions per hour.
At Arc.dev, I architected and deployed a multi-tenant SaaS platform on AWS using Docker and Terraform, and built Backend-for-Frontend APIs that cut launch time by about 40%. Earlier, at Safaricom Telecommunications Ethiopia, I built a document management portal and automated security workflows; I also hold an AWS Certified Cloud Practitioner certification.
