What I'm looking for

I'm looking to lead and build reliable, high-availability systems, ship production AI features, and mentor teams through complex architecture and integration deliveries.

At Kifiya Technology, I lead architecture for IMARA, a multi-portal marketplace connecting funding partners, business development service providers, and finance. I built its modular Spring Boot and Next.js platform, including Keycloak OIDC, organization-scoped RBAC, workflow automation, and AWS ECS delivery pipelines.

I’ve spent 8+ years building high-availability Java systems, including mobile-money microservices at Safaricom Ethiopia that cut API response times by up to 30%, and payment-platform integrations at Pagatech serving 17M+ users. I also ship multilingual LLM-backed learning tools and Telegram bots, with observability and event logging designed to keep production failures traceable.
