Message

At ADIU Communication PLC, I build and maintain a production-grade payroll platform with automated processing, attendance synchronization, RBAC, approval workflows, reporting, and secure APIs.

I also designed central authentication and company-registration microservices that provide a unified login layer across ADIU Payroll, EDM, OKR, Recruitment, and other enterprise services.

Previously at Yene-Chinet, I led backend development for a shipment and logistics platform, delivering REST APIs, real-time tracking, driver matching, background jobs, payment and mapping integrations, and Flutter features for driver and shipment workflows.
