At MMCY, I led IT support operations, coordinating service delivery, incident prioritization, escalations, and SLA performance. I also managed user access across Active Directory, Microsoft 365, and Microsoft Entra ID.
As an IT Support Specialist at MMCY, I investigated hardware, software, network, and system incidents, and supported Windows Server and Proxmox-hosted virtual machines. I documented firewall and endpoint alert evidence and escalated issues for further analysis.
I developed SentinelFlow, a security analytics application that evaluates configurable YAML-based detection rules, supports event replay, and validates detections. I also built PacketScope for network traffic investigations, with flow reconstruction and evidence-linked forensic reports.
My other security projects include tools for vulnerability prioritization, static Windows PE analysis, and web application security assessment. I hold CompTIA CySA+ certification and am pursuing an MSc in Computer Science – Network and Security at Addis Ababa University.
