What I'm looking for

I'm looking to contribute my telecom roaming, firewall, delivery, cloud, charging, mediation, and project-management experience in an esteemed organization where I can further develop my skills while supporting organizational goals.

At Mobileum Technologies, I manage telecom delivery projects valued up to USD 20M, achieving profitability targets above 70% while leading 20+ implementation engineers.

I plan, scope, estimate, and deliver LTE, SS7, GSM, charging, mediation, and network-product implementations. My work includes HLD/LLD documentation, UAT, third-party integrations, stakeholder communication, risk management, and Agile delivery.

Across Ericsson, Tech Mahindra, Nokia, and Mobileum, I’ve designed and supported charging, billing, mediation, OSS/BSS, and roaming platforms. I’ve integrated Ericsson BSCS and Oracle BRM, deployed Nokia Cloud, VMs, Kubernetes, Hadoop, and Red Hat Enterprise Linux clusters, and supported complex northbound and southbound interfaces.

I also automate operational work with Python, Shell, and Ansible, and bring hands-on experience in Linux, Solaris, OpenStack, VNFs, Diameter, and telecom network operations. I’m focused on delivering reliable systems, resolving critical issues, and helping teams meet customer timelines and business objectives.
