What I'm looking for

I am looking for a challenging role that fosters innovation and growth in telecom technologies.

I am a Telecom Solution Architect with over 15 years of experience specializing in 5G Core, VoLTE IMS, EPC, and Cloud technologies. My expertise lies in end-to-end solution design, deployment, and integration across global projects, where I have consistently driven customer satisfaction and technical leadership. I have contributed to the field with two Internet Draft submissions on 5G dual connectivity, showcasing my commitment to innovation.

Throughout my career, I have held significant roles at leading companies such as Nokia and Mavenir, where I led the design and implementation of critical telecom solutions. My technical acumen extends to tools like OpenStack, Kubernetes, and various CI/CD practices, allowing me to effectively manage complex deployments. I am passionate about continuous learning, particularly in areas like SDN, Pen testing, and Cybersecurity, which I believe are essential for the future of networking.
