I’m a core network & telecom engineer with an electrical-engineering foundation, delivering carrier-grade mobile core projects internationally from Huawei’s Kuala Lumpur hub. I support operators across the Dominican Republic, South Africa, and beyond, including deployments serving 6M+ VoLTE subscribers.

In my current role as a Core Network Engineer, I handle deployment, commissioning, fault diagnosis, and software upgrades. I act as the customer-facing technical interface between operators and engineering teams while integrating 4G/5G EPC, IMS, and packet core solutions.

I’m strong in integration & acceptance testing, signaling and IP networking, and incident resolution, with an OSS/monitoring and reliability/uptime mindset. I also build Python automation scripts to streamline repetitive configuration and verification tasks, reducing manual effort and error rates.

Before this, I completed a Data Center Facilities Intern stint where I gained hands-on exposure to power distribution, UPS, cooling, and environmental monitoring. I’m now motivated to grow across energy-transition tech, IoT/connectivity, cloud, and AI-assisted automation—leveraging my EE background and early infrastructure exposure.
