In my previous roles, I have extensively worked with C++, developing scalable and reliable software for various applications. I understand the principles of object-oriented programming and have utilized C++ for performance-critical tasks in mobile core systems, ensuring that communication protocols run efficiently while optimizing for network traffic.

When troubleshooting in a mobile core network environment, I focus on a systematic approach. I gather logs and metrics to identify points of failure, analyze them methodically, and isolate issues in either the application layer or within the network stack. Utilizing IP networking knowledge, I ensure that components are communicating as expected, and make necessary adjustments to optimize performance.

I have a solid understanding of 3GPP protocols such as LTE/4G EPC and 5G Core. These protocols are crucial for standardizing communication in mobile networks. They define the technical specifications for connectivity and service delivery, and my experience in dealing with these standards ensures that I can design robust software solutions that comply with industry requirements.

APIs are essential in mobile core development as they facilitate communication between different software components and services. They allow for modular design, enabling various applications and services to interact seamlessly. In my previous roles, I have designed and maintained APIs to ensure optimal performance and ease of integration across the mobile stack.

I have actively participated in Agile development processes, attending daily stand-ups and sprint planning meetings. My experience includes collaborating within cross-functional teams to deliver software solutions incrementally, ensuring that we remain adaptable to changing project requirements while fostering a productive workflow.

To stay up-to-date with the latest technologies in mobile core engineering, I regularly follow industry blogs, attend workshops, and participate in relevant online courses. Being part of tech communities and forums allows me to learn from peers and apply new knowledge to my projects, ensuring that I am always aligned with industry trends and standards.

My experience with DevOps practices includes knowledge of CI/CD pipelines, containerization with Docker and Kubernetes, and automating deployments to streamline development processes. I believe that integrating DevOps principles has significantly improved my efficiency and the reliability of the applications I’ve worked on.

In my last role, I faced a challenging issue with system performance during high traffic loads. I conducted a thorough analysis of the application architecture, identified bottlenecks in the code, and refactored the components to enhance efficiency. As a result, I improved the system's response time significantly, leading to much better user experiences.

I prefer using tools such as Prometheus and Grafana for monitoring mobile core systems, as they provide real-time metrics and visualization capabilities. These tools allow me to track system performance, identify anomalies, and respond proactively to ensure the systems run smoothly.

I am motivated by the challenges and rapid advancements in mobile core development.
