My experience spans across server-side development, Linux systems, and firewall administration, enabling me to design secure, high-performance architectures that can scale efficiently. I’m currently focused on developing high-concurrency, low-latency systems using modern technologies like Go routines, clustering, and load balancing, while continuously improving my DevOps and cloud deployment skills. I’m open to remote or relocation opportunities where I can contribute to global projects, collaborate with talented teams, and continue to grow technically and professionally.
