I’m Gobinda Karmakar, a software developer with 3.5+ years of experience building high-performance, network-driven software using C/C++ and Linux. My work involves system-level programming, networking, multithreading, IPC, socket programming, memory management, debugging, and protocol-driven development. I have hands-on experience working with complex production software and solving real-world performance, reliability, and integration challenges. I also have strong domain experience in 5G Core and 3GPP-based telecom systems, working across components such as SMF, UPF, AMF, PCF, UDM, UDR, UDSF and NSSF. I enjoy helping developers understand difficult technical concepts, debug problems, improve their coding skills, and prepare for software engineering interviews through practical, experience-based guidance.
