Summary
🤩
Rockstar🎓
Top SchoolSergio Manjate is an Operations Manager at NSK Group with nine years of hands-on IT and engineering experience and over a decade of client-facing delivery across banking and FMCG clients such as Standard Bank, Investec, and Danone Southern Africa. He blends technical depth—demonstrated by C++20-focused open-source contributions to high-profile projects like Chromium Embedded Framework and curl—with operational leadership and a customer-first mindset. Sergio has a proven track record of resolving low-level issues (memory/size checks, buffer overflows, platform-specific file handling) while streamlining development scripts and documentation. Comfortable moving between back-end code and client strategy, he is seen as a trusted advisor who anticipates needs and builds lasting relationships. Based in Gauteng, South Africa, he pairs pragmatic engineering instincts with the people skills required to scale IT solutions in complex environments. An interesting detail: alongside managing operations he still actively contributes algorithmic C++ solutions, signaling a rare mix of manager-level oversight and deep coder craftsmanship.
