@hernanvalenzuela
Senior C++ engineer building low-latency, high-reliability distributed systems and security monitoring.
ArgentinaWhat I'm looking for
I’ve spent the last 15+ years building backend and distributed systems, from telecom billing and network protocol work to high-performance platforms across Linux and Windows.
At Wazuh, I’m working on security monitoring and agent-based systems in Linux—focused on reliability, performance, and observability improvements.
Previously, at EmTech I developed a high-performance cloud switch for UDP packet routing with zero packet loss, using C++/Go, DPDK, and parallel processing, plus protocol work for packet loss recovery in distributed environments.
Before that, I built enterprise backend services and integrations at Elipgo Technology and Elipgo-style stacks (C#/.NET Core, ASP.NET, WinForms, Angular, MySQL), and earlier roles covered telecom billing and protocol sniffing, plus C/C++ development on OS/2 with DB2 at Verizon and TCS.
