About Jatin

Software Engineer focused on building high-performance systems using modern C++, with expertise in networking, concurrency, and Windows internals. Currently at Zscaler, working on Windows-native security platforms. I design and develop low-latency client systems, scalable client-server communication, and multithreaded components using technologies such as Win32, COM, C++/WinRT, and WinUI 3. My work involves building real-time event delivery systems, persistent WebSocket communication over TLS, and asynchronous workflows that improve responsiveness and system throughput. I regularly work on debugging production issues, optimizing performance, and designing modular, testable architectures. I have strong experience with IPC, distributed communication patterns, and low-level system design, and I enjoy working close to the OS and runtime. Outside of work, I contribute to open source (Mir Display Server) and actively practice data structures, algorithms, and system design. Interested in distributed systems, OS internals, and performance-critical backend infrastructure. Open to opportunities in systems engineering and backend infrastructure.Open to remote, India-based, and international roles Worldwide (relocation/visa sponsorship required).Contact: d••••••••@gmail.com
