About

Software Engineer with 3+ years of experience building production-grade backend systems for Siemens Teamcenter. Specializing in C++, C#, and distributed system design, with hands-on experience developing ITK APIs for CAD/CAM interoperability and delivering end-to-end features across backend services and React-based user interfaces. Experienced in diagnosing and resolving complex production issues, including memory corruption, race conditions, deadlocks, and performance bottlenecks using GDB and Visual Studio. Strong advocate of modern C++17 practices, writing thread-safe, maintainable, and memory-efficient code. Proficient in multithreading, IPC, shared memory, socket programming, and CI/CD workflows with Jenkins and Google Test. Solid grasp of LLD and HLD — from design patterns and memory-safe C++ to distributed systems, consistency models, and replication strategies, informed by Designing Data-Intensive Applications (both editions). Strong problem-solving background with 500+ LeetCode problems solved in C++, backed by deep knowledge of Data Structures and Algorithms. Passionate about building reliable, high-performance software systems and continuously expanding expertise in system design and backend engineering. Currently exploring high-performance backend and systems engineering roles where engineering quality matters. 📩 dev.harshaddhondge@gmail.com
