I build high-performance C++ systems for complex, data-heavy, interactive applications.

I've built performance-sensitive C++ components at DeSmart for complex application workflows spanning more than 10 interconnected software modules. I own implementation, debugging, testing, and production support while improving separation between application logic, data processing, and platform-specific functionality.

I profile CPU, memory, and execution bottlenecks, then resolve issues affecting data-heavy and interactive workflows used by thousands of end users. I've implemented multithreaded and asynchronous processing to keep computationally intensive operations predictable and responsive.

Previously at ELEKS, I developed C++ components for technology and fintech clients, optimized workflows processing millions of structured records, and strengthened regression coverage with unit and integration tests.

I lead code and architecture reviews, mentor developers through debugging and implementation planning, and work closely with product, design, QA, and engineering teams to deliver complex features iteratively.
