FlashCache – High-Performance In-Memory Store C++20, Linux Epoll, Zero-Copy GitHub Jan 2025

• Implemented a single-threaded, event-driven Redis-compatible key–value store using Linux epoll (edge-triggered), focused on low tail-latency for read-heavy workloads.

• Built a zero-copy RESP protocol parser using std::string view, completely eliminating heap allocations along the request parsing path.

• Designed a custom linear arena allocator to bypass malloc/free, improving L1/L2 cache locality and reducing allocation latency by 95%.

• Benchmarked on Fedora Linux (Ryzen 5 5600H), achieving 760K requests/sec for GET workloads. Live Strategy Backtester C++20, Event-Driven Architecture GitHub July 2024

• Developed a modular trading engine using an Observer pattern and custom EventBus, achieving sub-microsecond order processing latencies.

• Optimized trade execution pipeline to 324ns average latency (p99: 1.3µs) for market event processing by enforcing zero-allocation paths during runtime.

• Implemented a custom CSV parser with object pooling to efficiently process large historical datasets.

• Integrated simdjson for high-throughput JSON parsing and added unit tests using GoogleTest. Education
