C++20 limit-order-book matching engine with price-time priority and GTC/IOC/FOK/market orders, fed by a zero-copy ITCH parser over a lock-free SPSC ring with an mmap write-ahead journal. Fuzz-tested and sanitizer-clean, with byte-identical crash recovery. Hit 23M orders/sec at p99 < 90ns.
High-performance cache server with epoll multiplexing, 8-thread worker pool, 16-shard concurrent storage, lazy + active TTL, LRU eviction, and AOF persistence with crash recovery. Achieved 41K ops/sec with p99 < 500µs.
Hands-free reading app for motor-impaired users via blink detection. Tracks 468+ facial and 40+ eye region points using ML models. Achieved sub-1s responses and 94% accuracy.
Tax-agent app handling 25+ dialogue flows for scenario-based queries. Prompt-engineered with 1,000+ prompts via Vercel SDK and Next.js Edge Functions. 30+ financial outputs for personalized simulations.
