// PERFORMANCE_METRICS

Order Matching Engine

Throughput: 100K–1M+ orders/sec
Latency: Microsecond-level processing
Complexity: O(1) insert / cancel / execute
Stress-tested: 1M+ concurrent orders

Lock-Free Messaging

Throughput: 10–20M+ messages/sec
Latency: Sub-microsecond median
Performance: ~15–25× faster than mutex
Cache-line aligned • Zero false sharing

High-Frequency Order Matching Engine GitLab
GitLab Repo
Matching Engine Source
Click to open →

Built a production-grade exchange-style order matching engine.
Handles 1M+ orders with O(1) operations and microsecond latency.
Multithreaded architecture with zero hot-path heap allocations.
Simulates real-world HFT trading infrastructure.

Why this matters: Directly replicates the core engine inside every real HFT and exchange platform.

Lock-Free Messaging Framework GitLab
GitLab Repo
Lock-Free Queue Code
Click to open →

Designed a lock-free SPSC ring buffer using std::atomic.
Achieves 10–20M+ messages/sec with sub-microsecond latency.
alignas(64) cache-aware design eliminating false sharing.
Zero-copy preallocated buffers for maximum throughput.

Why this matters: Lock-free IPC is a critical bottleneck in any low-latency pipeline.

Linux Command Line Shell GitLab
GitLab Repo
Shell Implementation
Click to open →

Developed a Unix-like shell implementing full process lifecycle.
fork/exec/wait • pipes • I/O redirection • job control.
Built-in commands: cd, pwd, ls, history, cp, cat.
Modular CMake build, tested Linux + WSL.

Why this matters: Proves deep OS-level knowledge essential for systems and HFT roles.
