Systems Engineer specializing in High-Performance Rust, Bare-Metal C/C++, and Zero-Copy Polyglot Architectures.

Systems Engineer focused on low-latency architectures, bare-metal C/C++ FFI, and production Rust backends. ​I specialize in eliminating runtime bottlenecks at the C-ABI boundary—building high-throughput polyglot extensions (PyO3, FFI) and zero-copy memory pipelines for AI/ML inference and SaaS infrastructure. ​Core Stack: Rust (Axum, Candle, SQLx), C++17/23, C23, PyO3, PostgreSQL, MinIO. ​Proof of Work: Creator of FinTally—a pure Rust finance platform evolved from legacy Node.js/Django to FastAPI + PyO3, and ultimately rewritten into a full-stack Rust architecture powered by bare-metal C/C++ native engines via extern "C" FFI.
