I’m a backend engineer specializing in high-performance systems using Rust and Node.js, with a deep interest in distributed consensus and Linux internals. I enjoy building production-ready systems where performance, correctness, and fault tolerance matter.

In my work and independent engineering, I’ve contributed to real-time and decentralized applications. I co-developed UltimateXO, handling game state, player sessions, and WebSocket backend logic, and I’ve also worked on Wasla with TypeScript, NestJS, and Prisma ORM for scalable e-commerce product management.

I focus on practical systems engineering: implementing Linux utilities in C using syscalls, designing RESTful APIs and database schemas with Node.js and Python (SQLAlchemy), and optimizing Nginx load balancing and caching to reduce response latency by 25% while increasing concurrent user capacity. I also contribute to open-source projects like a Rust Redis-compatible key-value server and Solana smart-contract logic in Rust (Anchor).
