About Me

I am a software engineer focused on building high-throughput protocol proxies, concurrent backend services, and robust web applications. My engineering approach emphasizes memory efficiency, non-blocking asynchronous I/O, cache locality, and building fault-tolerant architectures with clear separation of concerns.

Core Languages: Go, Rust, C# (.NET 9), Python, Java, TypeScript, and SQL.
Specializations: Protocol proxying, high-concurrency state machines, spatial indexing, REST/Socket APIs, and automated CI/CD pipelines.
Academic Background: Computer Science & Informatics at the University of Craiova and Politehnica University of Bucharest.

Featured Projects

Minekube Gate Extensions Suite
