What I'm looking for

I'm looking to solve challenging backend and systems problems, especially in scalable systems, database internals, and software architecture, using the languages and technologies that best fit the problem.

I've contributed core database engine features to MariaDB Server through Google Summer of Code, including a pluggable JSON data type, JSON validation, Mroonga crash fixes, and portable SIMD dispatch for vector search.

I also built CertusDrive, a modular-monolith fleet management platform with real-time tracking, heavy-vehicle routing, PostgreSQL/PostGIS, Redis, Valhalla, and AWS deployment. My backend work spans C#, ASP.NET Core, EF Core, RESTful APIs, JWT authentication, clean architecture, and low-level C/C++ systems programming.
