Abdulbaasit S.
Backend, Database & Systems Engineer | Rust, C++, JavaScript
I'm a systems-level software engineer specializing in Rust, C++, and low-level infrastructure development. I build high-performance tools that operate close to the metal—from PostgreSQL extensions and database proxies to file system monitors and network protocol implementations. My work spans the full stack from systems programming (FUSE, Wire Protocols, libp2p) to database engineering (PostgreSQL, distributed systems) and backend development with JavaScript/TypeScript. I've delivered production solutions at Meta that reduced debugging time from minutes to seconds, built systems handling over 20,000 concurrent users, and contributed to major open-source projects, including ParadeDB. Whether you need custom database tooling, performance-critical CLI applications, or systems integration work, I create reliable and efficient solutions that scale.
