Hi, I’m Marian Habor, a London-based software engineer with a first-class BSc (Hons) in Computer Science and about a year of hands-on software engineering experience, plus four years of Linux-driven systems work. I thrive in startup environments and bring a strong foundation in programming concepts, security-focused SDLC practices, and Agile methodologies. I’ve built high-performance Rust data ingestion systems, collaborated with product managers, data engineers, and QA to deliver production-grade code, and designed scalable distributed architectures. I enjoy turning complex requirements into pragmatic tools with a focus on security, testing, and latency optimization.
