Summary
🤩
Rockstar🎓
Top SchoolXifong Christian is a London-based software engineer with nine years’ experience, currently building products at Paid after three years at Thought Machine. He holds a first-class MEng in Mathematical Computation from UCL and combines a strong theoretical foundation with hands-on backend and tooling work. His background includes creating Python tooling to map and refactor large SQL stored-procedure estates, reorganising Selenium scrapers, and adding a lemmatization-based tagging system to improve discoverability. As a programming tutor he taught C, Haskell and Java with an emphasis on language paradigms, and as an intern introduced file-locking and versioning for a British Sign Language corpus — evidence of a habit for practical, reliability-focused engineering. He’s known for turning formal reasoning about systems into pragmatic automation that improves maintainability and developer productivity.
