Summary
👤
Senior🎓
Top SchoolMatthew Craven is a Senior Solutions Engineer with over a decade of experience bridging EHS domain expertise and technical delivery across enterprise software pre-sales, professional services, and customer success. He has a strong track record winning and delivering major deals (including a £2.5m Siemens engagement) and improving operational processes—earning a Chief Executive Award for customer-journey transformation. Technically fluent, he contributes to open-source projects like SymPy and Haskell's bytestring, focusing on symbolic math simplification, memory-safe byte-string internals and QA, which reflects a rare combination of mathematical rigour and low-level engineering skill. Based in the UK, he pairs hands-on development and QA experience with effective training, demo and POC design, and a knack for turning complex requirements into practical, auditable solutions. Outside work he’s a board-gaming and computing hobbyist with a strong mathematical bent, an interest that informs his careful, test-driven approach to problem solving.

Contributions summary:Matthew primarily focused on improving the efficiency, memory safety, and functionality of the `bytestring` library. Their contributions involved refactoring code, optimizing performance, and fixing memory-related issues within the core data structures and functions. They also implemented and refined several functions, and added related tests. These changes involved deep understanding and modification of the internal byte string implementation, including memory management and low-level operations.

Back-end Developer / QA EngineerContributions:6 commits, 3 PRs, 5 comments in 27 days
Contributions summary:Matthew contributed to the `sympy/sympy` repository by addressing issues related to symbolic mathematics simplification, particularly focusing on trigonometric and exponential functions. They worked on improving the `exptrigsimp` function, avoiding incorrect simplifications for non-commutative expressions and adding tests to ensure the correctness of the simplification process. Further contributions included optimizing C code generation for `Min` functions and improving the accuracy of the `ordinal` function within the utility library.
