Top SchoolChristina Sioula is a Scientific Software Engineer with nine years of experience building high-performance, research-driven software from numerical simulation engines to analytical databases. Based in Amsterdam, she has contributed core features to DuckDB—adding regex functionality, INET types and extending its httpfs to read from GCS and R2—demonstrating solid C++ backend and data-engineering skills in a widely used open-source project. Her background in mathematics and experience optimizing linear algebra for Ansys give her a strong foundation in numerical methods and performance engineering. She also automates developer workflows with Python code generation and emphasizes maintainable, well-tested systems. Unusually for an engineer with deep systems expertise, she has hands-on teaching and operations experience dating back to academia and property management, which sharpens her communication and pragmatic problem-solving.
