Rockstar🎓
Top SchoolMaarten Niederer is a data-focused software leader with over a decade of experience at the intersection of asset management and backend engineering, currently leading Data Management chapters at Ortec Finance. He combines deep expertise in financial instrument modelling and production-quality code with hands-on performance tuning for high data loads, often trading functional purity for tangible gains in speed and storage. His background spans consultancy, requirements engineering, SQL/PLSQL development and client-facing support across pension funds and asset managers, and he mentors teams on data transformations, ML, and storage standards. An active contributor to open-source PHP tooling, he has improved developer experience in event sourcing libraries by adding strong typing and snapshotting support—evidence of his inclination to modernize legacy systems pragmatically. Trained in computer science and mathematics with honours from Utrecht, he brings both analytical rigor and practical judgment to complex, production-critical problems.
