Summary
👤
Senior🎓
Top SchoolHans Terlouw is an independent software designer and developer with roots in the 1960s who has spent decades building scientific and astronomical software, notably as a key designer of the long-lived GIPSY image processing package. Comfortable across eras of computing, he programs primarily in Python while authoring performance-critical C extensions and has experience from Algol-60 and assemblers to modern Unix/Linux toolchains. His work spans multi-dimensional data structures, event-driven UIs (X11/Qt/PyQt), and world-coordinate and non-linear fitting libraries used in astronomy, including the Kapteyn Package. Currently focused on upgrading GIPSY’s data structures to handle APERTIF-scale datasets, he combines deep legacy knowledge with pragmatic modern engineering. An interesting detail: he implemented image interpolation with pseudocolor in PostScript and continues to favor Linux as his primary development environment.
