Doby’s ESA Pyxel Logs
Hi, I’m Doby. This page documents my ongoing contributions to the ESA Pyxel open-source project. My work focuses on improving clarity, robustness, and developer experience across Pyxel’s configuration, validation, and error-handling layers. The logs and write-ups here reflect real merge requests, design decisions, and exploratory work, serving both as a personal development record and as transparent documentation of my contributions to the project.
