Summary
🤩
RockstarDavid Pérez-suárez is a senior research software developer and open-source leader with 14 years of experience, currently serving as CFO for the SunPy project while holding roles at University College London, the Software Sustainability Institute, and The Carpentries. He blends astrophysics domain expertise with hands-on full-stack contributions—authoring data-processing modules like SWavesSpectrogram and enhancing front-end assets for the OpenAstronomy website—to make solar physics data more accessible and reusable. As Summer of Code administrator and long-time Carpentries instructor/trainer, he pairs technical delivery with community stewardship and sustainable research software practices. Based in London, he is comfortable translating complex time-series science into production-ready tooling and documentation. A subtle through-line in his work is craftsmanship: improving RESTful URL structures and responsive UI details alongside robust back-end analysis. His profile reflects a rare mix of scientific curiosity, pedagogy, financial oversight, and pragmatic engineering in the open-source astronomy ecosystem.
