Jing Guo is a software engineer with 12 years of experience who blends deep mathematical training (MSc in Mathematics from the University of Regensburg) with practical open-source software development. They have contributed substantial back- and full-stack code to prominent projects like SageMath (mathematical algorithms and Arakelov–Zhang pairing implementations) and the Nyxt hacker browser (spell-check, hinting, manual refactors), demonstrating strength in both research-grade algorithms and user-facing tooling. Past roles include research software engineering for SageMath via Google Summer of Code and an internship at Atlas Engineer, reflecting an ability to move between academic research and production code. Jing has a history of diagnosing subtle algorithmic bugs and improving documentation and tests, a sign of careful, quality-conscious engineering. Based in Regensburg, Germany, they maintain a technical blog and public GitHub, signaling commitment to knowledge sharing and reproducible work. An interesting detail: their contributions span niche mathematical functionality (global/local heights, affine maps) and practical browser UX improvements, showing an uncommon pairing of abstract math and pragmatic UI polish.
