Summary
🤩
Rockstar🎓
Top SchoolS Sheppard is a Senior Software Engineer with 14 years of experience building full-stack geospatial mobile and web applications, currently based in Busan, South Korea. He holds a Ph.D. in Computer Science from the University of Minnesota, where his research focused on crowdsourcing and citizen science—informing a pragmatic, user-centered approach to geospatial tooling. At Houston Engineering he progressed from GIS/Web Developer to senior engineer, shipping production systems that blend Python data analysis, ML tooling, and robust web APIs. An active open-source contributor, he’s improved core projects like django-rest-framework and enhanced geospatial stacks such as Proj4Leaflet and django-rest-pandas to better serve client-side visualization and projection workflows. Colleagues rely on him for clean backend design and practical integrations that bridge research-grade analytics with field-ready mobile surveys. His work often surfaces non-obvious efficiencies, such as rendering pandas plots server-side and streamlining projection support for Leaflet, that accelerate data-driven decision making.
