Senior🎓
Top SchoolTong Zhai is a GIS software engineer with 17 years of experience blending .NET development, hydrology and hydraulic modeling, and environmental engineering to build decision-support systems for public agencies including the EPA, USGS, and US Army Corps. He has a Ph.D. in Biological & Environmental Engineering from Purdue and a long track record of developing desktop and web GIS tools (ASP.Net Core, Angular, ArcGIS SDK, ArcPy) and optimizing environmental models (SWAT, SWMM, HSPF) using C#, C++, Python and FORTRAN. At RESPEC and AQUA TERRA he led integrations between modeling engines and user-facing applications, implementing optimization routines and dynamic routing algorithms used in flood mitigation and BMP cost-effectiveness studies. Now at Geonamic Systems he continues to bridge scientific modeling and scalable software, with notable expertise in EPA-focused tools and ArcGIS mobile/field data solutions. Colleagues rely on him not just for code, but for turning complex regulatory and hydrologic requirements into practical, auditable systems.
