Senior🎓
Top SchoolJoel Masselink is a GIS developer and geospatial strategist with 11 years of international development and conservation experience, blending technical depth in FOSS4G, cartography, remote sensing, and data visualization with program-focused delivery for nonprofits and donors. He has led geospatial and data services at Creative Associates’ DevLab and now supports federal and commercial clients—maintaining the SBA HUBZone map and consulting through Rock Creek Maps and Oasys International. His background spans field capacity building in the DRC to building wildlife monitoring systems for Vulcan and Earthranger, showing he can move between hands-on mapping and scalable geospatial systems. Joel’s work routinely bridges proposal design, geographic prioritization, and monitoring & evaluation, making maps a decision-grade asset rather than just illustrations. Based in Rockville, MD, he pairs academic training in GIS for Development and Environment with a playful “geo geek” approach to practical problem solving.
