Top SchoolJeff Welty is a scientist-turned-software engineer with over 30 years applying scientific analysis to large datasets and building corporate-level applications, notably developing 3D bio-physical forest models and early interactive CAD-like retail kiosks for deck design. He spent three decades at Weyerhaeuser and its Innovis subsidiary where he combined domain expertise in forestry with deep hands-on skills in C, C++, Perl and SAS to optimize applications, tune workstations, and manage hardware and OS environments across Windows and Unix. Renowned for squeezing extra performance out of systems, Jeff’s strengths lie at the intersection of scientific modeling, systems optimization, and practical software delivery. Now retired and based in Federal Way, Washington, he brings a rare blend of field-focused scientific insight and veteran programming craftsmanship that quietly shaped early retail design tools still echoed today.
