Summary
👤
Senior🎓
Top SchoolIvan Von Halle is a seasoned systems development advisor with nearly five decades of experience spanning COBOL and RPG on minicomputers to modern web stacks like React and Node.js. After 30 years as a successful freelancer focused on insurance and administrative systems (notably many Visual FoxPro ERP modules), he reinvented his skillset since 2018 through formal full‑stack training at Microverse and multiple SENA courses. Based in Cali, Colombia, he combines deep legacy-system knowledge and migration experience with practical front-end and back-end capabilities, making him well suited for modernization and integration projects. Ivan is pragmatic about starting in developer roles to grow his web portfolio and brings proven client-facing consultancy skills, having sold, deployed and maintained end-to-end applications across Latin America. He is active on GitHub and open to opportunities where his ability to bridge legacy platforms and contemporary web technologies can accelerate delivery. A lesser-known strength is his long track record of building specialty insurance and finance modules, giving him domain expertise many web developers lack.
