Summary
Wonjae Sung is a Senior Business Analyst and software engineer based in Chicago with four years of hands-on experience building full-stack web applications using JavaScript, Node/Express, React, and MongoDB, and a solid SQL programming background from EJ Basler. He blends technical implementation—APIs, OAuth authentication, responsive design—with analytical rigor honed from years in accounting and finance roles, enabling pragmatic, data-informed solutions. At 100Devs he shipped collaborative, agile projects and reinforced his algorithm skills through a 100 Days of Code challenge, contributing 200+ problem solutions to GitHub. Passionate about teamwork and real-world impact, he now applies that cross-functional perspective at Gallagher, where he bridges business requirements and technical delivery. Outside of work he channels problem-solving energy into rock climbing and collaborative projects, a habit that informs his approach to complex engineering challenges.
