Top SchoolLucas Perez is a Lead Software Engineer based in Chicago with nine years of hands-on experience building and scaling mission-critical systems, most notably leading the $1.6B Walgreens micro-fulfillment platform from 0 to production and supporting over a million daily transactions. He blends full-stack engineering, DevOps collaboration, and strong code-quality discipline—mentoring teams, enforcing SOLID principles, and bridging gaps across RunOps, Security, Product, and Directors.
