Guillaume De Lazzer is a seasoned software engineering leader with over a decade of experience building and scaling products and platforms across startups, scale-ups, and enterprises in Asia, Europe, and North America. He operates primarily as an Engineering Manager and team lead, combining hands-on architectural judgement with people leadership to grow teams, set technical direction, and own delivery outcomes. His background spans backend, mobile, cloud, and platform work—from launching OnlinePajak’s first mobile app to designing large-scale financial integrations and an AI-driven children’s content product he built end-to-end. He has a track record of turning ambiguous problems into operational systems that balance speed, reliability, and long-term maintainability, and has scaled teams from single digits to 30+ engineers while introducing SRE/DevOps and QA practices. An active tinkerer (3D printing, MTB, TypeScript) and open-source contributor—having improved the vue-tour guided-tour plugin—he’s open to leadership, staff/architect roles, or advisory engagements where engineering closely partners with product and business outcomes.
