Summary
👤
Senior🎓
Top SchoolLeonardo Merlin is a seasoned team lead engineer with over 13 years of hands-on experience building cloud-native web applications and scalable backend systems, currently driving pricing and prepaid billing at Deel to shrink quote-to-cash cycles. He combines deep AWS and PostgreSQL expertise with a full-stack sensibility—shipping TypeScript/Node.js services while shaping UX and design systems from earlier PWA and government projects. His background spans fintech, logistics, and public sector work, including a notable design system for the Brazilian government and cloud adoption efforts for financial companies. Leonardo is fluent at translating complex domain rules into robust, automatable integrations (for example, streamlining Salesforce workflows at Deel) and enjoys mentoring teams and sharing knowledge through talks and training. A lifelong tinkerer, he traces his roots back to reversing a Delphi app in 2008 and still brings that hacker curiosity to pragmatic, production-grade engineering. Based in Oregon with Brazilian roots, he balances family life with a steady focus on reliable, secure systems that deliver customer value.
