Summary
👤
Senior🎓
Top SchoolJuan López is a seasoned Software Engineer and Full-stack Developer with 10 years of experience building enterprise-grade backends, mobile apps, and modern frontends across Java, .NET, PHP, Node.js, React, React Native, Next.js and Angular. He currently shapes product experiences end-to-end at Charles River Laboratories, working in monorepos (Lerna/NX), CI/CD (Azure DevOps, GitHub Actions) and a test-first culture (jest/vitest, Playwright). Previously he led small agile teams as a senior full-stack developer and scrum master, architecting trading and consumer finance platforms and mentoring junior engineers. Comfortable moving between system architecture and hands-on implementation, he favors clean code, SOLID principles and user-centered, performant solutions. Based in Spain with a Master in Mobile Business, he pairs deep backend roots with a long-standing passion for mobile and frontend development—so he’s as likely to optimize an API as to prototype a slick mobile UI.
