I’m Jonathan Masiello, a front-end architect and engineering lead who loves turning complex product ecosystems into cohesive, user-friendly experiences. Across fintech, banking, e-commerce/media, defense training platforms, and consumer-facing applications, I’ve helped teams modernize interfaces, standardize UI patterns, and ship scalable front-end systems with strong engineering foundations. I work at the intersection of design and engineering—partnering with UI/UX, back-end, and DevOps/SecOps to translate product goals into reusable component libraries, documentation, and CI/CD-ready workflows. I also enjoy applying AI to streamline design-to-code processes (including Figma-to-code), improving developer velocity, and delivering long-lived architectural improvements.…I’m Jonathan Masiello, a front-end architect and engineering lead who loves turning complex product ecosystems into cohesive, user-friendly experiences.
