Summary
Márcio Júnior is a seasoned JavaScript developer with a decade of experience building front-end and full-stack applications across startups and enterprise teams in Brazil. Currently at Bryntum, he specializes in modern front-end stacks—React, TypeScript, Vue—and has led teams as a technical lead, shipping products from mobile React Native apps to complex BPMN tools. His background includes roles in UI engineering, migration of legacy front-ends, and end-to-end systems involving Docker, Kubernetes and PostgreSQL, reflecting strong practical knowledge of production-grade architectures. He holds advanced studies in computer science and has pursued postgrad specializations in testing and data analysis, signaling a focus on quality and data-informed decisions. Not obvious from titles alone: he’s frequently worked on cross-domain platforms (podcasts, food delivery, agritech, payment systems), which has honed his ability to adapt UI patterns to diverse business needs. Based in Paraná, Brazil, Márcio blends hands-on coding with mentoring and backlog ownership to consistently deliver polished, maintainable front-end experiences.
