Top SchoolErik Cunha is a Senior Frontend Software Engineer with 8+ years building high-performance, reliable web applications across regulated and high-traffic environments. He specializes in Angular and React ecosystems, RxJS/NgRx state management, and large Nx monorepos, balancing UX speed, security (PCI-DSS, JWT, RBAC), and accessibility at scale. Erik has repeatedly driven dramatic frontend optimizations—shrinking CSS by 98% and cutting TTI by half—while stabilizing mission-critical payment, healthcare, and e-commerce flows used by millions. He treats releases as a reliability-first discipline, implementing Jest and Playwright test suites, API isolation, and observability to prevent regressions in revenue-sensitive paths. Comfortable in distributed, multi-market teams, he integrates i18n, headless CMS, and real-time WebSocket updates without sacrificing predictability. Beyond code, he builds engineering communities, sharing performance-aware practices that reduce risk and improve developer velocity.
