Steve James Foncy Arias Arias 👋

Hello 👋 I’m a Senior Frontend Engineer with +9 years of experience designing and building scalable, high-performance frontend systems across web, mobile, Smart TV, and complex enterprise environments. My background spans multiple industries and product types, where I’ve helped teams modernize frontend architectures, migrate legacy systems, and build maintainable UI platforms that scale over time. Key experience & focus areas: • 🧱 Frontend Architecture: Practical application of Clean Architecture and Hexagonal Architecture in real-world frontend systems • 🔄 Legacy Migrations: Migrating large codebases to modern React (17+), improving performance, maintainability, and developer experience • 🎨 Design Systems: Building and evolving reusable design systems and shared UI components across multiple products and teams • 🧩 Modular & Microfrontend Approaches: Experience working with modular frontend and microfrontend architectures (including OpenFront-style setups) • 🚀 Modern Frontend Stack: React, Next.js, TypeScript, scalable state and component architectures • 🧪 Quality & Testing: Unit, functional, regression, and visual testing strategies • 🤖 AI for Frontend: Hands-on use of AI tools and agents to improve frontend productivity, code quality, and UX experimentation Throughout my career, I’ve contributed to projects across human resources platforms, customer support systems, car dealership solutions, streaming services, insurance products, Smart TV applications, and enterprise internal tools. Currently based in Barcelona, Spain, I work as a Senior Frontend Engineer, focusing on modern frontend architectures, system evolution, and long-term maintainability rather than domain-specific constraints. 🎓 I’ve completed a Master’s degree in Software Architecture, focused on IT Management and large-scale system design, delivered jointly by ESAN Business School (Peru) and La Salle (Spain). I’m especially motivated by roles where I can combine technical depth, architectural thinking, and leadership, helping teams transform complex frontend systems into scalable and resilient platforms. 📩 Feel free to reach out: sfoncyarias@gmail.com
