Cinthia Elizabeth Villalejos Zamora 👋

Bienvenidos! 🌟 I am a Senior Frontend Engineer, Data Visualization Specialist and Open Source Maintainer with 7+ years of experience architecting high-performance web applications. Currently I serve as a Subject Matter Expert (SME) for a Fortune 100 technology company, where I bridge the gap between complex data and actionable insights. My focus is on architecting custom rendering engines and optimizing Business Intelligence platforms for massive scale. My engineering philosophy is simple: Data is just numbers until you give it a shape. Beyond feature development, I act as a Lead Open Source Maintainer for internal visualization libraries. In this capacity, I drive the technical roadmap and ensure the stability of our ecosystem. I actively review contributions from global teams, maintain backward compatibility, and streamline the Developer Experience (DX) for hundreds of internal engineers who rely on our tools. As a remote-native engineer, I have logged over 1,500+ hours of cross-cultural collaboration. I thrive in distributed teams, creating the documentation and CI/CD workflows that make asynchronous development seamless. 🚀 Core Competencies: ✅ Open Source Governance: Library maintenance, Semantic Versioning, API design, and managing contributor workflows. ✅ Data Visualization: Expert in D3.js, HTML5 Canvas, and Recharts for rendering large-scale datasets. ✅ Frontend Architecture: Scalable React patterns, State Normalization (Redux/Context), and Micro-frontends. ✅ Performance Engineering: Core Web Vitals optimization, Virtualized DOMs, and reducing interaction latency. ✅ Bilingual Communication: Native Spanish/English speaker effectively bridging technology and global markets.
