Summary
👤
Senior🎓
Top SchoolIvan Chaer is a Front-end Developer with 13 years of experience designing and shipping Angular-driven interfaces, data visualizations, and custom CMS solutions for high-profile organizations including the European Commission and Belgium’s health sector. He blends strong JavaScript, NodeJS, Python and Drupal skills with a background in web design to deliver efficient, user-focused applications—from D3.js hierarchical visualizations for SNOMED CT to large-scale crawlers that processed millions of pages. At Randstad Digital he applies this cross-disciplinary expertise to digital transformation initiatives, while previous roles show a pattern of building internal tools and high-traffic public sites. Ivan’s work often sits at the intersection of UX and data engineering, enabling complex domain-specific workflows rather than just aesthetic polish. A detail that stands out: he has repeatedly converted manual taxonomy and content tasks into automated pipelines using Selenium and Python, saving organisations substantial operational effort.
