Sébastien Loix is a Principal Software Engineer with 11+ years designing and shipping high-performance, maintainable web applications across startups, public sector and enterprise (most recently at Elastic on the Kibana team). He blends front-end expertise in React/Angular and UX with back-end Node.js and serverless architectures, and is actively expanding into Go. An entrepreneurial builder and maintainer of open-source projects (notably gstore-node), he brings practical experience running an earlier streaming startup and a content platform (Silent drop), which informs his product-minded engineering. His work at Elastic includes concrete UI and index-management improvements to high-profile repos like EUI and Kibana, showing a knack for both polish and scale. Colleagues rely on him for architecture, mentoring and resilient CI-driven delivery in high-pressure environments.
