Alexis Ghelardi

At STid, I lead the front-end architecture and platform foundations for multiple business-critical products, defining scalable architectures, shared design systems, and technical standards that support security, maintainability, and UX consistency.

Previously, I was the founding front-end engineer at YJCollective, where I structured and delivered a SaaS platform from scratch. I made key architectural decisions, built a modular design system, and optimized performance and user experience to support complex user journeys and conversion.

At Sweep, I developed core features and complex data-visualization interfaces for a data-intensive SaaS product while owning the marketing website's performance and SEO.

My earlier work spans platform modernization at Optimum Automotive, QA automation at Cityway, and critical internal tools, e-commerce platforms, and CMS solutions at Digitech and E-partenaire. I work closely with product, back-end, UX/UI, domain experts, and end users to turn complex requirements into durable, intuitive products.
