Yannick Schetrite

Solo design and build of a point-of-sale tailored to a French fine-craft consignment boutique, ahead of France's September 2026 electronic invoicing law. Strict, auditable backend (Rust, sealed event log, tax-snapshot isolation) paired with a UI meant to be a pleasure to use day after day — accessibility and i18n carried from the first commit, not retrofitted. User- and product-oriented all the way through, from regulatory constraints down to keyboard navigation and semantic structure on a 25k-item virtualized catalog.

Worked on complex product surfaces in healthtech, focusing on clarity, reliability, and accessibility. Built and maintained advanced React/TypeScript components (large data tables, forms, multi-step flows) and improved the overall quality of the UI. Key responsibilities & impact • Developed complex, accessible UI components with strong attention to UX and maintainability • Strengthened testing practices (unit, integration) and improved debugging workflows • Systematically integrated accessibility (keyboard navigation, ARIA patterns, semantic structure) • Collaborated closely with designers, backend engineers, and product teams • Mentored teammates and contributed to code reviews, documentation, and internal best practices

Worked on the POS Lite ecosystem, building accessible and reliable interfaces for partner integrations (delivery, accounting, banking). Key impact • Built complex, strongly typed UI components (tables, multi-step flows, configuration screens) • Designed activation, configuration, and sync flows with clear domain boundaries • Co-shaped API contracts with backend engineers (types, behaviours, edge cases) • Contributed to the Design System (a11y patterns, semantics, documentation, component quality) • Improved debugging and reproducibility across multiple integrations • Active member of the Frontend Guild + regular pair programming in an international distributed team

Contributed to the migration from a Flask + Backbone.js monolith (SQL) to a modern TypeScript-based architecture using Node.js, MongoDB, and Next.js. Built accessible, reusable React components and helped drive the transition from early-stage product to a structured SaaS platform. Key impact • Developed core React/TypeScript components for lessons, activities, and pedagogical flows • Integrated accessibility and semantic quality into shared UI elements • Guided the shift toward a modern, component-driven architecture across the new TypeScript stack • Collaborated with product and design teams to modernize the platform’s UX • Helped establish frontend standards during the transition to a modular architecture

Worked as a consultant on several web projects, mostly focusing on modern frontend development with React and TypeScript. Explored other lightweight frameworks (Riot, Mithril) and contributed to responsive, CSS-heavy interfaces. Key impact • Developed React/TypeScript components in early-adoption contexts • Built lightweight UIs with Riot.js and Mithril.js when required • Implemented responsive layouts, SCSS, and CSS architecture improvements • Introduced progressive enhancement and PWA-oriented patterns on some projects • Wrote a small amount of unit tests and contributed to general frontend best practices • Collaborated with backend teams (Scala) without working on backend logic
