What I'm looking for

I’m looking for a product-driven team where I can build scalable frontend systems, evolve design systems, and deliver clear workflows—pairing React/Angular engineering with strong collaboration to improve operations and UX.

I’m a product-focused Frontend Engineer with 6+ years of experience building scalable web applications and education product interfaces using React, Angular, and TypeScript. I specialize in designing user-centered interfaces, component systems, and product workflows through close collaboration with Product Managers and Designers.

In my most recent role (Product Engineer — Frontend), I led internal management dashboards for an iGaming platform—supporting operational teams with tools for monitoring, configuration, and platform management. I built reusable component structures and UI patterns across multiple product modules, evolved the product design system with consistent implementations, and maintained legacy Angular and React codebases while modernizing architecture using component-driven development, monorepo approaches, and microfrontends.

Earlier, I developed a financial platform for the French accounting sector using Angular, TypeScript, and NgRx within a large Nx monorepo, helping translate complex accounting workflows into clear interfaces while improving usability and performance for large datasets. Before that, I helped take a credit recovery platform from 0→1 using React, TypeScript, and Redux, and I contributed to ERP modernization for the automotive sector by migrating legacy desktop workflows into modern web modules; throughout, I focused on reliable UX, scalability, and long-term maintainability.
