What I'm looking for

I'm looking to build digital products across web and mobile, contribute to robust APIs and high-performing interfaces, and adapt to new stacks as application requirements evolve.

I build web and mobile products for Les Cadors, Mon-Assistant-Perso, Together, and Ball’n Connect/Firecloud, turning product requirements and UI/UX designs into responsive, production-ready interfaces.

For Les Cadors and Mon-Assistant-Perso, I developed Next.js and TypeScript applications with dashboard pages, authentication flows, Stripe subscriptions, reusable Tailwind components, and an OpenAI-powered assistant for campaign creation and lead research.

At Together, I delivered web and mobile features, built a responsive landing page from designs, integrated APIs and backend services, and contributed to platform architecture and technical decisions.

I’ve also built Firecloud’s React Native mobile application and payment system, maintained websites and blogs, and created Freedly, a freelance management platform for activity tracking, quotes, invoices, and a secure client portal.
