About me

I'm Yhonaiker Moncada, a software engineer focused on frontend. For 5 years I've been building high-impact web and mobile products, caring about performance, accessibility and the maintainability of every interface.

I'm a Senior Software Engineer at Witi, building scalable solutions with React, TypeScript, Tailwind and Zustand, and integrating NestJS backend services. Before that I built cross-platform mobile apps with React Native and helped modernize systems, migrating them to React, Angular and NestJS architectures.
