What i Do ?
Hi! I’m Cesar Delgadillo, a Senior Front-end Developer and Web Project Manager with 10+ years of experience delivering scalable, high-performance digital solutions.
With a strong background in visual design and UI/UX, I build modern single-page applications using Angular, TypeScript, and RxJS, with expertise in state management (NgRx), RESTful API integrations, and performance optimization with Webpack.
In addition to front-end development, I’m experienced in backend development with Node.js and building robust APIs, allowing me to contribute across the full stack.
I’m fluent in Portuguese and Spanish, have advanced English proficiency, and am open to remote opportunities worldwide.
Let’s connect and build something great!
