About me

Hi, I'm Sinver Aguiló, a Software Engineer with 9+ years of experience building enterprise-class web applications that scale to meet the demands of their users.

My expertise lies in creating robust, scalable front-end applications with Vue.js, React.js and Angular, and I'm also well-versed in building microservices with Node.js and PHP. I've led architecture design for large migration projects — from legacy monoliths to modern client-server and microservices structures — for products like Corotos, NZXT and Crunchyroll.

Throughout my career I've been committed to doing things the right way and getting things done. I thrive in collaborative environments that value innovation and experimentation, and I bring a results-driven approach to every team I join.
