I am Calvin Freitas. I am a Principal Front-End Engineer and web developer. I lived and worked in the Seattle area from 2006 to 2020 and then relocated to Hayden, Idaho.

As a front-end engineer, I build, create, and deliver scalable solutions as a professional software engineer. I have built web applications and UI frameworks one of the largest and highest-traffic retail websites in the world. I specialize in e-commerce and seller website and applications.

I write code in TypeScript, JavaScript, Node.js, HTML, CSS, Ruby, Java, Perl, and PHP to build scalable websites and mobile solutions. I’m an expert at React.js, and I have built several sites using Next.js. I built an app with React Native and Expo.
