Guillermo Esteves

Hello, there. I’m a Venezuelan-American web developer based in Jackson Hole, Wyoming, right in the heart of Grand Teton National Park. I’ve been building websites for nearly 20 years, and I’m currently a full-stack engineer at Vox Media, Inc., where I work on the SaaS team to help bring Chorus to newsrooms across the country. Previously at Vox, I’ve led the aforementioned SaaS team as engineering manager; led the Revenue Platforms team, helping build better advertising tools & products for our networks; led the Performance team, to help make our sites as fast as possible; and worked as a senior front-end engineer at The Verge, helping build a sweet, responsive, better performing site, as well as cool editorial features like Fanboys and The Verge 50.
