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 technical lead at Vox Media, where I work on the Chorus team to help bring it to newsrooms across the country. Previously at Vox, I’ve led multiple teams as engineering manager, including the Revenue Platforms team, helping build better advertising tools & products for our networks; and the Performance team, to help make our sites as fast as possible. I was also 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.

  6. gesteves/trebekbot

    An addictive Jeopardy! bot for Slack. Fun fact, after I added this to my work Slack I was told to limit it to a single channel because productivity ground to a halt. (Five years later, the #jeopardy channel is still going strong.)
