Work Experience

Founder and Lead Developer

2016 - PRESENT
Red Pixel LLC
  • Worked with startups and web agencies to define their technological needs, address them according to their timeline, and become part of their go-to people when they need someone fast and reliable.
  • Developed a web app that connected to the client's Shopify store so users could create and buy personalized nail polish colors as part of a marketing campaign. Thanks to this, sales increased more than 20% over the following year.
  • Revamped the web presence of a health products startup by migrating their eCommerce store to Shopify and their marketing site to Contentful as part of their redesign project, which increased sales by 15% over the following months.

ORLY Color Labs
A Vue-based web app that allows users to create a personalized nail polish color based on a database of inspirational images or images uploaded by the user. I connected the app to Shopify using their API so that when users reach the final step of the creation process, they can buy it via the Shopify checkout experience.

I was the sole developer in this project, and I must say it was a very challenging but fun assignment.
