Projects I've worked on in my free time. Learn more about me here.

Sergio's Collection

1999-2003, 2020 - Present

One day, I was cleaning and found my pokemon collection from when I was a kid. Looked at prices and decided it was time to sell some of the collection. Ended up turning it into a business and also got back into collecting. Now I collect, buy, and sell cards through eBay, TCGPlayer, and Instagram.


April 2020 - June 2022

SalesPlan started out as a consulting service. I offered sales coaching & fractional sales support for early-stage founders. During the first 2 years, I had the privilege of helping 100+ founders and SMBs grow their businesses.


May 2020

Guage was a weekend hackathon project I did with a friend. We built Gauge, a simple tool that helps you document, track, and make better decisions.


Feb 2017 - March 2018

Tagd was a pet care marketplace. We connected local pet owners with local pet care service providers. We lacked founder market fit (i.e weren't passionate about the idea) and shut it down.

When To Buy

Jan 2017 - Feb 2017

My first attempt at building a website. WhenToBuy was a simple website that let people know when the best time to buy any item. I built this site while I was searching for the best time to buy furniture and a few electronics. I figured that something like this already existed but I couldn't find a site that was simple and aggregated. So I built one.

The site contained articles on when to buy a particular item and links to discounts where appropriate. It was also equipped with a calendar with items sorted by the best month to buy for quick visibility.

Might bring this back one day!
