BI Data Engineer

May 2019 to Aug 2020

Letgo provides a marketplace that allows users to buy from, sell to and chat with others locally. The products launched in 2015. By September 2015, its app had two million downloads and half a million product listings. In 2017 it was the second fastest growing app in the U.S.

My main objective consisted on providing stakeholders inside and outside the company with relevant data in a timely manner, managing over a hundred pipelines in Airflow that deliver all the data necessary —pulling from tens of databases and external sources, and hundreds of domain events— to our internal customers —data analysts, data scientists, trust and safety and customer care agents, finance and high management—.

Kott Müller

Founder

Nov 2015 to Oct 2016

My partners and I created a shoes brand that produced locally. We managed everthing: from building the site from the ground up to logistics, finance and marketing. While the company didn't reach the goals we initially planned, here's what I learned:

You need to sorround yourself with people that have not only complementary skillsets but also personalities. Partnering with someone is like marrying. Choosing the right people is key.

You can't engage into building complex structures in an early stage startup Thats how I know I'm not fit for them anymore. I need the basics covered so I can specialize.

Obstacles that you don't account for are going to come up all the time. You need a lot of grit to deal them.
