In 1997, Bob Lee started working at Redrock Communications. He remained there for a year before he started working as a web developer at D’Arcy, as well as the Southeast Missouri State University, where he obtained his degree.
Next, between June of 2000 and August of 2001, he worked at a company called Capgemini. He left this company to join Ajilon Consulting, another company that employed him for a year.
On August 7, 2001, Bob Lee developed and released a free program that defended the Microsoft IIS servers from a rapidly spreading computer worm called Code Red.
Between 2002 and 2003, he freelanced as a consultant for FiveSight Technologies and Plateau.
In 2003, he started working as a technical architect at AT&T, where he developed a framework similar to Java’s Spring Framework, one that was featured in Oracle Magazine. The aspect-oriented programming network was named Dynaop.
Between 2004 and 2010, Bob Lee worked as a staff software engineer at Google. He was part of a team that was developing the Android operating system.
While at Google, Lee developed Guice, a dependency injection framework that he worked on with Kevin Bourrillion. The framework was completed in 2006 with the goal to modularize AdWords.
Two years later, the two partners won the Jolt Award for their development of Guice.
In 2007, Lee transferred to a different team at Google. He started working with the core libraries team and soon after, was assigned to be the team’s leader.
He was part of the group for Java proposals and also worked on an Android process virtual machine called Dalvik.
Square and Cash App
Before his famous work at Cash App, Lee was involved in several other successful ventures. For instance, in 2007, he founded The Echo Nest, a music streaming service that offered music recommendations to companies like Spotify. Spotify bought his business in 2014, but the amount of the purchase is unknown.
In 2010, Bob Lee decided to leave Google after his successful tenure at the company. He did this to join an ecommerce company called Square, where he worked as the chief technology officer.
In 2022, Square reported a revenue of $13.18 billion. While his exact salary at the company is unknown, he had stocks and earned a lot of his net worth from this business.

In the beginning, Cash App was called Square Cash. Lee developed it as a smartphone-based app for payments and money transfers, as well as investments in cryptocurrencies and stocks. The app went live in 2013.
The cash app founder envisioned his product as a comprehensive platform that offered a wide range of services. That being said, he transformed it over the years to include a variety of features.
Today, unlike banks, Cash App allows users to easily transfer funds to others, make investments online, pay their bills, and much more. Before Bob Lee’s death, the app had over 50 million verified monthly users.
