Software Developer in Peoria, AZ, United States

I was hired as a senior full-stack developer (Node.js and Angular 8). After delivering an outstanding product, the contract was extended and moved to another team where I engaged the role of the product architect and later team lead. Together with my team, we created a product from the ground up for helping helpdesk workers to manage external customers. Used NestJS with Angular to create the back end and front end. Managed local and offshore developers.

I was a senior full-stack developer (NestJS, Angular 8) and developed the back-end and front-end application that would analyze the open-source projects for known vulnerabilities and report the risk score of the project. The goal of this project was to assess the security risk of using open-source projects inside the United Healthcare company and its subsidiaries. The project was delivered in time.

I joined this company when they had a proof-of-concept SPA written with the first version of React, after Facebook had just released it. My duty was to fix bugs and add new features. As the product evolved, I realized that the current architecture is no longer extendable and proposed that we rewrite it using the modern React patterns, such as Redux and Router. I architected the new product, making it more robust and easily extendable. The addition of Redux allowed us to have all the data in one place and add unit tests. After this success, I was asked to develop two more applications for them, a kitchen visualizer with real-time updates based on user selection of the granite, and a back-end dashboard for the fabricators. Both projects were delivered in time.
