Startups Refund for Mainstreet
A React-based app to help new startups get the best option while dealing with government funds. I was the front-end developer and liaised with the back-end developer to integrate all the self-signed up flow and also the qualification process. Also created the front-end tests, both unit, and integration tests. Created, refactored, improved, and suggested many of the components used on the MVP project. Sometimes also helped on the back end adjusting API calls to fit the new client's requirements.

An Angular and Java-based app for managing shipments available and apply the logistics. I was the full-stack developer and created, from scratch, the front and back end. I've integrated it with a third-party API to deactivate an old system they were using.

The back end was built using Spring Framework and had to persist some information in a PostgreSQL database. The front end with Angular (version 10), TypeScript, and Angular Material UI.
