I worked as a back-end developer migrating the existing Node.js and TypeScript back-end microservices to a monolith service using domain-driven design (DDD) principles. My work included developing new features, fixing bugs on the React/TypeScript front-end application, and performing deploys on the production environment and production support of the product.

As a full-stack developer, I built a website using React, Stripe, and Java Spring Boot. This website allowed resellers to apply for a debit card, send and activate the card, as well as display the card balance and expenses. Additionally, I integrated a recently acquired application (service locator), which consisted of two web apps built on Angular and React, along with two REST APIs developed on Next.js and Go, into the AppDirect platform using Docker, Kubernetes, and AWS. My work also involved migrating a database with over nine million geocode addresses from PostgreSQL to MySQL and adapting the addresses to a new model using the Google Geocode API.

I worked as a full-stack developer migrating existing components from JSP to a new React-based environment, developing new features on Java Spring REST services and SQL, and maintaining existing features on the website with Java Server Pages.

I developed the mobile app from scratch. I designed the architecture and developed the REST API that the app consumes, as well as an internal web application for managing the information displayed by the app.

I developed the single sign-on login on the Exhale Angular 7 application and Java Spring back-end to communicate with the Hyatt SAML server. I also worked on several new features and bug fixes for the front-end and back-end systems.

I was part of the team that developed and deployed the REST API consumed by this app. I worked for four months at the client's offices in Florida until the first version was released and then worked remotely for subsequent releases. The app allows a guest to register and use a chat service to communicate with other guests, view a map of the different decks, and check activities, restaurant menus, and the entire cruise schedule.

I worked on the API that provides all the info related to entertainment, attractions, restaurants, menus, resorts, room info, etc. I worked for two months at the client's offices in Seattle, implementing the API and providing help to UI teams for consuming the complete set of services.

I worked for more than a year on implementing the REST services for this website. I interacted with teams in different countries and time zones, executing performance tests, and providing production support for live site issues.
