GroceryPress is a personalized digital promotions and loyalty applications suite for natural and specialty retailers. I worked as full-stack engineer in various parts of the project, first building a front-end application called Consumer using AngularJS. I structured the whole architecture, CI, and continuous deployment. Built a console application that runs on client machines to extract data from Sybase DBs as well as manipulate and communicate to GroceryPress FTP server using Java with Gradle builds. I worked on the core application on ingestion module to enable Spring Batch ingestion of client data into multi-retailer DB.

IEPD is an inter-enterprise data orchestrator that treats and routes calls from failing hardware devices, and takes immediate actions to solve the problems. Those calls can come from web services calls or emails. I worked as a Java developer writing components for that application. After 2013, IBM started using a new methodology for development called Liquid, where the development is packed in small pieces and externalized. I worked on implementing this new methodology in our project, preparing environments in cloud servers, planning the specifications for the developers, overseeing the process and reviewing the code.

Flavour is an application developed on Back4App using a Parse.com back-end. I worked as the lead developer of the project, writing Cloud code functions and Jobs in JavaScript. Some functions were integrated with external services like Foursquare, Yelp and Algolia. Developed tests with Node.js testing suite with Mocha, Sinon and Chai.

Autocrop is an internal tool that I built for Tasting Table that enables the user to make multiple crops of a picture in a single-page app. It uses AngularJS 1.x for UI, Cropper.js, and Imgix API for manipulating pictures. I also created a Java back-end for managing the requests and calling external APIs.

Work Force Analytics is an application that uses employee data for building analytics visualizations like charts and widgets. I've worked as the lead architect and developer, having set up the continuous integration and deployment pipelines. The application back-end was built using Spring Boot and derived technologies using Oracle and MongoDB as data sources. The front-end used Angular 2+. As the project was on very tight schedule, there were timing challenges to be fought as well.

ADP's HR portal is one of the most successful and used in the world and was migrating their portal to a PaaS platform. I worked as a Java developer on the security components conversion.

I developed a Salesforce application from scratch to a former Java platform for handhelds called TotalCross. Since it used Java 1.3, I had to implement some code needed from higher versions of Java using basic calls. I developed an ORM framework with Hibernate and JPA functions. This application communicated with a back-end to synchronize sales data.
