Lead Full Stack Java Developer

Responsibilities:

• Managed a team of developers, mentored new ones joining the team, responsible for task allocation, pair programming and ensuring best code quality and practices.
• Redesigned existing PHP monolithic application in a java based microservice application to remove duplicate work and separate concerns. The core was made using Spring 3, Hibernate, My SQL and C# for desktop clients.
• Redesigned and developed existing PHP application to consume Rest Web services instead of using the existing code.
• Developed Rest Web Services with Java 6 using JAX-RS to support customers info, invoices info, control access info and maintenance support info.
• Redesigned customer control access application to reduce the in and out time. The old application used to have a connection to the database and get the customer’s photo and fingerprints from a remote server, the solution was developing a new C# app that consumed a Rest Web Service developed in JAVA 6 using JAX-RS and Hibernate and setup a local server to store all photos and fingerprints.
• Rearchitected the old application to design a multi club solution to allow customers to get access to any facility using a single registry.
• Developed features to consume Rest Web Services using JAVA JAX-RS from the related bank service to provide automatic monthly charges to customers.
• Developed features to create a Rest Web Service to support assets management like towels and lockers. The Rest Web Service was made in Java using JAX-RS and C# as desktop app.
• Developed features to create a mailing service to send promotions, invoices and notifications to customers using JAVA 6, Spring 3 and hibernate.
• Added new features using less code. Due the monolithic application was turned in a microservice app, it was very easy reconfigure the existing apps to add new functionality such a new training program that used separated facilities and separated customer control access.
