Responsibilities & achievements

Maintenance of applications on (Java, Node JS,Meteor, Mongo) Stack for the Science industry. Application maintenance. React a11y issues fixes were applied to some of the client applications. Some microservices were improved using Java/Kotlin and Spring Framework. Some Frontend applications that were written on Angular requires some changes that i made.

FullStack Development (Java/Spring) (AngularJS) (ReactNativeapplications) for the health industry. Applications maintenance. This client has a set of microservices that allow frontend and other clients consume the API, my job was directly involved with the migration and maintenance of those endpoints. In some cases I just made some modifications on the parameters that were used on the endpoints, in other cases I had to implement new ways to do some calculations that were required given the application business logic. The documentation of those endpoints was migrated from swagger 2 to OAS 3 in order to get a clear way to present the endpoints to the consumers.

Full-Stack development. This client has an application as a service that is closely related to Health Care, so in this job i perform solutions on the backend and frontend side: Chat: using twilio integration to solve the chat communication part, on the backend side the integration was made with Java, on the frontend side the chat was implemented on React JS for clients and Angular Js for SaaS clients (Hospitals and Independent Doctors) VideoTelemedicine: At the beginning this solution was implemented using JitsiMeet, with this implementation you can create your own VideoChat Rooms with your own servers, at that point we decided to use that implementation given all the flexibility provided by JitsiMeet, after some time we require to create recordings of this Telemedicine video calls and we decided to move from Jitsi to Twilio Video, the main issue with Jitsi for this purpose is creating multiple instances dedicated to record every call, so imagine two hundred calls at the same time using 2 hundred servers to record those calls… so we decided to move to a more administered service like Twilio video.

• Full-Stack development. This client wants an application that can track the position of students (childrens) by their parents involving a mobile application that can show that tracking… so for this solution i use a backend side on Java/Spring and an application on IONIC using angularjs as main language. The backend side have some endpoints exposed to control the configuration made by every parent for the number of childrens that they want to track, the schools that have those childrens registered can configure some parameters too. On the frontend side all those configurations mentioned above were available to change. The application can be used by the parents of the childs and by the driver that have a set of childs to drop on every house, so he can inform things like traffic, or any other notification that can be relevant to the parent/school. This application was created from scratch with the tech stack mentioned below.

Back-End development. A set of endpoints were exposed to an application that allows the users to get an appointment in any place that uses the application (Hospitals, Banks… etc) the solution was implemented using Java/Sprin JavaEE Developer,usedframeworksEJB,Primefaces,Hibernate,JPA.

This time i worked on the same applications that were described above on the Coomeva company but at this time i worked as a outsourcing developer. This company provides a service to the clients, where the client can ask for an ambulance service… they have multiple applications that are involved in this process.. i worked on some of them: The first of those applications was the applications on charge to control every ambulance that is available on the company, they handle multiple status, and a lot of information related to the ambulance and its occupants.. (driver, doctor and nurse), this system have control over the tracking of the ambulance, so you can query at any moment the route that the ambulance follows…. That part of the application was handled by a communication between a system inside of the ambulance provided by a third party and an integration with put systems on Java/Spring the communication was achieved using some endpoints or messaging queues. Another application has information about the occupants (Drivers, Doctors and Nurses) and information about all the things inside of the ambulance like equipment needed for attending an emergency… all this information was collected on an Oracle Database that was connected to our Java/Spring application. The last application involved in this process was an application made on JSF (Primefaces) that was used by the people inside of the ambulance, they can perform some actions on it like create a form for the client that is being attended at the moment of the service… ask for information to the hospital if it is needed, share the location of the ambulance to the family of the person that is being attended… all these services where exposed using some services published using Java/Spring monolith that after some time was migrated to microservices given the number of requests that the monolith was handling at some point.
