My work at Emizor system was mainly maintenance. Solving bugs and sometimes modifying some features.Vendis POS was a web-oriented application at the beginning, but my job was to create an API that communicates with the Android application.Finally, FEL (Facturación Electronica en Linea) was a REST API that simplifies the current official invoicing service (SOAP) in Bolivia. My work in this project was to design the solution and abstract the current Bolivian invoicing system. That is because the actual system is a little complex.My daily tasks include:- Web applications and REST APIs development.- Improve system performance by refactoring code and optimizing database queries.- Contribution in the systems infrastructure design using Amazon Web Services technologies.- Improvement in the development environment "dockerizing" the three company's systems.- Development of asynchronous processes using ActiveMQ to guarantee invoice processing.- Subscription system implementation using stripe.- Analysis of the user's feedback to add or modify the application features.- Database design.- Contribution to separate different system processes to microservices.- Adaptation of a soap service to REST service.
