Customer: Santander Mx-I developed a microservice responsible for converting data saved in a non-relational database (from JSON) to a relational database. This microservice is executed every day at midnight using Kubernetes Cron Jobs. It uses the MongoDB BI Connector to create CSV files, which are then uploaded to an AWS S3 bucket using multipart upload. These files are utilized by the Data Lake team.-I created a microservice responsible for generating accounting reports by extracting data from a non-relational database (MongoDB) and creating a tar.gz file using Java libraries. This microservice is executed every day at a specific time and it queries another microservice using synchronous communication (REST).-I maintained a microservice responsible for communicating with a customer application using IBM MQ and receiving Kafka events, which trigger the process of retrieving data from another microservice via REST communication. The primary workflow follows the happy path; if there is an issue with customer communication, the microservice employs the Circuit Breaker pattern to save data in a MongoDB while continually attempting to communicate with the customer application. Once communication is restored, the microservice notifies another microservice using synchronous communication to recover all data from the database and create a contingency file, which is then sent to the customer department via an AWS S3 bucket.-Fluent communication with Spain Team to solve work situations.Design patterns:DAO, DTO, MVC, Circuit Breaker, Event Driving.

Customer: Michelin-I was responsible for developing microservices to monitor environmental values such as temperature, pressure, and other relevant metrics within a Michelin Factory building. These microservices continuously gathered data from various sensors installed throughout the facility, ensuring real-time monitoring and data accuracy. Additionally, the microservices retrieved data from the database to expose endpoints for consumption. The data was stored by other microservices using REST APIs.-Creation of REST API using micro services (MS) in Java.-I performed create, read, update, and delete (CRUD) operations on records stored in tables within an Oracle Database. This involved writing complex SQL queries and ensuring data integrity and consistency across the database.-Use of Spring Boot for a fast deploy usingJava.-I employed Git as the version control system, ensuring proper tracking of changes, collaboration among team members, and maintaining the integrity of the codebase. This included creating branches for new features, managing pull requests, and resolving merge conflicts.-Creation of Docker containers using docker compose.-Design patterns, DAO, DTO, Config Server, MVC.
