- Developing Scalable Microservices: Designed and implemented Java microservices to support logistics and reporting solutions for B2B partners. These services enable partners to better manage and understand their sales flow, improving overall logistics.- Building and Optimizing Data Pipelines: Built and maintained complex data pipelines using Directed Acyclic Graphs (DAGs) to streamline the generation of reports, ensuring the seamless flow of data across various systems.- Performance and Load Testing: Led projects focused on performance optimization, including load testing our services and refining their data structures to support a significant increase in data volume.- Ensuring SLA Compliance: Worked closely with stakeholders to ensure that services met the agreed Service Level Agreements (SLAs), even with substantial increases in data and traffic.

- Experience in a complex and highly demanding and distributed environment, participating in all phases of the project life cycle- Designed a National Judiciary Platform of services using microservices, APIs, and message-based communication with technologies such as RabbitMQ, SpringBoot, and Netflix services- Established guidelines and protocols for new services, APIs, and messages and reviewed code to ensure quality, while streamlining the development process and incorporating Domain-Driven Design (DDD)- Collaborated closely with product owners and stakeholders to reconcile conflicting needs, ensuring the technical team understood requirements and delivered user-focused solutions. Resolved over 3,000 backlogged issues and maintained project priorities and deadlines. Also served as a solution architect and evolved legacy systems.- Implemented projects to move from a monolithic solution with session based services using Jboss Seam to a session-less microservice environment with an event-based architecture, utilizing RabbitMQ- Developed CI/CD pipelines using Gitlab and GitHub Actions to deploy applications on a AWS-based Kubernetes solution- Participated on a project to plan and test moving from a solution based on RabbitMQ to Apache Kafka- Participated and helped design ELK solutions to centralize the logs of various microservices for some tribunals- Developed bots that integrated with the message broker to automate tasks inside Slack, GitLab, Jira and Telegram, improving overall communication and helping the developers and the product team to adhere to the patterns and workflow of the projects.- Utilized technologies such as Java, SpringBoot, Mysql, Angular, Bash, Gitlab, AWS, Kubernetes, Docker, ELK, Python, MongoDB, Postgres, Apache Kafka, Webhooks, Keycloak/SSO

- Worked for educational client merging and evolving technologies from a newly acquired partner- Maintenance and evolution of Java (version 11), Kotlin, Angular and Python services- Developed features that reduced incoming support tickets by 15-20%- Experience as reviewer and mentor for new developers, sharing knowledge and best practices to enhance their technical skills and contribute to team success- Assisted other developers with the use of Java and the tech stack- The BairesDev team had 25 people, plus more dozen of client’s developer, product and engineering team- Improvements and optimizations on the DevOps pipeline- Defined patterns, created reference implementation, and implemented autonomous tests using Cypress- Environment: Java, SpringBoot, Kotlin, Angular, GraphQL, RestAPI, Github Actions, MongoDB, MySQL, Keycloak/SSO, Bash, Docker

- Maintenance and evolution of Java Legacy Systems (version 7)- Identification and implementation of optimization opportunities in systems- Development of a DevOps pipeline using Azure to automate build and deployment of new versions, leading to a uniformization of all clients- Refactored all code and moved from Glassfish Server to Tomcat Server and then to a SpringBoot server, facilitating maintenance and evolution of code- Implementation of an APM integration using Grafana, Prometheus, Glowroot, and Traefik to centralize all reports and management of clients, making it easier to find bugs and report malfunctions- Technologies used: Java, Firebird, Mysql, SpringBoot, Traefik, Glowroot, Prometheus, Grafana, Azure DevOps.

- Maintenance and evolution of the Java Systems that streamlined the lending process and enabled the bank to provide financial support to a greater number of companies with increased speed and reduced bureaucracy. This allowed for more efficient and agile loan dispensation through the web.- Design and implementation of a comprehensive system for BDMG to manage and oversee investment projects from companies intending to invest in areas within its jurisdiction in the coming years, including the companies' requirements for public sector counterparts.- Environment Java, JSP, Tomcat, Mysql, SQLServer, Bash, PHP, SVN
