Agile Thought•  May 2021 - Present

IT Senior Analyst in the FIRST group, a Santander technology group, such as a developer of new projects and component structuring using Java as the main technology. Currently focused on the development of Microservices using Java and Spring Boot technologies. Also, working in the digital platform of the Commercial Portal for PF and PJ as a requirements analysis, development and implementation of high criticality/availability projects. The documentation is aimed at Service Architects, Developers, Directors and Project Leaders. As well, I joined at the Open Finance project, migration strategies of existing projects for more scalable solutions (migration of the ZUP platform for Apigee), asynchronous and synchronous communication, monitoring, traceability and metric techniques with Jaeger, Kibana, Grafana and Dynatrace. All compatible with the cloud infrastructure of Azure Kubernetes Service and OpenShift Container Platform. Besides, working in the creation of the Open Insurance system, in the definition and implementation of new microservices. Using Confluence for functional and technical documentation aligned to the solution proposal, serving as Input for developers facilitating the use and understanding of the software, mainly for its evolution/scalability. Also developer of software components that directly impact the lives of thousands of clients, thus always seeking to guarantee quality and fault in all projects developed. As a member of the IT area, I used to share knowledge with other developers within agile teams, such as technologies used, design patterns, and software architecture. Commonly used technology: • Java 6, 8 e 11 • Stack Spring, Boot, Cloud, Data, Security, AMQP and GraphQL • Docker • Kubernetes • OpenShift • Redis • Jenkins • RabbitMQ e IBM MQ • ZUP for API gateway • Apigee • Git and GitLab • Sonar • Fortify • Atlassian Jira • Confluence • Kibana • Grafana • Dynatrace • Jaeger • AKS Aptitudes: Software Engineering · Java

IBM•  June 2016 - December 2019

Developing cloud, Mobile, Web and Microservices solutions for Business problems solved through technology approach, defining architecture and high availability/resilience strategies. As the first point of contact for customers, our desitions asa team are crucial for company KPI's. Managing agile projects using the SCRUM methodology. Collaboration and support with multiple platform based projects such Java, Python, Javascript, PWA, infrastructure improvements and implementation of distributed tracing for microservices. In the technical aspect, my principal functions were: • Develop polyglot microservices applications (Java, Python, Node, Golang), with fault tolerance features, asynchronous process and queue orchestration to ensure data/process integrity. • Introduce Docker as main tool for setup a development/QA/prod environment through automated deployment pipelines. • Implementation of Continuous Integration / Delivery cycles through automated pipelines (Jenkins based), deploying on cloud providers such IBM Cloud, CloudFoundry and local servers (Automated remote provisioning). • Lead the migration from old stack services to modern frameworks/tools. • Integration with 3rd party providers. (PayPal, Culqui, PayU) • Platform maintenance, bug resolving and code optimizations. • Development and maintenance of web and mobile applications for local clients. • Facilitate meetings, lead / support team focusing on user requirements. • Constant participation and training on software development through agile practices. • Use Git, Jenkins and Docker to satisfy the needs demanded in an evolutionary architecture, making a cycle of continuous integration / delivery. • Creation of push notification services to improve vendor-provider communication. • Lead migration from SenchaJS to open source frameworks, such EmberJS, Angular. • Develop new applications using React, InfernoJS (Proof of concept) and Aurelia. • Active participation in UX design and product discovery sessions.
