Development of applications (Web Services and REST APIs) using Java microservices (8, 11, 17) and Spring Boot, serving foreign trade systems and integration with other systems. Use of Hexagonal architecture and building BFF applications with Apache Camel. Migration of legacy Java 7/8 services (WebSphere 8.5) to comply with vulnerability standards. Use of JUnit, Mockito, JMock, and WireMock for unit testing. Database entity modeling with IBM InfoSphere Data Architect and Oracle (11g/19), creation of packages, procedures, and scripts (PL/SQL), and deployment with Liquibase. Development of large-scale applications using Spring Batch and scheduling in Control-M, monitoring and creation of workflows with CLI DataOps for exchange and derivatives data. Adherence to code quality tools (SonarQube, Fortify). Development of Micro Front-Ends (MFE) with Angular 17, TypeScript, and Jasmine. Building microservices in Node.js for exchange orchestration. Use of market best practices (code-review, design patterns, clean code, DDD, TDD), Gitflow, Gitlabflow, automated testing, modularization, and code optimization. Monitoring of deployment packages using DevOps pipelines (Jenkins-CloudBees), Pert, Gmud, and Releases. Use of messaging systems like IBM MQ, RabbitMQ, and Apache Kafka for resilience in asynchronous processing. Maintenance of legacy .NET C# systems and building ETLs (file exchange).
