I worked as a Software Architect on a project that uses Java and Spring Boot as the main development frameworks, implementing a microservices architecture hosted on Microsoft Azure Cloud. In this role, I extensively use Azure Kubernetes Service (AKS) for container orchestration, ensuring scalability and resilience across applications.

The project also integrates services such as Azure Event Hub for real-time event processing, Key Vault for secure secrets and key management, and Cosmos DB and PostgreSQL as database solutions to meet different data persistence needs.

For software lifecycle automation and management, I use Azure DevOps, which enables streamlined CI/CD pipelines and source code management. Application monitoring and observability are ensured through Azure Monitor, guaranteeing performance and service availability in production.

Worked as a Senior Java Developer, focusing on backend engineering using Java and Spring Boot. Designed and implemented microservices and RESTful APIs with an emphasis on performance, scalability, and maintainability.

Developed and maintained data processing pipelines integrated with Apache Kafka (using Avro schemas), ensuring efficient and reliable event-driven communication.

Worked with MySQL and MongoDB, handling database schema design, query optimization, indexing strategies, and transactional operations to support high-volume, mission-critical workloads.

Worked as Senior Systems Developer responsible for development, maintenance, and evolution of academic and administrative enterprise systems using Java. Full participation in the development lifecycle, building web applications with Spring Boot, JPA, Hibernate, and REST APIs. Contributed to modernization and refactoring of legacy systems.
