  • Strong proficiency in Java 21, including records, sealed classes, pattern matching, and virtual threads.
  • Proven experience designing and developing microservices architectures.
  • Extensive experience with Spring Boot and the Spring ecosystem, including Spring MVC, Data, Security, and Cloud.
  • Hands-on experience with Spring Batch for large-scale data processing.
  • Strong Hibernate/JPA and relational database experience, preferably PostgreSQL.
  • Experience building and consuming RESTful APIs, including API versioning and contract-first design.
  • Experience with inter-service communication using REST, messaging queues, and/or event-driven patterns.
  • Experience deploying and operating microservices on AWS, including services such as EC2, ECS/EKS, RDS, S3, SQS, and Lambda.
  • Experience with CI/CD tools such as Jenkins or GitHub Actions.
  • Strong knowledge of design patterns, SOLID principles, clean code, Git, and collaborative development.
  • Understanding of distributed systems concepts including fault tolerance, circuit breakers, retries, and observability.
Desirable Qualifications
  • Experience working on government, state, federal, or other public-sector IT projects.
  • Experience with microservices patterns such as Saga, CQRS, event sourcing, and API composition.
  • Experience with Docker, Kubernetes/ECS, and service mesh technologies.
  • Knowledge of SQS, SNS, Kafka, API Gateway, or Spring Cloud Gateway.
  • Experience with centralized logging and distributed tracing tools such as CloudWatch, Splunk, Datadog, Zipkin, or OpenTelemetry.
