Design & Build Microservices: Develop clean, testable, and maintainable services in Java (preferably Java 11+/17) using Spring Boot or similar frameworks.
Workflow Orchestration: Model, implement, and optimize business processes using Camunda (BPMN/DMN); create/maintain process definitions, external task workers, and decision tables.
Cloud Engineering on AWS: Architect and deploy services using AWS (e.g., ECS/EKS/Lambda, API Gateway, SQS/SNS, RDS/DynamoDB, CloudWatch, IAM, Secrets Manager), ensuring scalability, observability, and cost efficiency.
APIs & Integrations: Build robust RESTful APIs, event-driven components (e.g., Kafka/Kinesis), and integrate with third-party/internal systems securely and reliably.
Quality & Reliability: Write comprehensive unit/integration tests; enforce code quality and coverage; participate in code reviews, refactoring, and performance tuning.
