Hi, I'm Umanandan Sagar Chukka, a software engineer with 4 years of experience designing and deploying scalable microservices and APIs using Java (8/11), Spring Boot, and Spring Security. I have extensive experience with AWS cloud services (EKS, S3, DynamoDB, Lambda) and infrastructure automation with Terraform and Jenkins, delivering secure, high-availability applications. I've optimized performance through Redis caching and SQL tuning, reducing API latency by over 35%. I built Kafka-based event-driven architectures and integrated AI/ML models using AWS SageMaker, TensorFlow, and retrieval-augmented generation with Pinecone and FAISS. I follow TDD/BDD in Agile environments, achieving 90%+ code coverage, and enjoy collaborating across teams to drive reliable software delivery.…Hi, I'm Umanandan Sagar Chukka, a software engineer with 4 years of experience designing and deploying scalable microservices and APIs using Java (8/11), Spring Boot, and Spring Security.
