Architected and optimized scalable Java/Spring Boot microservices integrated with Kafka, improving responsiveness. Built responsive React/Node.js front-end features and reusable UI components. Implemented concurrent processing utilities using Java concurrency APIs and streams. Developed RESTful APIs and full-stack solutions (REST/GraphQL) backed by PostgreSQL. Built CI/CD pipelines with Jenkins and achieved high test coverage using JUnit/Mockito. Containerized services using Docker and deployed on AWS (EC2/ECS/EKS) with Kubernetes for scaling and availability. Implemented asynchronous messaging with ActiveMQ and event-driven serverless workloads using AWS Lambda and Step Functions.

Designed and developed scalable, event-driven microservices using Java and Spring Boot, integrating Apache Kafka for real-time processing across multiple downstream consumers. Built responsive front-end applications with React, Redux, Next.js, Node.js, and TypeScript, contributing reusable components to a shared UI library. Implemented multi-threaded Java utilities using J2SE concurrency APIs (ExecutorService, Future, CompletableFuture) to improve throughput under high load. Delivered end-to-end full-stack features including GraphQL and REST API design backed by PostgreSQL, plus corresponding front-end implementation and releases. Supported Jenkins CI/CD pipeline improvements, containerized services with Docker, and deployed Spring Boot microservices on AWS EC2. Participated in code reviews and collaborated with product, architects, and QA to align service boundaries and API contracts. Explored Generative AI/LLM-assisted tooling for code generation and testing workflows.

Delivered full-stack development for Alexa Video onboarding using Java/Spring and cloud-native microservices on AWS. Refactored legacy backend APIs using TDD to improve throughput for large-scale integrations. Implemented RESTful services and J2EE components (Servlets/JSP/EJB) for high availability. Built onboarding experiences across Echo Show devices. Implemented streaming workflows with AWS Lambda integrating SQS/SNS/Firehose/S3 and orchestrated pipelines using Step Functions. Created CI/CD using AWS CodeCommit/CodeBuild/CodeDeploy, deployed containerized services on ECS/EKS, and used CloudWatch for monitoring. Achieved 90% unit test coverage with JUnit/Mockito and reduced regression time.
