Designed and developed microservices with Java & Spring Boot, deployed on AWS (Lambda, API Gateway, EC2, S3, DynamoDB) to build scalable cloud-native solutions. Implemented REST APIs and gRPC services integrated with PostgreSQL and Redis, reducing API latency by 30% and improving real-time data access. Built serverless workflows using AWS CDK, CloudFormation, and Terraform, applying Infrastructure-as-Code (IaC) best practices for consistent deployments. Developed full-stack applications with React.js, Node.js, TypeScript, and Express, delivering seamless end-to-end business solutions. Enhanced application performance & observability with AWS CloudWatch and X-Ray for monitoring, distributed tracing, and cost optimization. Integrated Kafka-based event-driven architecture, enabling high-throughput messaging and real-time data streaming across services. Implemented secure authentication & authorization with Spring Security and JWT, ensuring compliance with enterprise security standards.

Developed full-stack applications using Java, Spring Boot, Angular, React, Node.js, and TypeScript, delivering responsive and high-performing solutions. Designed and implemented REST APIs with Node.js, Express.js, and Spring Boot, integrated with AWS DynamoDB & PostgreSQL for scalable data management. Built serverless AWS applications leveraging Lambda, API Gateway, S3, and CloudFormation, reducing infrastructure costs and improving deployment speed. Migrated legacy systems to AWS RDS (Aurora), optimizing database performance and availability for enterprise workloads. Implemented OAuth2-based authentication and JWT security with Spring Security, enabling secure third-party integrations. Integrated Kafka & SNS/SQS messaging for event-driven architecture, ensuring real-time and fault-tolerant communication between services.
