Dynamic Software Engineer and Full Stack Cloud Developer with hands-on experience designing, building, and deploying scalable cloud-native applications on AWS. Skilled in crafting efficient React.js frontends and Node.js/Python backends, I deliver seamless user experiences backed by high-performing, secure, and automated infrastructure.I specialize in leveraging AWS services such as EC2, Lambda, RDS, S3, and API Gateway to architect resilient systems while integrating GraphQL APIs and microservices with enterprise middleware like WebSphere and Tomcat for smooth interoperability.Proficient in Terraform and CloudFormation for infrastructure automation, I’ve streamlined provisioning workflows and reduced setup time significantly. My experience also extends to developing machine learning models in SageMaker to enhance predictive accuracy, and integrating AWS AI services (Rekognition, Comprehend, Personalize) for intelligent and personalized user applications.With strong expertise in CI/CD pipelines using CodePipeline, Jenkins, and GitHub Actions, I ensure faster, reliable releases, and maintain compliance through robust IAM, VPC, and encryption configurations. Additionally, I’ve implemented real-time observability using CloudWatch, ELK, and Datadog to improve system reliability and incident response.Collaborating with distributed teams across the US and India, I thrive in agile environments that demand innovation, adaptability, and end-to-end ownership — from code to cloud.
