What I'm looking for

I seek senior engineering or architect roles where I can design scalable Java/React systems, drive cloud-native deployments, improve reliability, and mentor teams in a collaborative, delivery-focused environment.

I am a Senior Full Stack Engineer with over 20 years of experience building scalable, high-performance monolithic and microservice applications using Java and modern front-end technologies.

I have over seven years of front-end expertise delivering rich, interactive web applications with ReactJS and Redux, and extensive experience architecting RESTful APIs with Spring Boot using RestTemplate and WebClient.

My cloud and DevOps experience includes AWS (EC2, Lambda, S3, RDS, Amplify, CloudFormation, SQS), OpenShift, containerization with Docker, CI/CD with Jenkins and GitHub Actions, and monitoring with Grafana, Prometheus, and CloudWatch.

I have delivered production-critical systems for clients such as RBI, NCRTC, SHOP/Barnes & Noble and Morgan Stanley, improving throughput, fault tolerance, and reliability through techniques like Kafka-based fallbacks, query tuning, sharding, and robust retry/batch reprocessing mechanisms.
