Professional Summary:

Over 6 years delivering endtoend Java/J2EE solutions—from requirements gathering and design through development, testing, and production rollout—across largescale web and client/server distributed systems.

Built MVCdriven web applications with Spring MVC, then refactored them into Spring Boot microservices under a SOA architecture, leveraging Java 8 Streams, lambdas, Predicates, functional interfaces, method references, Filters, and enhanced Collections.

Crafted dynamic, responsive UIs using HTML5, CSS3, JavaScript, jQuery, Bootstrap, React, and Angular, wiring React components to RESTful and Graph QL endpoints, and managing application state at scale with Redux and the Context API.

Architected realtime, eventdriven data flows using Apache Kafka (producers/consumers), Storm topologies, and Kafka Streams (DSL & KSQL), ensuring reliable highthroughput messaging.

Containerized services with Docker and orchestrated deployments on Azure via Harness, plus scripted infrastructure as code with Terraform and Ansible, and automated CI/CD pipelines using Jenkins, Cucumber,Quay, and Artifactory.

Integrated Azure Monitor and Application Insights for end-to-end observability of microservices, enabling proactive performance tuning, real-time alerting, and diagnostics in production environments.

Provisioned and managed Azure resources including Key Vault, Storage Accounts, and Azure Logic Apps, integrating them with Java microservices for secure secrets handling and workflow automation.

Designed and executed data migrations from SQL to multiple NoSQL stores—MongoDB, Cassandra, CouchDB—and used Hibernate for ORM (connection pooling, mappings, transaction management, HQL) with comprehensive JUnit test coverage under TDD and Scrum (and Waterfall) methodologies.

Provisioned and managed cloud resources with AWS CloudFormation, Chef, and Maven, and deployed J2EE applications to Tomcat, WebSphere, WebLogic, and JBoss environments.

Champion AgileSafe practices in a HIPAAregulated healthcare domain, enforcing security standards (OAuth 2.0, JWT, RBAC) and collaborating via GitHub versioning to ensure traceable, highquality releases.
