   A digital health platform that connects patients with healthcare providers, nurse practitioners, and care teams through a centralized collaboration hub. Patients can search for doctors by specialty, language, location, and other filters, with the ability to designate or update their Primary Care Physician directly through the platform. The portal supports flexible appointment scheduling across office, phone, and video formats, enabling seamless care coordination between all stakeholders. Role-based access ensures that patients, providers, and nurse practitioners can interact and manage their workflows efficiently within a single unified environment. The platform is currently being enhanced with an Agentic AI Chat Agent — an intelligent assistant that consolidates patient and provider information into one place, reducing information silos and enabling faster, more informed decision-making across the care journey. Worked on various initiatives related to micro services or micro frontend, along with the Cloud and AI, using AWS and Azure.Technology Stack : Core Java, Spring AI, Langchain, Python, C++, Go, Generative AI, Agentic AI, Spring Boot, Spring AI, Langchain, LLM, JUNIT, FastAPI, PowerMock, Cucumber, Maven, Gradle, Mongo DB, FastAPI, JMS, JAAS, LDAP, SSO, GWT, Angular JS, Node JS, Apache Cordova, LangGraph, Twitter Bootstrap, Jenkins, Flyway, Oracle, Reactive Programming, React JS, Next JS, RAG, Vector DB, PL/SQL, T-SQL, gRPC, MongoDB, Redis, Cassandra DB, ChromaDB, Windsurf, Hazzelcast, Spring Flux, Apache Solr, Bamboo, Hibernate ORM, Cursor, OGM, Web Services (SOAP and REST), Docker, Ansible, Selenium, Git Hub Co-pilot,Cucumber, AWS, Docker, Kafka, Splunk, Kubernetes.
