7 years of experience working as a Full Stack Developer across frontend, backend, cloud, and DevOps layers for enterprise-scale applications. Designed and developed responsive, high-performance web applications using React and Angular (up to v16), including implementation of Angular Module Federation for dynamic loading of components and micro-frontend-style modularization. Built and maintained scalable backend services using Node.js, Express, GraphQL, and REST APIs, focusing on performance, modularity, and reusability. Improved backend response times and overall system performance by refactoring legacy codebases and introducing a Redis-based caching mechanism, significantly reducing repetitive database calls and improving API efficiency. Developed Python-based backend components for text processing and intent identification using the Rasa framework, and implemented Trie-based algorithms to deliver efficient, low-latency search suggestions. Integrated data visualization libraries such as Vis.js and Cytoscape for complex graph-based UI representations. Implemented authentication and authorization using Keycloak and Azure AD, supporting enterprise SSO requirements. Containerized applications using Docker and Docker Compose and supported deployments on Kubernetes environments. Automated build and deployment workflows using shell scripting, reducing manual deployment effort. Worked with AWS services (Lambda, EC2, API Gateway), including implementation of AWS WebSocket API Gateway to enable real-time push messaging for a B2B e-commerce platform. Actively participated in Agile/Scrum ceremonies, collaborated with cross-functional teams, and contributed to design discussions and code reviews.
