Sharan Varghese

Innovative Software Engineer with extensive experience in full-stack application development and deployment. Skilled in leveraging MERN and Django frameworks along with AWS cloud infrastructure to enhance operational efficiency. Expertise in REST API engineering, real-time communication with Socket.io, and secure user authentication.

• Cloud-based Hospital Assistant (Deployed)

Demonstrated strong expertise in cloud-native architecture and AI orchestration by building a production-ready healthcare assistant on AWS. Leveraging AWS Bedrock and Kendra, I implemented semantic search capabilities that cut lookup times in half and improved response relevance by 30%. I engineered robust data infrastructure using AWS Glue pipelines to handle diverse datasets—boosting query performance by 40%—and optimized user session storage using DynamoDB to maintain sub-100ms latency while scaling concurrency threefold. The final product seamlessly unified a Node.js and Spezi frontend via secure REST APIs, driving a 40% reduction in manual clinical documentation.

• Real Time Chat Application

Showcased full-stack development capability and security-first engineering through a deployed real-time communication platform built on the MERN stack. I designed and scaled secure REST APIs using Node.js and integrated Socket.io to establish persistent, low-latency data channels for messaging and presence tracking. To ensure user safety, I built a hybrid AI moderation engine combining LLMs and rule-based filters for instantaneous content screening. On the frontend, I utilized React, TailwindCSS, and DaisyUI to build a highly responsive, modern user interface backed by robust JWT authentication and role-based access controls.

• Natural Language SQL Query Interface

Combined data accessibility with artificial intelligence by developing an NLP-driven SQL generation engine using Python and LangChain. I addressed complex data-grounding challenges by designing schema-aware prompts and contextual guardrails, which reduced database execution errors by 40% and cut manual querying efforts by 60%. To bring this tool to non-technical users, I deployed an interactive, fluid web application via Streamlit and secured the infrastructure with tailored validation checks, successfully increasing database accessibility across teams by 50%.
