About Sumanth Kumar

I’m a versatile engineer with nearly 4+ years of experience at the intersection of AI/ML and full-stack development. I’m currently pursuing my Master’s in Computer Science at Marist University while driving innovation as an AI/ML Researcher at Marist Poll, where I design and deploy Knowledge Graph-based RAG systems that transform how organizations traverse and query complex data.At Marist Poll, I built a Neo4j powered intelligence platform that combines graph traversal with FAISS vector search to boost answer accuracy by 40% for multi-hop polling queries. I also engineered autonomous ontology-construction pipelines that auto-generate Cypher queries via LLMs, cutting manual modeling effort by 60%, and deployed production-scale GraphRAG services for real-time insights. On the full-stack side, I leverage modern frameworks (React, Angular, Node.js/Express, and Spring Boot) to deliver responsive, scalable web applications, implement robust backend services, and optimize database schemas and indexing to reduce query times by 50%.What excites me most is creating intelligent systems that users can actually interact with. Whether I’m architecting autonomous agents with LangChain or delivering data-rich dashboards powered by graph analytics, I thrive on solving algorithmic challenges and building scalable solutions that deliver both technical innovation and exceptional user experiences.
