About Me

Dual degree student pursuing B.Tech Computer Science Engineering from Shiv Nadar University Chennai and B.Sc Data Science from IIT Madras with expertise in AI/ML. Experienced in developing multi-agent systems, risk assessment models, and data-driven solutions. Eager to step into the world of Data Science and learn more.

I specialize in building innovative AI solutions, from multi-agent systems to generative AI applications. My passion lies in creating intelligent systems that can solve real-world problems and make a meaningful impact.

Projects

Developed a machine learning model achieving 83% accuracy using ensemble methods including Boosting and Bagging. Implemented on large-scale datasets for content analysis using Python, Scikit-Learn, and LightGBM.

Python Scikit-Learn LightGBM Machine Learning

Built a multi-agent system with collaborative AI agents using MCP implicitly for tool integration along with hard coded tools. Integrated multiple AI providers (Groq, TogetherAI, Ollama). The entire system is orchestrated using LangGraph and operates based on a voting system by multiple agents and a reflection step for its validation of answers is included.
