About

Final-year CSE student at IIIT Kota. I like building things that ship and solve real problems. Currently an SDE Intern at Cashfree Payments, where I've built AI agents, MCP servers, and developer tooling that are now used company-wide, turning hours of manual work into 30-second Slack queries. One of my projects was showcased at the Global Fintech Fest. Previously at Bhejooo, where I worked on distributed integrations and logistics automation, improving system reliability and operational efficiency. I love building things that matter, from autonomous agents to full-stack platforms, and thrive at the intersection of AI, system design, and developer-facing products. Recently, I built AI-Career Hub, a personalized career guidance platform powered by AI, helping users discover career paths through skill assessments and resume intelligence. I also enjoy competitive programming and have solved 750+ DSA problems and earned notable recognitions like Amdocs GenAI Hackathon 2024 Winner and Amazon ML Summer School’24 selectee. Always exploring new ideas, new technologies, and new ways to push what’s possible.
