## Headline

Senior SWE @Arcana \| ex\-Graviton \(HFT\) \| AI/ML Inference \| Distributed Systems \| IIT Patna Silver Medalist

## About

Broad interests: Startups, Distributed Systems, Optimization, Machine Learning, Quantitative Finance Obsolete: I currently work as a Software Engineer at Graviton, a leading HFT firm\. Prior to this, I had joined UnifyApps at seed stage while it was still a 50\-ish person team\. As an early AI/ML Engineer, I worked on the core ML infrastructure and orchestration harness for AI agents\. During my undergrad at IIT Patna, I have contributed to ML research, focusing on areas such as Representation Learning and Multimodal Learning, with first\-author publications in prestigious international conferences\. My research and project experience extend to Information Retrieval, Ranking Systems, and Large Multimodal Models\. An avid problem\-solver, I have excelled in competitive programming contests such as ICPC, Meta Hacker Cup, and Google Kick Start\. I take a keen interest in exploring topics related to Probability, Randomness, and Contemporary Philosophy\.
