Profile
AI engineer building deployable AI systems, agentic workflows, and organizational adoption in regulated and large-scale environments. Currently Head of AI at DreamStreet, building compliance-aware AI architecture for investor and trader workflows across research, brokerage, and advisory domains. Previously led applied AI research at Dream Sports / Dream11, including a Columbia University research-center collaboration, cross-continent teams across India and New York, and production ML systems at 250M+ user scale.
Particularly interested in AI harness design, developer productivity, and turning emerging model capabilities into reliable workflows and products.
Education
M.S. in Data Science — University of Rochester · Rochester, NY
Bachelor of Technology — Indian Institute of Technology, Roorkee · Roorkee, IN
Experience
Head of AI — DreamStreet · Mumbai
- Designed a compliance-aware orchestration framework for multi-step LLM agents in a SEBI-regulated financial setting — constrained tool-use, guardrail/policy enforcement, and end-to-end audit logging for controllability and traceability of agent decisions.
- Deployed self-hosted open-source language models (Qwen 3.5 / 3.6 27B) with vLLM and an agent-tooling stack across on-prem, GCP, and AWS.
- Built Hermes-based self-serve agents for in-house productivity — domain research reviews, alerts, and similar tasks — across Marketing, Finance, IT, Tech, and HR.
- Built full-stack AI for investor and trader workflows across research, brokerage, and advisory, and drove organization-wide AI adoption through training, rapid prototypes, and agent-centric workflow redesign.
Senior Principal Research Scientist / Head of Applied Research — Dream11 (Dream Sports) · Mumbai & New York
- Headed applied AI research for Dream Sports and built a high-performing cross-continent team of research scientists, applied scientists, and ML engineers across India and New York.
- Established and led an industry–academia research partnership and research center with Columbia University, NY — co-defining research agendas at the intersection of ML and sports analytics and supporting joint work with faculty, post-docs, and PhD students.
- Defined a multi-year applied-research portfolio — ~23 candidate research problems, 10 funded over two years — spanning sports robotics, LLM-based persona/behavior simulators, and agentic evaluators for personalization.
- Developed deep-learning models for early churn prediction from large-scale user–product interaction time series (ICMLA 2023) and LLM-based behavioral simulation of user lifetime trajectories at population scale (250M+ users).
- Built distributed recommendation, semantic similarity search over ~100M entities, and feature infrastructure for 250M+ users — seeding publications on personalization (UMAP ‘25, ECML-PKDD ‘25) and entity resolution (ACL 2026).
- Designed a real-time probabilistic forecasting system producing 50k+ concurrent forecasts under strict latency constraints for production ML applications.
- Delivered regular data, ML, and AI training across Dream Sports (audiences of ~10 to 200) and co-led Sports × AI sessions at Columbia for students, post-docs, and faculty.
Staff Data Scientist — David H. Smith Center for Vaccine Biology and Immunology, University of Rochester · Rochester, NY
- Built automated, self-serve ML systems for bio-imaging research, including 3D reconstruction from hyperspectral microscopy — contributing computational methods to immunology research published in Cell Reports and the Journal of Immunology.
- Automated ultrasound Doppler-angle estimation using deep neural networks (EMBC 2019).
Data Scientist — AXA Insurance · Pune
Built survival / mortality-forecasting models and scaled statistical pipelines (Spark, Python) for the US population (~300M+ entities).
Data Analyst — AbsolutData Research & Analytics · Gurgaon
Developed a multi-stage predictive-maintenance model fusing sensor telemetry, oil-analysis, and human-labeled alerts.
