Developing an agentic pipeline that turns product briefs, CAD files, and reference videos into editable 3D technical animations using LangGraph, Python, and Blender. Designed a fail-closed quality loop with exact geometry checks and vision-language model review, and instrumented the pipeline with LangSmith for traceability.

Launched the Compliance Defects Platform as principal architect for a team of 8 data scientists and ML engineers, replacing a proprietary-LLM and rule-based system with an open-weight multimodal system. Designed a two-stage funnel with two-tower multimodal embeddings and fine-tuned small open-weight language models, and defined a risk-tiered evaluation framework adopted as the release gate.

Launched the expert-matching system for the Virtual Expert Platform, cutting allocation time by more than 50%. Built graph neural network features for the matcher and ran A/B tests that improved customer NPS by 5 points.

Built the multimodal ad-policy detection system for Sponsored Products, combining image models, vision-language models, and language models to flag policy-breaking ads, cutting policy defect rates by 30% year over year. Launched the moderation flow for the Brand Posts ad program and led cross-organizational initiatives across multiple ML teams.

Launched the attribute extraction platform that reads catalog photos and tags product attributes automatically, scaling to over 80% of categories at 90%+ accuracy. Architected the shared image-understanding foundation behind search, similar-product recommendations, and automatic description generation, and led a team of 5 ML engineers and data scientists.

Developed churn prediction and next-best-product recommendation systems for enterprise telecom clients.

Developed buyer propensity modeling and cross-sell optimization for retail loyalty programs.

Built ETL pipelines and CRM data workflows.

M.Tech in Statistics and Operations Research (QROR) from Indian Statistical Institute, Kolkata, completed in 2012.

Bachelor of Engineering in Chemical Engineering from Jadavpur University, Kolkata, completed in 2007.
