  • Worked on L1 & L2 list page ranking models, Ad ranking models, product list page personalisation & LLM use cases at Myntra.
  • Worked on an ML model for the L2 Ranking Layer, aimed at real time re-ranking top products based on user preferences. The model incorporates user & product embeddings, in-session features, and dynamic product features, optimising for CTR. Resulted in significant uplift in business metrics
  • Created a machine learning model for user-attribute recommendation, utilising a custom implementation of Bayesian Personalized Ranking (BPR) in Tensorflow with a weighted loss function and improved negative sampling techniques. Led to ~8% nDCG uplift. Also explored alternative models like LightFM, NCF & DeepFM.
  • Runner-up prize in the Myntra Hackathon - Built an MVP for personalised banner creatives on Myntra's homepage.

  • Designed and implemented a location-based recommendation system utilizing BPR model to learn location embeddings, which are subsequently employed in multiple downstream tasks (L1 ranking model, Trending near you). Led to significant uplift in revenue.
  • Conducted experiments with frameworks like Nvidia's Triton and ONNX for scaling machine learning model serving and deployment.
  • Implemented an improved diversity layer optimising for maximal marginal relevance (MMR) in the ranking pipeline.
