Reddit is a platform that fosters community and connection through discussions on countless topics.

• I've worked on several teams at Reddit and shipped many impactful ML models & data products to production.
• Ads Targeting ML
• Working on several ML based targeting models and products to improve how users are matched with advertisers at Reddit.
• We do full stack ML development and employ techniques from many different ML domains ranging from recommender systems, NLP and clustering / unsupervised learning / Nearest Neighbor search etc. to build and deploy impactful products.
• Ad Serving / Budget Pacing
• Implemented probabilistic pacing delivering X% in incremental ad revenue.
• Designed and built the budget split experiment framework to improve budget pacing algorithms.
• Worked on large scale real time streaming and batch processing pipelines to power Ad products in production.
• Ad Ranking
• Designed and implemented the first generation of machine learning models and model training pipelines for predicting CTR and ranking ads, which led to a ~X% increase in Ad CTR.
• Tech stack : Python, BigQuery, Jupyter, Scala, Spark, Spark Streaming, Go.

• Designed and added user features to unified machine learning feature store for use in ranking and recommendation algorithms.
• Part of a small squad that built Reddit's experimentation platform. My focus was on helping several product teams design experiments and managing the effort to provide an automated pipeline and user interface to evaluate experiments.
• Worked on many other projects involving user intent modeling and causal inference through supervised and unsupervised learning on large scale user data.
