Professional Summary
Machine learning engineer with 5 years of experience building and serving recommendation and search models for an e-commerce marketplace with 9 million monthly users. Owns the path from feature pipelines to low-latency serving on Kubernetes, and has shipped ranking models that raised add-to-cart rate in A/B tests. Strong in Python, PyTorch, Spark and MLOps.
Work Experience
Machine Learning Engineer II
2022 – Present
Kartly Commerce
- Built and shipped a two-tower retrieval model and a gradient-boosted re-ranker for product search; the A/B test showed a 7% rise in add-to-cart rate.
- Served models with Triton on Kubernetes at 3,000 requests a second with p99 latency under 40 ms.
- Moved training from notebooks to scheduled Airflow and Kubeflow pipelines with MLflow tracking, so models retrain weekly instead of quarterly.
- Added drift and data-quality monitoring that caught a broken price feature within an hour instead of days.
Data Engineer
2020 – 2022
Vaani AI Labs
- Built Spark pipelines that prepare 2 TB of speech and text data a week for model training.
- Created the feature store tables used by 4 data scientists, ending duplicated feature code.
- Cut the nightly pipeline's cloud cost by 35% by moving to spot instances and partitioned Parquet.
