About Gautam Patidar

Senior Data & ML Engineer with 5+ years of experience building scalable, production grade data and machine learning systems.At Expedia Group, I design and operate distributed data pipelines processing terabytes of data daily across 50+ Airflow workflows. I’ve led performance optimizations reducing processing time by 30% and infrastructure costs by 20%, while improving system reliability by cutting downtime from 15% to 5% through resilient pipeline design.My expertise lies in building end-to-end data platforms and ML pipelines from large-scale batch/stream processing (PySpark, Airflow) to deploying ML systems and NLP-based applications (Transformers, FAISS, RAG).I focus on designing reliable, scalable systems that power real-world decision-making and customer-facing products.
