Staff ML Scientist @ Etsy | Ex-Staff MLE @ Shopify | Founding MLE @ HubSpot AI | CS @ Georgia Tech
www.mukulsurajiwale.com Staff Machine Learning Engineer with 9+ years of experience building and scaling end-to-end machine learning systems in Python, using tools like TensorFlow, PyTorch, Keras, Scikit-learn, and Hugging Face Transformers. I’ve led high-impact projects across the full machine learning lifecycle, from problem framing and data collection to model development, deployment, monitoring, and continuous improvement. I enjoy solving meaningful non-trivial problems at the intersection of research and application and love building things from zero to one with likeminded mission-driven people who care deeply about the societal impact of their work. Currently, I am working at Etsy as a Staff Machine Learning Scientist. Before Etsy, I worked at Writer, where I led the development of a next-generation multimodal, agentic, vision-based information retrieval system to enable accurate natural language QA. Before Writer, I was a Staff Machine Learning Engineer at Shopify, where I led applied research on LLMs and information retrieval for e-commerce. Before Shopify, I was a founding member of the Artificial Intelligence group at HubSpot, where I rose to become the most senior IC MLE and helped grow the team from 5 to XX+ members. My work covers the following: - Training and deploying LLMs for multimodal information retrieval and QA. - Building LLM fine-tuning, evaluation, and serving layers for HubSpot’s ML-Ops platform - Fine-tuning and serving LLM models for specific use case using SFT and DPO - Real-time streaming anomaly detection and forecasting on time series data - LLM-based topic detection in conversations - Bayesian Active Learning - Markov chains for user action prediction - Text classification, clustering, and similarity - Search: semantic retrieval, ranking, and performance monitoring - Contextual multi-armed bandits for adaptive A/B testing - De
