About

Hi! I am Arjun Sehajpal. I ply my trade as a Staff Machine Learning Engineer at Visa, where I’m building a centralized AI platform that integrates open-source monitoring tools and governance APIs, enabling automated fairness, explainability, and model catalogue workflows.

Before this, I spent almost five years at ZS across roles in Data Science and AI Engineering. My work there focused on designing and engineering AI/LLM systems, which included developing internal ML libraries, improving reproducibility and experimentation, and personalization systems.

Prior to ZS, I worked at Pluto7 as a Data Scientist on Demand Forecasting and Supply Chain Optimization use-cases using time-series modelling and scalable data pipelines.

I’ve mostly worked on structured data systems and ML system design, and have steadily moved deeper into LLMs, infrastructure, and AI engineering.

Outside work, I spend my time reading, practicing yoga, and slowly becoming a calmer, more deliberate person.
