About Arya Chakraborty

Data Scientist at TCS working with Westpac (one of Australia’s leading banks), designing and delivering AI/ML solutions that directly impact marketing efficiency, digital experience, and operations. My work spans traditional machine learning, Generative AI, NLP, and Computer Vision with a focus on measurable business outcomes.At WestPac, I build ML models that power customer-centric campaign analytics, enabling more precise and data-driven digital marketing campaigns. Delivered multiple GenAI POCs that significantly reduced manual effort for internal teams such as ~– Designed an AI-assisted query automation system that generates complex SQL for campaign workflows—cutting query development time from 2–3 days to just 2–3 hours, resulting in major productivity gains.– Co-built a Content Review & Tracking platform for business stakeholders, enabling automated monitoring of public-facing website content for compliance and updates. Contributed to NLP and Computer Vision use cases across a solution stack of 15+ AI modulesDeveloped a custom CV-OCR layer integrated into the bank’s mortgage application pipeline. This solution accelerated document processing, reduced friction for customers, and contributed to higher retention and quicker application turnaround.Previously, as an AI Developer at Isnartech Pvt Ltd, I led and delivered AI-driven products across multiple projects. I developed a full ERP solution with integrated AI capabilities, including automatic grading systems, food calorie estimation from images/videos, and NLP models that convert natural language queries into SQL. I also led a multidisciplinary team, combining hands-on model development with mentoring and delivery ownership.I hold an MSc in Data Science from VIT-AP University and a BSc in Statistics from the University of Kalyani. I’m particularly interested in applying AI and machine intelligence to BFSI use cases, where data and models can create tangible value in decision-making, risk, and customer experience.Tech focus: Machine Learning · Deep Learning · NLP · LLMs & GenAI · Agentic AI · Computer Vision · OCR · Python · SQL · Scikit-learn · PyTorch/TensorFlow · OpenCV · Azure · Databricks
