As the leader of a dynamic team of 6 data scientists at Foxtel, I drive the utilization of data science capabilities to maximize ROI on marketing campaigns and empower Foxtel Resi and Foxtel Now businesses to make informed data-driven decisions.Key Contributions and Projects:1. Data Science Process Maturity Upgrade:Initiated and spearheaded a comprehensive review of existing data science processes, encompassing model development, continuous integration (CI), and experimentation. Identified areas for improvement and proposed strategic enhancements, resulting in the implementation of several recommendations. These improvements have elevated the team's efficiency and effectiveness, while additional enhancements remain in the pipeline for further optimization.2. Winback Model:Led the design, development, and deployment of a sophisticated winback model that accurately predicts the propensity of customers to return within the next 6 months after lapsing between T-18 and T-6. Overcoming the challenge of low winback rates and incorporating data from multiple time periods, this model achieved a significant uplift with a 2.6 times improvement in the top two ventils. This powerful predictive tool enables targeted winback strategies and drives customer retention effortlessly In addition to these achievements, I provide strategic leadership, mentorship, and guidance to the data science team. By fostering a collaborative environment and leveraging my expertise in data analysis, machine learning, and marketing analytics, I continuously drive innovative solutions that optimize marketing initiatives and facilitate data-driven decision-making processes.

I utilise he power of Machine Learning and Artificial Intelligence to automate manual processes in operation which in turn benefits customers in terms of saving time and cost along with reducing complexities around tedious processes. The data that we work with is mostly unstructured like texts and images etc.This role allows me to solve Machine Learning problems that are both complex and unique and hence provides me opportunity to use many different ML techniques including Text Classification, Entity Extraction models, NLP, Image Processing, Object Detection, OCR etc. Technical skills that i have improved on while being in this role are - Python, AWS, Google Cloud Platform, Django, Docker, Jenkins, Codefresh, CICD & Openshift .I am involved in end to end delivery of project starting from requirement understanding to solution design to implementation followed by deployment & maintenance.Key Contributions and Projects:Machine Learning Framework:Architected and developed a scalable machine learning framework based on a microservice architecture. This framework enables seamless integration of new ML pipelines while facilitating easy comparison against existing models. By leveraging this framework, the bank can optimize costs by paying only for the best-performing services, ensuring that customers always receive results based on historical accuracy.Entity Extraction from Unstructured Documents:Engineered a robust deep learning Named Entity Recognition (NER) model framework in PyTorch, capable of learning domain-specific entities. Leveraging the combined power of Convolutional Neural Networks (CNN), Recurrent Neural Networks (RNN), and Conditional Random Fields (CRF), this hybrid model achieves high-quality predictions. Model evaluation metrics demonstrated over 80% F1 score on two distinct domain-specific problems, enhancing the bank's ability to extract valuable information from unstructured documents effectively.
