Lead a team of data scientists (team size 7) to design, prototype, test, deploy and retrain predictive and prescriptive analytical models.
Developed and deployed a Generative AI chatbot using AWS Bedrock, integrating Claude Instant, Haiku, and Sonnet LLMs for comprehensive query handling.
Utilized Chainlit to create an intuitive GUI and implemented AWS Lambda functions for managing event-driven workflows, effectively fetching data from Amazon Redshift and logic from knowledge base.
Enhanced productivity by 20% through the innovative application of AI-driven root cause identification, improving operational efficiency and problem-solving capabilities.
Created predictive models using deep neural networks (DNN) with TensorFlow & Keras to forecast 4 critical quality parameters, achieving less than 10% MAPE during UAT for high consistency in production.
Implemented Feature Importance model using XGBoost and Random Forest algorithms to analyse intricate relationships between input and output variables and identify key factors influencing quality parameters, enhancing predictive accuracy and process optimization.
Utilized Graph Algorithms to map the hierarchy from raw material to final production output lab result, enabling comprehensive traceability and connection establishment within the production process.
Leveraged SHapley Additive exPlanations (SHAP) to enhance model interpretability by quantifying the impact of each input variable on the model's predictions, facilitating better understanding and transparency.
Worked directly with business partners to develop, communicate and execute the projects and provided strategic direction and took accountability for requirements, procedures and standards.
Developed solutions that bring critical insights to wide scale of different problems such as targeting customers and segmenting markets, product design, marketing optimization, demand forecasting and brand valuation, profit and price analyses and fraud detection.
Implemented advanced statistical analyses identifying trends, and exploring opportunities with the aim of generating actionable insights.
