Myntra

Software Engineer - Data Science
  • Sentient - The project involves using NLP models on textual and speech data incoming at the customer care center and surfacing customer pain points, anomalous service breakdowns and pre-order questions which can lead to 'escalations'. The use cases are aimed at preventing churn and improving customer redressal.
  • Churn driver analysis - Worked on developing a causal model for churn scores. This model helped the revenue and marketing team identify major drivers for churn leading to the implementation of a more targeted customer retention strategy.
  • Return item quality predictor model - The target feature recognizes an abused return item and helps Myntra decide whether to do 'Inward Quality Check (IQC)' or not - hence, saving on cost and manpower and reducing average return refund time by half. Contributed by engineering features and developing tool for evaluating model performance across service and revenue parameters
  • Pained customer redressal framework - Quantified the impact on customer transaction frequency due to various service/experience short-falls. On the basis of which designed a framework for redressing pained customers and improve customer retention.
    • Developed a near real-time unit-level pendency report across  forward and return supply chain nodes to provide insight into service breakdowns and improve resolution time.
    • Designed models to ascertain the impact of vendor de-listing on metrics like overall delivery time, returns percentage and Myntra-initiated-cancellations
