Principal Financial
Data Scientist
Dec 2024-Present | TX
Key Achievements
- Developed an XGBoost-based credit risk model for consumer lending, improving default prediction accuracy by 19% and reducing portfolio-level loss estimates by $2.4M annually after full deployment.
- Created a scalable time-series forecasting solution using Prophet for insurance claim volumes, reducing forecast deviation from actuals by 14% and helping actuaries adjust monthly reserve estimates more accurately.
- Automated quarterly regulatory reports using Apache NiFi, SQL, and Python scripts, reducing manual data processing time by 38 hours per quarter and minimizing risk of compliance errors.
Mphasis
Data Scientist
Jun 2022-Dec 2023 | India
Key Achievements
- Built BERT-based NLP models for automated contract clause classification, reducing manual document review time by 41% and increasing extraction accuracy on edge cases by 18% across 20,000+ documents.
- Designed monitoring dashboards using Power BI to track live model metrics for 15+ client projects, reducing SLA violations by 27% and enabling proactive alerts for data drift or pipeline errors.
- Developed a Python and SQL-based A/B testing framework that supported over 200,000 daily users and allowed marketing teams to evaluate conversion changes with 95% confidence in under 48 hours.
- Processed real-time financial transactions using Spark Structured Streaming and Apache Kafka, reducing anomaly detection latency by 3.2 seconds and supporting immediate transaction flagging for review.
Ascent Soft Tech
Data Analyst
Jun 2021-May 2022 | India
Key Achievements
- Analyzed transactional and behavioral data from five SME clients to identify workflow bottlenecks, leading to a 9% reduction in task processing times after targeted changes to internal tooling processes.
- Designed monthly Tableau dashboards for C-level reporting on KPIs like churn, CAC, and LTV, decreasing manual reporting time by 80% and improving internal visibility for decision-makers.
- Built complex SQL queries integrating relational and NoSQL data sources across PostgreSQL, MongoDB, and Redis to support seven key weekly reports for sales, operations, and product teams.
- Created DAX-powered Power BI dashboards to monitor internal helpdesk ticket resolution times, which helped reduce open ticket aging beyond SLA by 36% within two quarters.
Featured Projects
Innovative solutions that demonstrate expertise in machine learning and data engineering
A/B Testing Analysis
This project focuses on analyzing the results of an A/B test to determine if a new webpage design leads to a higher conversion rate. It includes hypothesis testing, statistical analysis using Python, and a recommendation on whether to launch the new design.
Customer Churn Dashboard
An interactive dashboard built with Tableau to visualize customer churn. This project involves data cleaning, feature engineering, and creating KPIs to identify key factors contributing to churn, enabling stakeholders to make data-driven decisions to improve retention.
Real-Time Data Pipeline
This project demonstrates the construction of a real-time data streaming pipeline using Apache Kafka, Spark Streaming, and a database like Cassandra. It is designed to process, analyze, and store data with low latency for immediate insights.
