About Me

I’m a data engineer based in Dallas, TX, with a master’s in Data Science from the University of Maryland and a background in computer science, AI, and ML from SRM University. I enjoy building data systems that make it easier for teams to get the data they need and trust what they see.

My recent work has focused on scalable data pipelines and data quality. I’ve built pipelines with Python, PySpark, and AWS Glue, and used dbt and Snowflake to prepare data for reporting. At the UMD Counseling Center, I automated research data loads from six campus sources, cutting the wait for updated data from six hours to under 90 minutes.

I also enjoy working on applied machine learning projects. My research on deepfake detection earned a Best Paper Award at an international conference, and I placed in the top 10 out of 2,500 participants in a national computer vision hackathon while studying at SRM.

Sep 2025 – Present
  • Engineered PySpark and AWS Glue pipelines for multi-terabyte healthcare claims in S3, using EMR partitioning and Glue Data Catalog metadata to cut recurring batch runtime by 32% while verifying record totals against source extracts.
  • Modeled claims and eligibility marts in Snowflake using SQL and dbt incremental loads orchestrated via Airflow, reconciling member and provider keys across feeds so operations teams could run recurring reports 35% faster.
  • Built reusable claim-level feature tables in Python and Spark for payment-integrity models, working with data scientists on time-based training splits and null-handling rules to support 4 production fraud and overpayment experiments.
  • Developed a Python and Amazon Bedrock PR assistant that checks SQL/PLSQL changes against team quality rules and posts cited review comments in GitHub Actions, reducing manual database code review effort by roughly 60%.
  • Debugged complex SQL transformation failures and expanded pytest coverage using Cursor and Claude on masked claim samples, catching upstream schema drift early and reducing recurring source-to-target reconciliation tickets by 25%.
  • Automated AWS and Snowflake environment promotions with Terraform and GitHub Actions, separating dev and prod configs with documented rollback steps to cut manual release tasks in half across 8 scheduled pipelines.
  • Troubleshot late-arriving files, task failures, and SLA delays across Airflow and Glue workflows using CloudWatch, EventBridge, and Athena SQL, documenting root-cause runbooks that trimmed average on-call recovery time from 90 to 45 minutes.

Efficient Deep Fake Image Detection Using Dense CNN Architecture

International Research Conference on Computing Technologies for Sustainable Development (IRCCTSD 2024)
Communications in Computer and Information Science, vol 2361. Springer, Cham.

Deepfakes innovative manipulations of digital visual content using deep learning methods have emerged as a significant threat, raising concerns about misinformation and privacy violations. Their influence spans social media, political discourse, and beyond, highlighting the urgent need for robust detection tools. This research addresses the deepfake threat through a thorough examination of binary classification techniques. Focused on distinguishing genuine from manipulated images, the study leverages diverse datasets to train and evaluate methods utilizing Convolutional Neural Networks (CNNs) with emphasis on spatial feature extraction. Experimental results demonstrate the model's effectiveness in detecting manipulated images across various scenarios, achieving 97% accuracy on unseen data.
