## About

I build data systems that businesses rely on — pipelines that don't break, lakes that scale, and warehouses that answer questions fast\. Over the past 3\+ years at Cognizant, I've worked end\-to\-end across the AWS data stack — designing ETL/ELT pipelines from scratch, architecting Medallion data lakes, optimizing Redshift performance, and automating workflows that used to require constant manual intervention\. A few things I'm proud of: Maintained 99\.5% pipeline uptime across production environments by building robust Airflow monitoring, retry logic, and SLA controls Cut data processing time by 55% through full ETL automation on high\-volume sales data across regional markets Reduced Redshift query time by 20% \(45s → 36s\) using distribution key tuning, sort key optimization, and query rewriting Improved churn model accuracy to 87% by engineering clean, leakage\-free training datasets from 10M\+ daily records My progression has mirrored the complexity of what I've built — starting with execution\-focused pipeline work and growing into full data lake architecture ownership, including Medallion \(Bronze/Silver/Gold\) design, Glue Crawler configuration, and WLM tuning in Redshift\. I'm passionate about data reliability — making sure the numbers that reach analysts, dashboards, and ML models are clean, timely, and trustworthy\. Core stack: Python · PySpark · SQL · AWS Glue · Amazon S3 · Amazon Redshift · Apache Airflow · AWS Lambda · Delta Lake Open to Senior Data Engineer and Data Platform Engineer roles where I can own architecture, not just maintain it\. 📩 akkrish000@gmail\.com \| 📞 \+91 73390 33973
