## About

I build data pipelines that actually hold up at scale\. Over the past 3\+ years as a Data Engineer at Riaktr, I've architected end\-to\-end Azure data platforms — designing Medallion Architecture \(Bronze–Silver–Gold\) on Azure Databricks, building ETL/ELT pipelines with Azure Data Factory and PySpark, and processing 5\+ TB of telecom data daily with 99% reliability\. What I care about: → Data that teams can trust — I built a quality framework that hit 99\.8% accuracy and cut incidents by 85% → Pipelines that are maintainable — reusable datasets, schema evolution, SCD Type\-2, CI/CD via Azure DevOps → Performance that scales — SQL tuning, partition pruning, broadcast joins, Iceberg time\-travel I work across the full stack: ADLS Gen2 · Azure Synapse · Apache Iceberg · Delta Lake · Airflow · Spark · PostgreSQL · MongoDB Before moving into data engineering, I spent 7 years in software engineering and QA at Cognizant and Seamless Distribution Systems — which means I think about reliability, testing, and stakeholder communication as naturally as I think about pipelines\. Currently open to remote Data Engineer roles where I can contribute to serious data platform challenges\.
