I don't just move data from A to B — I build systems that stay reliable when requirements change, data volumes grow, and edge cases appear at 2am. As a Data Engineer, I've built production-grade pipelines on Azure Databricks using a 4-layer Medallion architecture processing real IoT asset data across enterprise trade channels. I've implemented Delta Live Tables with streaming ingestion, SCD Type 1 CDC deduplication, and Databricks Workflows orchestration — the kind of infrastructure that doesn't just work on day one, but holds up six months later. What I care about: pipelines that don't need babysitting. Schemas that survive upstream changes. Alerts that fire when something actually matters. I think about data quality at the layer it enters, not after it's caused a problem downstream. I've also gone beyond pure engineering — I integrated a LangGraph AI analyser into a live data pipeline with multi-channel alerting (Teams, Email, WhatsApp), which means I understand where data ends and intelligence begins. My stack: Python · PySpark · SQL · Delta Live Tables · Azure Databricks · ADLS Gen2 · Power BI · Tableau I'm early in my career but not early in my thinking. If you want someone who asks "what happens when this breaks?" before they write the first line of code — let's talk.
