Hi, I’m a Senior Data Engineer with 8+ years of experience I design, build, and optimize reliable, scalable data pipelines that power analytics, reporting, and business decision-making. I work with modern data stacks like Databricks, Delta Lake, Snowflake, SQL, and Python, and I bring a strong data-quality mindset so pipelines don’t just run — they produce trusted data. 🔹 What I Do as a Data Engineer ✅ End-to-End ETL / ELT Pipeline Development – Source → Bronze → Silver → Gold (Medallion Architecture) – Batch & incremental data loads – Schema evolution handling ✅ Incremental Loads, CDC & SCD (Type 1 & Type 2) – MERGE-based upserts – History tracking & effective dating – Late-arriving data handling ✅ Databricks & Delta Lake Engineering – Optimized Spark jobs (partitioning, caching, Z-ORDER) – Delta Lake ACID transactions – Performance tuning for large datasets ✅ Snowflake Data Engineering – Efficient table design – Query & storage optimization – ETL integration & analytics readiness 🔹 Data Quality Built In (Not Bolted On) Unlike many engineers, I validate data as part of the pipeline, not as an afterthought: Row-level reconciliation Null & duplicate checks Schema drift detection Dev → Stage → Prod consistency This means fewer production issues and more reliable dashboards. 🔹 Tech Stack • SQL (advanced, performance-tuned) • Python, PySpark • Databricks, Delta Lake • Snowflake • ETL / ELT frameworks • Medallion Architecture • Data Warehousing concepts 🔹 How I Work ✔ Clean, maintainable code ✔ Clear documentation ✔ Production-ready pipelines ✔ Ownership mindset
