Azure Data Factory, Synapse, pipelines
Master Databricks Secret Scopes with the safe analogy that makes it click. Complete setup guide: Key Vault creation, secret storage, scope creation via URL, granting AzureDatabricks App ID access, testing, and the config notebook pattern. Covers the #1 permission error fix, multiple environment scopes, Key Vault-backed vs Databricks-backed comparison, and security best practices.
Master reading and writing every file format in Databricks. Standard CSV, pipe-delimited, single-quote qualifiers, escape characters, multiline values, JSON, Parquet, and Delta Lake. Covers all CSV options, writing with partitionBy, managed vs external tables, Delta operations, and a complete read-transform-write pipeline.
Master every method to connect Azure Databricks to storage. Access Key (dev), SAS Token (scoped), Service Principal with OAuth (production), and Unity Catalog with Access Connector (enterprise). Covers abfss vs wasbs, mounting vs direct access, Key Vault secret scope setup, config notebook pattern, and common connection errors.

Master Azure Databricks from architecture to daily commands. Covers workspace setup, cluster types, notebooks, and every dbutils module: fs (file operations), secrets (Key Vault integration), widgets (parameterization), and notebook (orchestration). Plus Delta Lake operations, mounting storage, Workflows, cost management, and Databricks vs Synapse comparison.
Build a production-grade pipeline combining data quality (null handling, standardization, deduplication) with dual SCD Type 1 and Type 2 using Synapse Data Flows. Dual hash columns, four-stream Conditional Split, three sinks, complete audit trail. Every transformation explained with the hospital intake analogy.

Master Azure networking for data engineering. VNets, Subnets, NSGs (inbound/outbound rules), Private Endpoints, Service Endpoints, VNet Peering, VPN Gateway, ExpressRoute, DNS, and production network architecture. Complete city analogy makes every concept click.
Master the differences between databases and data warehouses, OLTP vs OLAP, normalized vs star schema, row vs columnar storage. Plus detailed Dedicated vs Serverless SQL Pool comparison with cost calculations, decision framework, and real-world scenarios.
Build a complete SCD Type 2 pipeline using Synapse Data Flows. Every transformation explained: hash generation, lookup, conditional split, parallel expire+insert paths, dual sinks. Includes surrogate key strategy, first-run vs subsequent-run walkthroughs, point-in-time queries, and common errors.
Build an SCD Type 1 pipeline with SHA-256 hash-based change detection using Synapse Data Flows. Every transformation explained: Source, Derived Column (hash), Select (SRC_ prefix), Lookup (left outer), Conditional Split (new/changed/unchanged), Alter Row (insert/update), Union, and Sink. Includes audit trail design, idempotency, and first-run vs subsequent-run walkthroughs.
Build a complete SCD Type 1 pipeline from scratch with every activity explained. Covers Lookup, ForEach, Copy, audit logging with stored procedures, parameterized datasets, the complete parameter flow chain, date-partitioned output, and the restaurant kitchen analogy that makes it all click.
