Azure Data Factory, Databricks, Microsoft Fabric and Snowflake pipelines — plus the Power BI layer on top. SAP, Epicor, Salesforce and NetSuite already synced to Azure. 5+ years in Azure data engineering. I scope, build and hand over the whole path: source system → ingestion → ETL/ELT into a Medallion Lakehouse (Bronze, Silver, Gold) → semantic model → the dashboard your team actually opens. Most projects reach me one of four ways: - No data platform yet — spreadsheets, an app database, and numbers people need every week - A legacy platform that needs moving to Microsoft Fabric, Azure or Databricks - An ERP or CRM that won't talk to your warehouse — SAP, Epicor, Salesforce, NetSuite and QuickBooks are ones I've already wired to Azure - Month-end reporting that takes three days and still doesn't reconcile 🔧 What I build ✅ New data platforms from scratch — empty Azure subscription to first working dashboard ✅ Azure Data Factory and Microsoft Fabric pipelines — OneLake, Lakehouse, Warehouse, Notebooks ✅ Azure Databricks, Apache Spark and Delta Lake processing at scale ✅ ETL and ELT development, including incremental and metadata-driven patterns ✅ Data warehouses, Lakehouse architectures and dimensional data models ✅ API, ERP, CRM and SQL database integrations ✅ Legacy platform migrations to Microsoft Fabric, Azure and Databricks ✅ Power BI dashboards, semantic models and DAX ✅ Data quality, validation, monitoring, and cost and performance tuning 🛠️ Stack Microsoft Fabric · Azure Data Factory · Azure Databricks · Azure Synapse Analytics · Azure SQL Database · Snowflake · BigQuery · SAP Python · SQL · PySpark · DAX SQL Server · PostgreSQL · MySQL Power BI · Tableau · Looker Studio 🤝 How I work ✅ A written build plan before any code — scope, sequence, and what "done" means ✅ Pipelines ship with logging and failure alerts, not just a green run on my machine ✅ Handover documentation, so your team can run it without me ✅ 4+ hours of daily overlap with US business hours (I'm UTC+5:30) 📩 Send me your source list and the one report that keeps breaking. I'll come back with a pipeline plan, a rough timeline, and an honest answer about whether Microsoft Fabric is the right target for you.

Microsoft Azure & Data Engineering I have extensive experience architecting and delivering production-ready data solutions within the Azure ecosystem and Microsoft Fabric. My background includes the end-to-end development of high-performance Lakehouse architectures, where I’ve utilized Fabric Pipelines and ADF to orchestrate complex data flows. I have a proven track record of provisioning secure infrastructure—from ADLS Gen2 to Azure SQL Databases—and building parameter-driven ingestion frameworks that handle diverse data sources. By integrating Logic Apps and WebHooks, I’ve successfully implemented automated monitoring systems that ensure 24/7 data availability and rapid incident response, providing a seamless flow from raw ingestion to analytics-ready Gold layers. Azure Databricks & Apache Spark I have a deep technical background in solving big data challenges using Azure Databricks and PySpark. I have successfully implemented Medallion Architectures (Bronze, Silver, Gold) to transform raw, unstructured data into optimized Delta tables for advanced analytics. By leveraging Analytical Functions and fine-tuning Spark cluster configurations, I have significantly reduced data processing windows for large-scale datasets. By optimizing cluster configurations and utilizing Analytical Functions, I significantly reduce processing windows and compute costs. I specialize in bridging the gap between raw data lakes and business intelligence, ensuring that data is partitioned, indexed, and optimized for downstream consumption. My focus is always on creating a high-performance "Single Source of Truth" that allows BI tools to pull insights with minimal latency. Informatica Intelligent Cloud Services (IICS) As an IICS Data Integration Specialist, I build high-concurrency ETL/ELT solutions that act as a bridge between diverse enterprise ecosystems. I have extensive experience developing complex mappings to extract high-volume data from Salesforce (SFDC), Oracle, and SQL Server, transforming it for delivery into Azure , AWS environments and Snowflake. My approach focuses on maximizing throughput and ensuring data integrity through advanced transformation logic, reusable mapping tasks, and standardized error-handling frameworks that support global business requirements. Informatica PowerCenter & Legacy Modernization With a deep background in Informatica PowerCenter, I specialize in the full SDLC of enterprise data warehousing, from star-schema design to production deployment. I have a proven track record of optimizing legacy workflows by re-engineering complex mappings and sessions using PL/SQL and Unix Shell Scripting for maximum efficiency. My core strength is modernizing these legacy footprints—moving global organizations from traditional on-premise ETL to agile, cloud-integrated architectures without interrupting business-critical operations. Multi-Cloud Data Engineering I have a proven track record of managing complex data ecosystems across Azure, AWS, and SaaS platforms (Salesforce/IICS). My approach is rooted in DataOps, where I automate the end-to-end orchestration of data pipelines to eliminate manual intervention and reduce human error. I have built resilient systems using configuration-driven triggers, cross-cloud authentication, and Unix scripting to ensure secure, seamless data flow between providers.
