Senior Cloud Data Engineer & Architect with 15+ years of experience designing, modernizing and implementing enterprise Data Warehouse, Lakehouse and cloud data platforms. I specialize in Microsoft Azure, Databricks, Microsoft Fabric and Snowflake, combining strong architecture expertise with hands-on engineering and delivery.

I have extensive experience delivering business-critical data solutions for leading organizations in banking, financial services, energy, retail and travel, including projects for Deutsche Bank, Deutsche Börse, Commerzbank, Uniper, ALDI SÜD and HRS.

Core Expertise:

Cloud Data Architecture
  • Enterprise Data Warehouse & Lakehouse architecture
  • Azure and cloud data platform modernization
  • Microsoft Fabric architecture and migration
  • Databricks Lakehouse solutions
  • Snowflake Data Warehouse & ELT architecture
  • Data modeling and scalable data-platform design

Data Engineering & Integration
  • Azure Data Factory (ADF) / Fabric Data Factory
  • Azure Databricks, PySpark & Python
  • Microsoft Fabric
  • Snowflake & SnowSQL
  • dbt
  • Apache Airflow
  • Azure Synapse Analytics
  • SQL Server
  • SAP HANA / SAP data integration
  • REST API and enterprise application integration

Modernization & Migration
  • Legacy DWH/ETL to modern cloud platforms
  • ADF and Azure workload modernization
  • Migration of orchestration workloads to Apache Airflow
  • Design of reusable ingestion and transformation frameworks
  • Batch and API-based data integration
  • Performance and cost optimization

I work across the complete data-platform lifecycle: requirements analysis, architecture, technology selection, data modeling, ingestion, transformation, orchestration, implementation, testing, CI/CD, performance optimization and production support.

My strength is bridging architecture and hands-on engineering. I can define the target architecture and technical standards while also working directly with SQL, Python, PySpark, Databricks, Snowflake, Fabric, dbt and Airflow to implement the solution.

Having worked for many years on complex projects in Germany, I am experienced in enterprise environments with demanding requirements around data quality, reliability, scalability, security and maintainability.

I am particularly interested in projects involving:
Azure Data Platforms | Databricks | Microsoft Fabric | Snowflake | Cloud DWH | Lakehouse | Data Platform Modernization | Data Architecture | Data Engineering | dbt | Airflow | PySpark | SAP-to-Cloud Integration

for Data Migration and Data Integration Projects.

Projects:
#1 Retail Banking - Postbank Savings Deposit Accounts Migration

This project involves migration of savings account
deposits data from Mainframe IBM Z/OS systems to SAP
Deposit Management application using PowerCenter 9.1 HF
1 and Power exchange 9.1. This involves reading data
from flat files, mainframe data sets, oracle and
writing data into flat files which will be then
uploaded into SAP Deposit Management application. Power
exchange 9.1 was used for the connecting to mainframe
and reading of Mainframe data sets. ETL Informatica
PowerCenter 9.1 was used for the extraction,
transformation, and loading of data into the target
systems. The project had only single load i.e. one time
migration. This project involves data extract,
transformation and loads of 250 to 500 million records.

#2 Retail Banking - Postbank Savings Deposit Accounts Integration
This project involves integration of savings deposit
account data from SAP, Mainframe systems in to the
Oracle enterprise data warehouse.
ETL activities includes loading of this data into
Oracle enterprise data warehouse used for Retail
banking reporting in Deutsche Bank, Germany. ETL
Informatica PowerCenter 9.1 HF 1 was used for the
extraction, transformation, and loading of data into
the target systems. The project had several loads like
Daily Loads, Weekly Loads, Monthly Loads, Quarterly
Loads, and YTD Loads. These loads were implemented
using Incremental Loading (Change Data Capture), and
Slowly Changing Dimension Mappings. This project
involves data extract, transformation and loads of 30
to 50 million records.

#3 Retail Banking - Auto Deployment
Deutsche Bank started this project to save huge time
for deployment of all ETL components e.g. informatica
PowerCenter workflows, informatica powerexchange data
maps, parameter files, shell scripts,etc. This project
helped Deutsche Bank to save time spend by deployers in
deploying multiple environments, error free deployments
and hence reduce cost.
