KenyaWhat I'm looking for
I am a data engineer and data modeler with 2+ years designing and implementing physical data models and production-grade pipelines across banking, retirement planning, and insurance domains. I build metadata-driven ETL/ELT frameworks, automate ingestion/validation/loading, and create analytics-ready models using tools like ERStudio, SSIS, Git, CI/CD, and SQL/PL/SQL.
I have hands-on experience supporting modern cloud and big data ecosystems including Azure Synapse, Azure Data Factory, Databricks (PySpark/SparkSQL), Snowflake, and GCP BigQuery. I have delivered domain-federated enterprise data warehouses using the Medallion Architecture, implemented CDC/MDM strategies, authored source-to-target mappings and data dictionaries, and completed over 40 development stories for conformed silver-layer entities.
I collaborate closely with data modelers, solution architects, ETL/API teams and business stakeholders in Agile environments to deliver scalable pipelines, automated jobs, performance tuning and end-to-end documentation. I am committed to delivering maintainable, well-documented data solutions that support governance and downstream analytics.
