Senior Data Warehousing & Analytics Engineer | AWS | ETL | SQL

I am a Senior Data Warehousing & Analytics Engineer with 10+ years of professional experience designing, building, and operating scalable data warehouse and analytics platforms for enterprise and real-world use cases. I specialize in AWS-based data architectures, building end-to-end data pipelines using S3, Lambda, Glue, and Athena, with a strong focus on SQL-driven transformations, data modeling, performance optimization, and cost-efficient cloud design. My background spans telecommunications, finance, energy, and sustainability-focused projects, combining enterprise reliability with modern cloud-native practices. In recent work, I designed and implemented a production-grade AWS data warehouse to analyze weather forecasts, solar generation, and rain collection data for sustainable farming operations in Ghana. This included automated ingestion, transformation, and analytics pipelines, infrastructure-as-code (Terraform), and monitoring, all built with a strong emphasis on maintainability and low operating cost. Previously, I worked with Capgemini Germany, supporting and operating mission-critical BI and data warehouse platforms for enterprise clients. I progressed from 2nd-level support to 3rd-level support and team leadership roles, gaining deep experience in incident management, SLA-driven environments, performance tuning, and stakeholder communication. I am comfortable working fully remote, collaborating across time zones, and integrating into existing teams or taking ownership of end-to-end data solutions. I value clean design, clear documentation, and pragmatic solutions that deliver measurable business value. What I can help you with: -AWS data warehouse & analytics platform design -ETL / ELT pipeline development (SQL & Python) -Data modeling (fact & dimension tables) -Cloud cost optimization & performance tuning -Analytics-ready data for BI & reporting -Long-term platform support and improvement If you are looking for a senior, reliable data engineer who can design, build, and operate cloud data platforms — not just experiment with them — I’d be happy to discuss your project.
