Hi, I'm Jonathan Wandera — A Data Architect, Designing Scalable Data Platforms, Warehouses & Analytics Systems.
I specialize in designing and building modern data platforms that power analytics, machine learning, and business intelligence at scale. My work focuses on building reliable data pipelines, scalable data warehouses, and well-modeled datasets that enable organizations to make confident, data-driven decisions.
With experience across the modern data stack, I design architectures that support large-scale ingestion, transformation, and analytics workloads. My work includes building batch and streaming pipelines, implementing dimensional and enterprise data models, and enabling self-service analytics across organizations.
I am particularly passionate about data platform architecture, data modeling strategy, and building systems that make high-quality data accessible to engineers, analysts, and machine learning teams. My focus is always on delivering measurable business impact through scalable and maintainable data systems.
“Transforming complex data ecosystems into reliable, scalable platforms that unlock real business value” is my motto
