Hi, my name is
Bob Otieno Okech.

I help businesses visualize their data.

I’m a Business Intelligence Developer and Data Engineer passionate about transforming complex data into clear, actionable insights for startups, business teams, and non-technical stakeholders. I specialize in designing scalable, end-to-end data solutions covering everything from data ingestion and ETL/ELT processes to dimensional modeling, data warehousing, and impactful visualizations. With a knack for simplifying intricate systems, I build reliable data pipelines, automate reporting workflows, and craft intuitive dashboards that empower timely, data-driven decisions. My goal? To make data accessible, efficient, and powerful for your business and stakeholders.
