Leon T. Magara
SQL + Power BI specialist. I turn messy data into executive-ready insights.
Five years of production SQL across SQL Server, PostgreSQL, MySQL, and Snowflake. Remote-first with US, European, and African clients. Currently building full-stack business systems for emerging market SMEs at InterConsult Zimbabwe.
Most data problems aren't dashboard problems. They're pipeline problems. The data is messy, the structure doesn't exist, the reports don't connect to decisions, and nobody owns the full picture.
I do.
Every project below represents a stage of the data lifecycle I've built for real clients — from raw cleanup to production-grade systems. Together, they're proof that I don't just build dashboards. I solve the whole problem.
Chaos to clarity. Every stage.
