What I'm looking for

I'm looking for an immediate-start data role where I can build reliable pipelines, improve data quality, and turn analysis into clear business recommendations. I'm open to hybrid and remote arrangements.

I've built end-to-end data projects spanning production-grade ELT pipelines and executive data storytelling, including a cloud-native weather pipeline on AWS S3 and Apache Airflow and a production e-commerce pipeline with validation, quarantine, logging, alerting, and pytest coverage.

In my current data support work at Motivity South Africa, I troubleshoot systems and infrastructure issues, escalate data integrity concerns, and document recurring processes for cross-functional teams. Through freelance web and data development engagements, I've translated stakeholder requirements into technical solutions and delivered system documentation for non-technical audiences.

My portfolio analysis has quantified revenue risk, partner-performance trends, and recovery opportunities using Python, SQL, Pandas, Matplotlib, DuckDB, dbt, and Google Looker Studio. I enjoy turning raw data into reliable infrastructure, clear findings, and prioritized recommendations that support business decisions.
