Looking for a jobDataOps Engineer (BI Analytics & Automation)
Data Engineer at betXchange building API-to-reporting workflows and automated data integrations.
South AfricaDataOps Engineer (BI Analytics & Automation) at betXchange
About
At betXchange, I develop and support scheduled ingestion workflows that connect REST APIs, relational databases, files, SharePoint and Power BI Service for operational reporting. I implement pagination, date-window parameters and validation to make API-fed datasets more consistent.
I also build and troubleshoot Power Query transformations and Power BI semantic models, including incremental refresh filters and fact/dimension relationships. I diagnose refresh and connectivity issues, and support authentication and proxy integrations using Cloudflare Workers and Power Automate.
On the FICA verification integration, I supported automated identity-verification flows and contributed to transition planning from scheduled flows to a containerized service. I also developed an academic document-request application in C# and ASP.NET Web Forms during my internship at University of Johannesburg (YES4Youth).
