At Direct Transact, I develop and maintain cloud-native backend services in Microsoft Azure for a financial services platform. I work with system architects on scalable infrastructure designed to support 99.9% uptime.
I apply Azure security practices and resource monitoring to optimize operating costs and system performance. I also translate stakeholder requirements into technical solutions and contribute to Scrum planning and peer code reviews.
At Online Intelligence (Pty) Ltd, I built and maintained ETL pipelines for high-volume data migration and managed production relational databases. I resolved latency on a core table of 30,142,207 rows through indexing and query tuning, and developed data-processing scripts in JavaScript and C#/.NET for internal reporting tools.
On my database performance project, I implemented a B-Tree indexing plan that cut disk I/O and improved query response times by 40%. I also built a JavaScript utility that monitored ETL processes and alerted engineers to failures in real time.
