Sia Shamsai
Principal SQL Server DBA & Founder
Over the past 25 years, Sia has worked with enterprises including Dominos, QSuper, Qantas, Navman, and Super Retail Group to ensure their SQL infrastructures are correctly designed, configured, monitored, performance tuned and maintained using industry best practice methodologies.
His expertise spans infrastructure architecture, disaster recovery solutions optimised for RTO/RPO requirements, and SQL Server performance tuning, with a recent focus on AI-enhanced analytics and business intelligence systems.
Sia established DBA Services to provide businesses of any size or SQL Server complexity with a cost-effective solution for accessing the same specialist SQL Server skillset and technologies as used by some of Australia's largest SQL infrastructures - consumed as a service, so that the business only ever pays for the support they actually require.
While headquartered in Brisbane, DBA Services serves clients across Australia, New Zealand, the UK, Europe, and Asia.
Enterprise expertise across every sector
We've worked with some of Australia's largest SQL Server infrastructures - including Dominos, QSuper, Qantas, Navman, Teachers Health Insurance, WorldLine, and Super Retail Group - across finance, superannuation, eCommerce, recruitment, healthcare, government, and more.
How we're different
Enterprise-Grade, AI-Enhanced
Agentless monitoring leveraging native SQL Server capabilities, enhanced by AI-powered telemetry analysis. We detect anomalies in wait stats, performance counters, and query patterns - while never touching your business data.
No Lock-in, Full Transparency
Month-by-month support from as little as 2 hours per month. 15-minute billing increments with comprehensive work summaries. You stay because the service is valuable, not because you're locked in.
Full Ownership
We take complete responsibility for the SQL Server instances under our management. Proactive monitoring, regular reviews, and on-call support - your SQL Servers are our priority.
