About this Gig
I set up, fix and failover-test SQL Server Always On Availability Groups. Lead DBA with 8 years of experience running a large-scale banking estate on geo-distributed Always On AGs across two data centers, Microsoft-certified (DP-300, DP-800).
What I cover: WSFC and quorum design, endpoints and certificates, listeners and read-only routing, synchronous vs asynchronous commit, seeding, and backups on secondaries.
The hard cases: replicas stuck in RESOLVING, redo lag, listener failures, and network or heartbeat problems between sites.
Every engagement ends with a controlled failover test and documentation (written runbook in Premium). Changes to production are scheduled and approved by you. Please message me before ordering so we can confirm your topology.

FAQ
Can you work on my production servers?
Yes, in a maintenance window you approve. I start with a read-only assessment, share the plan, and only then make changes, always with a rollback path and a failover test at the end.
