What I'm looking for

I’m looking to move further into database reliability, particularly high availability, replication and disaster recovery at scale, building on the backup automation and incident response already running in production. I’m open to relocation to Canada or fully remote work across UK, EU or UAE time zones; visa sponsorship or employer-of-record is welcome.

At N3O Ltd, I run 30+ self-managed PostgreSQL instances on Kubernetes for a multi-tenant SaaS platform. I root-caused a pgBackRest parallelism bug that was failing backups, tuned backup processes to pod sizes, and fixed a CI pipeline bug that stopped tenant database pods from starting.

I’ve also built ASP.NET Core microservices for donor and donation processing, handling over 1M transactions a day, and set up event-driven notifications with Azure Service Bus. I’m looking to move further into database reliability, building on my production experience with backups and incident response.
