Database Administration
PostgreSQL, Oracle, MySQL and SQL Server environments installed, upgraded, patched and maintained in production.
High Availability & Clustering
Highly available PostgreSQL clusters built on Patroni, etcd and HAProxy, with connection pooling and service discovery behind them.
Replication & Disaster Recovery
Streaming replication and Oracle Data Guard, with switchover and failback rehearsed in a live banking environment.
Performance Tuning
Assessment and tuning at operating system, query and database level, supported by centralised performance monitoring.
Backup, Recovery & PITR
Backup strategy, restoration, point-in-time recovery, WAL archiving and Data Pump operations — tested rather than assumed.
Data Security
Security policies, user management and data masking applied so that access to production data stays deliberate.
Technical Documentation
Procedures, health-check scripts and reference material written so another practitioner can follow them unaided.
In Practice
Systems, in production.
