Principal Database Reliability Engineer
Oracle • PostgreSQL • MySQL • SQL Server • High Availability • Disaster Recovery • Performance • Automation
Your business depends on databases. You may not need a full-time DBA — but you need experienced database expertise when it matters.
I provide senior-level database administration and Database Reliability Engineering for companies that need reliable, secure and high-performing database platforms.
With more than 20 years of experience in enterprise database environments, I help organizations with Oracle, PostgreSQL, MySQL and Microsoft SQL Server, from everyday operations to complex production incidents and architecture changes.
I can support your internal IT team or take responsibility for selected database environments through a flexible external DBA engagement.
Typical areas include:
Database Administration & Health Checks
Regular database monitoring, configuration reviews, capacity planning and preventive maintenance.
High Availability & Disaster Recovery
Oracle RAC and Data Guard, PostgreSQL replication and Patroni, backup strategies, recovery testing and resilient database architectures.
Performance & Troubleshooting
SQL performance analysis, database tuning, bottleneck identification and resolution of complex production incidents.
Backup & Recovery
Verification that backups are not only running — but that your databases can actually be recovered when needed.
Database Automation
Automation of repetitive DBA operations using Ansible, scripting and modern infrastructure practices.
Migrations & Upgrades
Database migrations, upgrades and modernization of legacy database environments.
Many companies need senior database expertise only several hours per month.
A flexible DBA engagement gives you access to an experienced database specialist who already knows your environment — without the cost of another full-time employee.
The greatest advantage appears when something unexpected happens.
Instead of searching for a database expert during an outage, you already have someone who understands your architecture, backups, replication, applications and operational history.
Stable databases. Faster recovery. Fewer surprises.
More than 200 satisfied clients and years of hands-on experience with business-critical database environments.

Architecture reviews, technology selection, capacity planning and design of reliable database platforms.

HA/DR strategy, replication, clustering, backup architecture and recovery planning.
