Free Consultation!

I offer free consultations on database issues related to Database Architecture Design and Incident Resolution. Whether you need a truly professional DBA to review your costly vendor's database architecture design or assistance with an urgent case where you feel stuck, I'm here to help.

*Hand-on service is not included in Consultation. In case of dispute, the decision of mine shall be final and conclusive.

Why Me

As an experienced database administrator with a background in both vendor and in-house companies, I have observed that many companies face challenges with their database systems. For example, flawed architecture fails to protect your important data during disasters. On the contrary, overly complex architecture leads to high costs and difficulties for maintaince and operation.

Believe Me. I know your situation.

Finding a DBA who is not only "Vendor Manager" can be challenging. Often, companies resort to consulting with large IT vendors, which can be costly. After several months, you might hear that the best dba from your vendor has resigned, leaving you with uncertainty. To compound matters, when your primary server farm goes down, you might only be able to recover data from five hours ago on the standby server, despite investing heavily in an architecture that promises 99.99% availability.

Believe Me. I know your feeling.

Having worked as an engineer at one of the world's leading IT companies and as an in-house database administrator in both banking and academic, I offer expert support for a variety of database systems, including Oracle, MySQL, SQL Server, and PostgreSQL. My expertise extends beyond basic installation to designing architectures that truly meet your business needs while maintaining budgetary constraints. Additionally, my designs prioritize ease of future maintenance and operations, including patching, upgradation, failover, and restoration.

Believe Me. I know your concern.
