Description

Does your environment have performance issues, blocking, deadlocks, or high response times? Do you need to validate that your high availability, backup, or disaster recovery strategy will actually work when you need it?

I help organizations diagnose, optimize, and secure Microsoft SQL Server platforms both On-Premise and Azure, identifying risks, eliminating bottlenecks, and improving the availability, security, and performance of their data systems.

My experience focuses on mission-critical enterprise environments where business continuity, operational stability, and information protection are key factors.

I can help you with projects such as:

✔ Advanced SQL Server performance diagnostics and optimization.

✔ Analysis of blocking, deadlocks, and concurrency issues.

✔ Query, index, and execution plan optimization.

✔ Technical audits of SQL Server and Azure SQL.

✔ Review of On-Premise, IaaS, PaaS, and hybrid architectures.

✔ Evaluation and improvement of Always On Availability Groups and Failover Clustering environments.

✔ Business continuity, high availability, and disaster recovery (DRP) strategies.

✔ Security audits, access control, and privileged account reviews.

✔ Implementation and validation of encryption using Transparent Data Encryption (TDE).

✔ Review of backup, restore, and recoverability testing strategies.

✔ Protection of sensitive information through data masking and obfuscation techniques.

I currently work administering and optimizing enterprise SQL Server platforms for large organizations, combining expertise in databases, infrastructure, and Microsoft data platforms.

I also offer expertise in SSIS, SSRS, SSAS, Pbi, DW, BI, and Python, and integration of analytical solutions, allowing me to analyze the entire data ecosystem when the problem involves more than just the database itself.
