What I'm looking for

I seek senior roles leading cloud database migrations, HA/DR and performance tuning within secure, compliance-focused teams that value automation, mentorship, and measurable scalability improvements.

I am a Microsoft Certified Azure Database Administrator with over 17 years of IT experience, including 8+ years specializing in SQL Server and PostgreSQL environments. I lead database architecture, cloud migrations, and performance tuning for banking, fintech, ERP, and data warehousing systems.

I have delivered high-availability solutions (AlwaysOn), automated maintenance and CI/CD integrations, and significant query performance improvements—often reducing runtimes by over 60%. I mentor DB teams, conduct SQL code reviews, and enforce compliance with GDPR and HIPAA.

I design and execute large-scale migrations to Azure and AWS, implement encryption and row-level security, and streamline ETL/ELT pipelines with SSIS and Azure Data Factory to ensure scalable, secure, and compliant data platforms.
