I’m a senior database administrator delivering secure, high-availability Oracle, PostgreSQL, and SQL Server platforms.
What I'm looking for
I’m an accomplished Database Administrator with 8+ years of expertise managing and optimizing mission-critical Oracle, PostgreSQL, and Microsoft SQL Server environments. I deliver high-availability, secure, and scalable database solutions across on-premises, cloud (AWS, Azure, Oracle Cloud), and data warehouse (Snowflake) platforms, with a strong focus on operational reliability and measurable performance.
I lead end-to-end DBA work—installations, configuration, upgrades, patch management, performance tuning, and backup and recovery using tools like RMAN and Data Pump—while implementing security hardening aligned to FISMA and NIST 800-53 controls. I’ve engineered high-availability architectures (Oracle RAC, Data Guard, GoldenGate, PostgreSQL Streaming Replication) and modernized systems through cloud migrations and automation with SQL, PL/SQL, PowerShell, and UNIX scripting, earning an active Public Trust Clearance and cybersecurity-focused certifications (including AWS Solutions Architect, Oracle OCP, Security+ and CySA+).
