What I'm looking for

I seek roles focused on database development and migrations where I can apply PL/SQL and cloud data platform expertise, collaborate with stakeholders, and solve complex data challenges.

I am an experienced Oracle PL/SQL developer with a long track record delivering database solutions, migrations, and AMS support across telecom, retail, and utilities sectors. I specialize in translating business requirements into reliable, performant database logic and automation.

I have led and contributed to multiple migration projects moving code and data between platforms, including Teradata-to-Snowflake on Azure, Oracle-to-SQL Server anonymization work, and cloud migration efforts. I routinely perform code reviews, performance tuning, and integration testing to ensure quality deliveries.

My background includes building backend database designs, complex PL/SQL packages, procedures, and job scheduling on Unix/Linux. I have also provided AMS, solution design, and support while collaborating closely with clients and stakeholders to align technical solutions with business needs.

I bring strong analytical skills, attention to detail, and a cooperative team approach, having taught database and development topics earlier in my career and mentored peers during projects to ensure timely, defect-minimized releases.
