What I'm looking for

I am looking for a role that challenges my skills and offers opportunities for growth in a collaborative environment.

I am a dynamic Oracle Database Developer with over 16 years of experience in database design, optimization, and PL/SQL programming. My career has been marked by a proven track record of enhancing performance, including a 65% gain in application performance through strategic partitioning and a 31% boost in overall functionality by refactoring poor-performing queries. I am adept at mentoring teammates and creating detailed reports that guide strategic decisions.

In my most recent role as a Senior Oracle Developer at Infosys, I completely redesigned and optimized stored procedures, achieving a 31% enhancement in performance. I engineered a partitioning strategy on key database tables, resulting in a 65% performance gain. My commitment to excellence has been recognized with the Infosys Spot Award for exemplary database design and development. I thrive in collaborative environments, where I can leverage my expertise to drive database improvements and deliver high-performance solutions.
