Hi,
looking at your project description, I think this is the best suited job for me as I have over 8 years of experience in Database Development along with Performance Tuning. I have worked on various Databases like Oracle, SQL server, PostgreSQL etc. I have done OCA certification in Database Development and Oracle 12c: Performance Tuning and Management certification. Expecting a call from you where we can discuss further and I can prove my knowledge for this job to you.
