From the embedded SQLite to enterprise-level Oracle deployments, I've worked with them all, integrated into software solutions, designed schemas for and tuned existing queries. The latter sometimes by re-writing queries dynamically in SQLAlchemy syntax trees to work around bugs in the target database query optimiser (I'm looking at you, Oracle!). I can work with any of the modern popular databases. If you have older products, I probably can work with them too, I've worked with Informix, Sybase, mSQL and many more.
