PostgreSQL is a lovely database management system that can scale with most organization's needs.
If you're finding your application performance degrading overtime, it's possible that your database is no longer setup to meet your needs. Data models change, queries become more complex, indexes go unused-- what worked for a 5-gig database doesn't work for a 20-gig database with hundreds of concurrent users.
I can help get your site's performance back to where you need it to be.
Leverage my experience in postgresql so you and your team can focus on delivering the roadmap.
