my name is Nikolay Savvinov and I am an Oracle engineer. I have been working with Oracle since 2006. In 2007 I got my OCP certificate. I mostly specialize in performance troubleshooting, both on statement and instance level.
I provide free tuning help to beginners (see “Ask me” page). I am also available for hire (preferably for part-time remote work, but all reasonable offers will be considered) — if you’re a potential employer, email me at nsavvinv “at” gmail “dot” com and I will get back to you.
