Schools in this area are below average. Tons of ESL students that close to the border which will tend to bring the numbers down. Based on your lack of knowledge about San Diego I’d recommend renting somewhere at least a year to get a feel for where you might want to be. Most of the IT work is around sorrento valley and rancho bernardo so you’d probably be better off with something a little closer to those job centers, 92126 or 92071 will have stuff in your price range with a shorter commute and better schools.
