If you see a feature that you like in one website, try to replicate it and improve it.
Also, try to create small, regular websites like people request often: photo galleries, e-commerce, blog... since you're a programmer, focuse on functionality more than aesthetics.
Measure the times with different functions and try to improve the SQL queries to gain more speed so you know under which circumstances a query is faster or the connection to the database can be improved
