I learned my first programming language at six on an Apple ][ and sold my first commercial application at sixteen. I though myself C including pointers when I was a teenager by reading the K&R book. These days I code mostly in Javascript, Swift, Java and some Python but in the past I have written programs in Assembler, all C flavors including Objective-C, Scheme, Perl, bash and PL/SQL among others. In short, I have been around the block and I can help you understand and share insights that only many years of experience bring.
