Sorry, sounds a bit like you're copping an attitude here. There's a lot more to software developement than any one or two things (scaling issues? complex infrastructures?). Don't be complacent and think because you've done X, you know all about Y and Z. I once worked with a guy who started with a company at age 16, did a lot of stuff, wrote a lot of code (went to work for amazon after that actually). Turned out a lot of the things he did, although valuable in the moment to make the sale, were terrible for the long term viability of the product. This kids unguided decisions literally set the company back years when growth took off, and the app couldn't scale, and security holes were gaping.

Just be wary of thinking you know it all, this applies to everyone, regardless of age or experience.
