Ask HN: Dev bootcamps for experienced but mediocre developers

Are there any Dev bootcamps targeted at experienced developers?

I'm talking about your average Joe working in the corporate world who knows how to mashup frameworks together and get a working product but lacks a solid grasp of the fundamentals. Things like: Algorithms & DS, Operating Systems, Concurrency, Functional Programming, software design and design patterns, problem solving skills, open source tools and contributing to open source projects, etc.

Basically the skills your average corporate programmer needs to join companies like Google, Amazon, etc.
