Tech: Primarily Java with some C, C++ and more recently Go (although Go is only in our code playground, nothing even close to production yet)
Location: West London
Company: Small but well established (since 1996). There are 4 developers including myself. One software is one part of what we offer.
Edit: I know you said without benefits, etc. but I included it for others as well. Just look at the £85k figure if you want a hard number.
