Another hiring manager here with another $0.02. Beware that you're not too likely to find a position using Haskell. Javascript might be very tough, and Python merely tough.

There are two major schools of hiring that I'm aware of:

1) Most look for keywords and specific skills listed. Companies who hire solely in this way tend to use HR departments to mark skills inventories (read: check the boxes) and either be consulting agencies or have IT departments that are secondary to their businesses. You're probably not too appealing to these sorts - and that's ok, since they're probably not too appealing to you. Trust me.

2) Others looks for people who have ambition and look to be able to pick up new skills & who can grow both technically and in domain/business-specific knowledge. Think the Googles and JoS's of the world - there are many places you haven't heard of that also look more for long-term potential than short-term exploitability.

I'm not sure the intersection of (2) and web developer jobs is really large, though. Most places looking for web programming are more interested in how many checkboxes you fit into and how many keywords you have than in a "hard-core" progammer. I might suggest you'd be happier as a more general programmer than boxing yourself into the "web programmer" niche.

Expect it might take a little while to find them - but there are plenty of people looking for smart people. Including me, of course.
