If you've already built some apps perhaps you can think about what kind of development you are interested in. Do you want build start up applications? Desktop applications? Cool mobile apps? Do you like database SQL or creating cool UIs? These choices probably dictate where you apply, your position and the tech stack that you may want to focus on.
If you like Rails, you might look into aloha.rb and see what kind of Rails opportunities there are on the island.
I also think mobile is pretty hot right now and is here to stay. Android, ios development is in demand.
You could combine your knowledge of biology with your new interest in programming. Does the idea of building applications for genetic and proteomic analysis interest you? The field of bioinformatics, the application of computer science to molecular biology, is exploding. People with a knowledge of biology and programming are very valuable, so you are in a good spot.
If you are interested, the amusingly titled Bioinformatics for Dummies is a good start. I found it very useful when I was working on a drug discovery related app.
Rails is a good choice for web app development. Strong rails developers can find work in Hawaii. .NET positions are frequently posted in the Jobs Forum. As Scott mentioned iOS and Android developers are also in demand.
