I would like to know if there are some jobs you can mostly work from home. I live in small country (Croatia) and bioinformatics jobs are very rare. I would like to find a bioinformatics freelance job and I don't know what kind of job to look for or what education do I need. I have a degree in biotechnology and I worked as a volunteer in one bioinformatics laboratory during my faculty where I gathered and analysed data. I started learning Python a while ago to improve my knowleedge. I would appreciate any answer! Thank you very much!
One area you might consider is curation. There is a huge need for people who understand the biology, aren't afraid of a bit of computation--but not all jobs require heavy coding--and can talk to people who do the software side.
There's an international organization of curators that might offer some other guidance: http://www.biocurator.org/home.shtml
I have known a number of curators who worked from home. That said, it might require you to structure yourself into a little company of some sort to make getting contracts easier. I don't know how that works outside of the US.
Some people won't consider that bioinformatics per se, but you will be associated with bioinformatics groups and programs with this kind of work.
Another option is to participate to an open source project like The Synaptic Leap, part of the Tropicaldisease project, which aims at creating an online community to ultimately find a cure for many neglected diseases.
In January/February you can start looking at the application calls for the Google Summer of Code projects; see this question for hints.
The other answers, working as a curator or to consulting, are very good idea.
In any case, unfortunately the skill needed for entering in this field may be a big too high. You should consider going abroad to make some experience in a laboratory of bioinformatics.
There is the Mechanical Turk of Amazon http://www.mturk.com. I have experienced a bit with this platform, both as a requestor and worker. The revenue's are though small. I am not sure if you can make a living on mturk. But looking at the quality of results I received as a requestor, people apparently do. It would be nice to have more bioinformaticians on the workers side. Mturk does have the disadvantage that it is mainly oriented on the US. As a non us citizen, you get paid in Amazon vouchers.
Another option might be http://www.vworker.com, but I haven't tried that yet. It used to be known as rentacoder, but recently changed its name to cover a broader audience. Testing it is on my to do list.
Another Open Source project similar to The Synaptic Project is OSDD. Open Source Drug Discovery(OSDD) is a project initiated by CSIR,India for discovering new drugs for TB. There are interesting projects that involve data mining, virtual screening of drugs, annotation and curation.
