A bioinformatics database backend
The project involved porting the backend of an existing R+Perl+Sh+PHP based bioinformatics site to a Java based web application allowing easy generation of an operational database from several hundred megabytes of raw data from public bio databases, as well as an UI for curating the database contents.
