A still ongoing project in a German bank to replace several MS-Office-made “applications” with sophisticated software.
This project involved a 3-tier setup (web server, application server, database). The code was in a state of “proof of concept”. Complete refactoring needed.
A custom Arabic Lucene analyzer had to be integrated into Elasticsearch. The custom analyzer was written for Apache Lucene.
I contributed to c:geo, THE open source geocaching App for Android which runs on about 1.5 million devices.
