♦ contribution and further development of the Apache UIMA Cas Editor♦ refactored the API and code base to use Java 5 Generics♦ PMC member after graduation from the Apache Incubator♦ managed and integrated several contributions into the UIMA codebase♦ reported and helped to fix numerous bugs in UIMA-AS

♦ joined the project by contributing the OpenNLP UIMA Integration and API extensions for it♦ many contributions that enabled easy training, evaluation and running of OpenNLP components♦ contributed the majority of the tests and developed a test plan to maintain a high level of quality♦ introduced and documented the release process♦ wrote most of the OpenNLP documentation in order to lower the entry barrier for new users♦ helped out with countless tasks that turned OpenNLP into a successful Apache project♦ used OpenNLP since 2005 at my day jobs♦ introduced the formats package and added native support for a selection of publicly available corpora

♦ Build the data pipelines for the new Maritime 2.0 product for tracking vessels based on Apache Flink (doing stream and batch processing), NoSQL for storage, Kafka. And gained a lot of experience with AIS. Product page: https://spire.com/maritime/♦ Build the data pipeline for the Airsafe product for tracking aircrafts with Apache Flink (doing stream and batch processing), NoSQL for storage, Kafka, ElasticSearch. Learnt a lot of ADS-B. Product page: https://spire.com/aviation/♦ Worked with AWS, Terraform, CI/CD pipelines.♦ Gained operations experience and performed on-call duties

♦ design and implementation of kyc3.com a big data open source intelligence (OSINT) system for combining and analyzing an enormous amount of (semi) structured and text based data♦ design and implementation of TRIX a travel risk assessment system for a private jet operator♦ Big Data (Flink, HBase), Natural Language Processing♦ Deep Learning for NLP with Apache MxNet, DL4J and Tensorflow

♦ built a prospective search system with UIMA, dtSearch and Lucene♦ worked with Solr in a big data document storage prototype♦ explored possibilities to use Apache OpenNLP and UIMA for media monitoring and analysis♦ provided expertise to replace a propertitary search engine (dtSearch) with Apache Lucene♦ designed and partly implemented a Hadoop and UIMA-AS based storage and text anaylsis system♦ part of the research department to explore new possibilities to optimize costly processes♦ developed a parapharsing prototype with Moses in C++♦ implemented a news article summerization prototype♦ built a topic detection and tracking prototype♦ Big Data, Natural Language Processing, Search

♦ investigated how information from clinical notes could be extracted for a data mining project♦ built a prototype with IBM OmniFind and IBM UIMA NLP pipelines to index clinical notes♦ developed an Eclipse and UIMA based annotation tool (now Apache UIMA Cas Editor)♦ developed a UIMA integration for OpenNLP, now part of the Apache OpenNLP♦ customized the OpenNLP NameFinder feature generation to improve performance on clinical documents♦ built a statistical information extraction system♦ implemented a system to predict missing values in time serieses captured during dialysis with linear regression (Bachelor thesis)

♦ desgined and implemented a web based remote adminstration and screen sharing solution for a dialysis machine (FMC SleepSafe) with a touch screen♦ as part of this project I implemented a custom protocol stack to communicate with the machine and a screen rendering engine♦ embedded device development♦ integrated a USB card reader via JNI, C++ and Java into a clinical management system
