About Ceki Gulcu
Ceki Gulcu is a Swiss software engineer of Turkish origin and the founder of the popular log4j, logback and SLF4J projects. Ceki is a graduate of the Swiss Federal Institute of Technology in Lausanne. He worked at the cryptography research group at the IBM Zurich Research Laboratory where Ceki and Prof. Gene Tsudik developed a bi-directional anonymous email system called “Babel” which indirectly paved the way for the Tor anonymity network. While at IBM Zurich Lab, Ceki authored a logging framework which, after some meandering, eventually became log4j 1.x. Late 1999, log4j was donated by invitation to the Apache Software Foundation where Ceki served as a VP for Apache Logging Services from 2000 to 2005. In 2006, Ceki founded the SLF4J and logback projects and continues to maintain them until this day. Cumulatively, the artifacts of these two projects are downloaded over 4 billion times per year. Given their popularity, maintaining SLF4J and logback is a recurrent and time consuming task. In 2022, Ceki started the reload4j project with the goal of fixing critical security issues in log4j 1.x. He is unaffiliated with log4j 2.x.
