I started working with Java in late 1997 (JDK 1.1) during my university studies. My first serious project was in 1998 when I created an image processing application using vectorial quantum algorithms as my diploma project - an early adoption of Java technology in academic research.


Throughout 27+ years, I have evolved from developer to senior developer, team leader, and now Platform Architect. I've been actively involved in diverse projects across multiple teams, designing and implementing libraries and applications that power enterprise systems worldwide.


Since 2011, I've been giving back to the software community through open source contributions. My GitHub projects have connected me with skilled developers who share my passion for software excellence. This journey led to creating PF4J, which now powers plugin extensibility for Netflix's Spinnaker platform, Facebook's Buck build system (Java version), Huawei Cloud's real-time data processing systems, and Eclipse Foundation's automotive software platform.


Today I work independently as a platform architect and founder. I built BVB Analytics, a financial data platform for the Bucharest Stock Exchange with ESEF/XBRL parsing pipeline, multi-model valuation, and AI investment thesis for 55+ listed companies. Previously at Itiviti (Broadridge), I worked on Global Data Management architecture for their award-winning trading platform serving 24 of the top 25 global investment banks.


Today's Java ecosystem represents much more than a programming language - it's a mature, constantly evolving platform with fascinating components. My experience spans from JDK 1.0 to Java 21, and I continue to work with the same passion I had at the beginning.


Long live Java!
