Hi! I’m Oracle APEX developer, living in Poland, Warsaw.

If you are not afraid of using plug-ins for Oracle Application Express you might already know me for my multiple contributions to worldwide APEX community

My journey with Oracle APEX started in Pretius company in 2012 where I was developing applications using Oracle APEX 3. When Pretius clients upgraded to version 4.1 I have started building plug-ins to fulfill the need for more complex functionalities which weren’t available as native APEX components.

Most of my plugins were created on behalf of Pretius and are available to the community for free at – learn more about it in My contribution page.


Since 2017 I have stared giving lectures about Oracle APEX plugins at APEX conferences such as ODTUG KSCOPE, APEX Connect, APEX Alpe Adria and POUG.

Through this time I have been honored with title Member of the month at (December 2016 and April 2019). In 2019 I won APEX Competition at APEX Connect 2019 with my plugin APEX Enhanced LOV item.

After APEX Alpe Adria 2019 coreference I had the opportunity to participate (along with my colleague Przemysław Staniszewski) in Juergen Schuster podcast called The Oracle APEX talkshow. If you want to learn more go to and listen to podcast called “Second Line of Defense: Przemysław Staniszewski & Bartosz Ostrowski”.

My plugins are used around the world and most known is Pretius Nested Reports. I’m receiving a lot of feedback and questions regarding advanced usage of my plugins. Because of that, I have decided to start blogging so I can share the knowledge with everyone who is interested in enhancing Oracle APEX.

I hope that thanks to my blog posts you will learn how powerful plugins are and it will convince you to use them in your applications.


In my private time I do climbing, roller blades, yachting, skiing and kite surfing.
