About Jan
With a passion rooted in Oracle technologies, I am behind the oneoracledeveloper.com blog and proudly hold the first and only Oracle ACE title in Czech republic. I boast over 20 years in Oracle PL/SQL & APEX development. With a product owner mindset, I emphasize clean code, agile methodologies, and quality-driven solutions. My expertise spans from database modeling to UI/UX design. Passionate about continuous learning, I offer Oracle courses and services at www.jankvetina.cz and remain committed to elevating software development standards. I am also available for work as a contractor. Don't forget to checkout my GitHub projects including the APEX Deployment Tool.
