About
I am a software development professional with hands-on experience in Java/JEE, Spring Boot, REST/SOAP APIs, and modern front-end technologies.

Currently, I am expanding my expertise in Python and computer vision, exploring opportunities to apply machine learning and image processing to real-world problems while continuing to optimize solutions through CI/CD, cloud, and agile practices.
