Hi, I'm Jakub.
Senior Java Backend Developer based in Czech Republic. I build stable, scalable systems for enterprise and financial sectors.
The Journey
It all started at SPŠE IT, where I laid the groundwork for my engineering mindset. I don't just write code; I engineer solutions that last.
For years, I honed my craft at IBA CZ and Hartmann Rico, navigating the complexities of large-scale corporate environments. These experiences taught me the value of rigor, process, and reliability.
In the middle of 2025, I transitioned to freelancing. Now, I bring that same enterprise-grade stability to my clients directly. I believe in proven tools—Java, Spring, and SQL are my weapons of choice because they work, and they scale.
When I'm not coding
I'm still tinkering with technology. You'll find me building hardware projects with Raspberry Pi or experimenting with training custom AI models.
Languages
Communication is key to successful delivery.
