About Me

Lukas Jelinek
15+Years
Experience

As a CEO and Full-Stack Engineer, I combine deep technical experience with a product-focused mindset.

I started as a software developer, building scalable systems and practical tools. Over time, I've expanded into broader responsibilities — founding teams, managing operations, and shaping products — while continuing to stay hands-on with code.

I love building things that solve real problems. Whether it's scaling systems, refining products, or helping a team deliver — I stay close to the code and focused on making things work. My work lives at the intersection of engineering, product, and business — always grounded in execution and results.
