Who am I?

I'm Szymon – a technology enthusiast and software developer. I specialize in building modern web applications – from concept through design to a finished product.

As a freelancer I help companies and startups establish their online presence: business cards, e-commerce stores, web systems and mobile apps. I care about clean code, solid architecture and polished interfaces.

Beyond code I'm interested in electronics, automation and open-source projects. I'm always looking for new challenges that let me grow.
