jaroslav@hranicka:~$ whoami

Hello, I'm Jaroslav Hranička.

I'm a backend software engineer from Czechia with 15+ years of professional experience. I specialize in building efficient, secure, and highly scalable systems.

My journey spans from small agile startups to enterprise-level architecture. I have engineered solutions for large e-commerce platforms, mission-critical internal services, national television networks, and an international pharmacy chain.

Historically, my expertise was deeply rooted in PHP and the Symfony ecosystem. Nowadays, my primary focus is building high-performance backend systems with Golang.

I'm a firm believer in writing clean, maintainable code and aligning technical solutions with real business needs. My approach is to always prefer simplicity over unnecessary complexity — solving problems with clarity and elegance.

If a service needs some frontend, I pair it with a modern Vue.js interface.
