Senior🎓
Top SchoolJaroslav Hranička is an experienced e-commerce backend developer with 11 years of hands-on experience building and maintaining PHP, Go, and Node.js systems, currently driving backend work at Dr.Max Pharmacy Chain. He favors pragmatic, performance-oriented engineering: improving legacy platforms incrementally rather than rebuilding them from scratch, and leverages microservices where they genuinely add value. His background spans lead and senior roles at Česká televize and commercial e-commerce firms, giving him deep familiarity with high-traffic, production-critical systems. As a long-time self-employed developer he blends client-facing agility with enterprise engineering discipline, often balancing quick wins and sustainable architecture. Based in Prague, he pairs formal CS training (including CS50) with a practical mindset that prioritizes measurable performance gains. Colleagues describe him as unafraid to tackle messy legacy code and focused on shipping reliable, efficient systems.
