Background

About Daniel Sladecek

I’m a Frontend Developer with 8+ years of experience building scalable, user-focused web applications. Skilled in JavaScript, TypeScript, React, Vue, and modern frontend tooling, I specialize in creating clean, maintainable codebases and intuitive interfaces. For the last 6+ years at Gen, I’ve been part of the team behind the Checkout application, a high-traffic e-commerce platform serving millions of users. My work has focused on performance optimization, accessibility, and delivering reliable user experiences at scale. I’m comfortable working with AI-assisted development tools (such as GitHub Copilot and Claude Code) as part of my daily workflow, using them to accelerate iteration, explore solutions, and improve code quality while keeping engineering judgment and system design firmly human-led. What I bring: • Strong expertise in modern JavaScript ecosystems (React, Vue, TypeScript). • Proven track record on large-scale consumer platforms. • Experience balancing new feature delivery with legacy system maintenance. • Collaborative mindset, used to working in agile, cross-functional teams.
