Hi there, I'm Jan 👋

Senior Full-Stack Engineer | Bootstrapper of Triathlon Pace

I specialize in architecting high-performance, enterprise-grade web applications using Angular 21 and Node.js. With a strong focus on Server-Side Rendering (SSR), SEO optimization, and scalable systems, I help teams and businesses build software that is fast, resilient, and maintainable.

💼 What I Do

  • 🏗️ Architect & Build: I design State-of-the-Art (SOTA) Angular architectures. Check out my Angular 21 Reference Architecture for a masterclass in modern frontend structure.
  • 🚀 Performance Optimization: I specialize in Core Web Vitals, intelligent asset preloading, and custom SSR/SSG request flows.
  • 🛠️ Solo Bootstrapper: As the creator of Triathlon Pace, I handle everything from database design and robust Node.js APIs to highly interactive Angular UIs.
  • 🤝 Freelance & Consulting: I am currently available for freelance contracts. If you need a Senior Angular Engineer to rescue a legacy codebase, boost performance, or build an application right the first time, let's talk.

🛠️ Technology Stack

  • Frontend: Angular (v17 - 21), PrimeNG, PrimeFlex, RxJS, Signals
  • Backend: Node.js, Express, TypeScript
  • DevOps: GitHub Actions, Docker, Cloudflare, Server-Side Rendering (SSR)
