Building blazing fast apps with Python and Svelte

  • Cybersec
  • Fintech

Mixing science with hands-on experience

Intro

I work primarily with two technologies: Python and Svelte. I combine them to build applications that are not only lightning-fast but also easy to maintain in the long run. This very site is an example of that approach: static content, no unnecessary server infrastructure, and fast loading across all browsers. I gained most of my experience in fintech, developing applications for financial institutions, while also exploring cybersecurity and artificial intelligence along the way. Rather than chasing every new trend, I make deliberate technology choices—clean architecture, testing, and avoiding technical debt matter more to me than a trendy stack. Below, you’ll find descriptions of my projects and blog posts where I dive into the technical details.
