Sebastian Hähnel

I am a Senior Software Architect and the CTO/Co-Founder of CatnClever, an award-winning EdTech platform. With over 20 years of experience - ranging from major financial institutions to lean startups - I specialize in building high-performance web architectures and optimizing observability and reliability. As a solo indie builder, I also run pausengames.com, where I treat browser gaming as a playground for product development. I enjoy sharing technical insights on how to build fast, user-centric web products without a massive team.
