Christoph Schiessl

Hi, I'm Christoph Schiessl.

I help you build robust and fast web applications.


I'm available for hire as a freelance web developer, so you can take advantage of the more than a decade of experience I have collected working on many projects across several industries. Most of my clients are building web-based SaaS applications in a B2B context and depend on my expertise in various capacities.

More often than not, my involvement includes hands-on development work using technologies like Python, JavaScript, and PostgreSQL. Furthermore, if you already have an established team, I can support you as a technical product manager with a passion for simplifying complex processes. Lastly, I'm also a skilled writer who takes pride in breaking down technical concepts into the simplest possible terms.
