Back to original languageAbout Timm
Do you need a website or digital solution you can rely on – not just beautiful, but also secure, reliable, and easily expandable? That's exactly what I can help you with.
As a web developer with a background in IT security, I build websites, online presences, and custom software solutions for small and medium-sized businesses – from website migration and GDPR-compliant implementation (cookie consent, SPF/DKIM/DMARC email configuration) to custom web applications.
What Sets Me Apart
Most web developers stop at "it works and looks good." With my B.Sc. in IT Security, I bring a keen eye for detail that goes beyond mere functionality: I also ensure that your website or application is protected against attacks – an issue often overlooked by small businesses until it's too late. Multilingualism (DE + EN) and dark/light mode are also part of my standard repertoire.
Typical Projects
Websites & Landing Pages (React/Next.js)
Domain, Hosting & Mail Infrastructure (Migration, DNS, SSL)
Custom Web Applications (FastAPI, Python)
Security Checks & Hardening of Existing Systems - Or if you have an idea for a project but haven't found anyone to implement it cleanly yet.
I work personally, uncomplicatedly, and directly – no anonymous agency ticket system, but a dedicated contact person from the initial idea to go-live.
