About Ilija

I am Ilija Scheuermann, a self-employed fullstack web developer under the brand Intelisign, with a focus on e-commerce frontends. Since September 2025, I have been working continuously for Handelskontor 24/BadDepot: from the initial project phase in the family business, through permanent employment, to today's independent collaboration under Intelisign.

My focus is on the performant connection of frontend and backend (PHP, Smarty, JavaScript, HTML5, CSS3) to directly increase the usability and conversion rate of shop systems. This also includes the integration of AI tools into the daily development workflow, from audit scripts to custom browser extensions.

Another project: for the wedding company Stadler Emotions, I developed an individual shopping cart configurator that allows engaged couples to put together their own service package.

From October 2026, alongside my ongoing freelance activities, I will deepen my understanding of secure web architectures with a B.Sc. in Cybersecurity at the Furtwangen University of Applied Sciences.
