No matter whether it's a one-pager, a corporate website or an entire portal for your company. With individual solutions, based on proven systems, I design and implement your website precisely, in order to create a great impression.
With focus on modern TypeScript/Javscript I develop your application in the backend in Node.js and in the frontend with React (Native) not only in the web, but also as iOS and Android App. In addition I write classic PHP, HTML5, CSS3 and (ES4) JavaScript or Angular applications.
Applications need to be well-conceived both during development and operation in order to work sustainably, reliably and cost-effectively. With modern design patterns I lay the foundation for a successful project.
Jan Karres, freelance software developer
from Munich, Germany since 2013.
It is my passion to comprehensively understand projects in order to optimally organize them for you from the vision to the deployment. I understand the technology as a fundamental tool, which must be in line with your area of expertise, business objectives and a user-friendly design.
You can book me on a project basis for the conception of projects, the development of web applications preferably in TypeScript/JavaScript or for the creation of your individual website.
“I have been working together with Jan for years and have always felt very comfortable with all questions concerning web development. I am happy to know him and recommend his work every time when it comes to challenging projects that require 100% reliability.”
“Jan created an individually designed website for me and supported me with tips and tricks to make it even more appealing and representative. Thank you for the uncomplicated handling and precise communication!”
“Jan was responsible for the conversion of the club page of the cic! Cyber Investment Club. He proved to be very competent and reliable, always on the spot and always available. The same applies to the blog vorunruhestand.de, which would hardly be as successful without Jan's help.”
I developed the company website of the personnel agency INSIDE management from Frankfurt am Main, Germany as a modern one-pager. The focus was on concise texts an expressive visual design of the offered services and a direct approach to all target groups. Simple, but effective design.
