WEB DESIGN · WEB DEVELOPMENT · E-COMMERCE
Websites that do more than look good.
I plan, design and build custom websites and online shops for companies, brands and sports organizations.
My standard: clear structures, thoughtful design and a technical build that fits each project.

SELECTED WORK
Selected projects.
Every project has different requirements. What matters is turning them into a digital solution that makes content easy to understand, fits the brand and works in everyday use.
ASSOCIATION · WEB DEVELOPMENT
Tennis Association Berlin-Brandenburg
Complex information. A clear digital presence.
For the Tennis Association Berlin-Brandenburg, I planned, designed and built the new web presence.
The particular challenge was to make a large amount of information clearly accessible to different audiences.
The focus was therefore on a rethought information architecture, clear navigation and a unified visual concept.
Thanks to my own background in competitive tennis, I could bring requirements and user perspectives directly into the development.

BRAND · E-COMMERCE
Close Call Clothing
E-commerce meets brand identity.
For Close Call Clothing, I built an online shop that brings together products, brand identity and storytelling.
As a co-founder, I know not only the design and technical requirements but also the business perspective behind a digital business model.
The goal was a consistent brand world in which product presentation, design and shopping experience work together.

WHAT I DO
From the first idea to the finished website.
I support digital projects from concept through design to technical implementation. Depending on the requirements, the result is a complete new web presence or the targeted further development of an existing solution.
Websites & Relaunch
Custom websites for companies, organizations and brands. Whether it is a new web presence or a comprehensive relaunch: the focus is on a clear structure, a suitable design and reliable technical implementation.
E-Commerce
Online shops that present products convincingly and make buying easy. I think about brand presence, product presentation, user guidance and technical implementation together.
Development & Support
A website is not finished at launch. I help with the further development of existing websites, the implementation of additional features and, if you wish, ongoing technical support.
PROCESS
A clear process. From start to launch.
Good digital solutions come from a clear understanding of the requirements and a structured collaboration. I guide projects personally and handle both the design and the technical implementation.

ABOUT MY APPROACH
Technical understanding meets a business perspective.
I am Jonas Pelle Hartenstein, a professional tennis player, entrepreneur and web developer.
Alongside my sports career, I have built my own companies and planned and delivered a variety of digital projects.
These experiences shape my work: I look at websites not only from a design or technical point of view, but also think about what role they should play for a company or an organization.
From the first idea to launch, I guide projects personally and take care of both the design and the technical implementation.

Frequently asked questions.
How much does a website cost?
The cost depends on scope, features and individual requirements. After an initial conversation, I can estimate the effort and prepare a concrete quote.
Can an existing website be reworked?
Yes. Depending on the technical foundation and requirements, an existing website can be optimized in a targeted way or rebuilt completely.
Can I edit content myself later?
If this is part of the project, I use a suitable content management system so you can maintain content on your own afterwards.
Do you also provide support after launch?
If you wish, I also help after publication with technical questions, adjustments and further development.
