Hello, I am Ben Konrath
& I am a software developer

My current focus is freelance full-stack web app development using Python / Django and JavaScript

I'm an experienced software developer with a broad knowledge of web-technologies and the ability to dive into expert-level detail as needed.

High Quality

My focus is on high quality, long lasting solutions. I use modern software development techniques, such as:

  • a tight feedback loop with users and stakeholders
  • automated tests and continuous integration
  • automate technical tasks as much as practically possible

I use high quality open-source frameworks and libraries that are well tested and community driven. This means the frameworks and libraries that I select will be maintained and developed into the foreseeable future.


I work with business and technical stakeholders when creating technical plans and designing the architecture of a project. I offer technical choices with clearly stated pros & cons and cost / time implications for each of the options I propose.

I can also evaluate existing technical plans and architecture when a second opinion or additional input is required.


I can work on any stage of a project; from brainstorming and project planning with business and technical stakeholders to implementation and final deployment. This includes:

  • joining existing teams
  • developing full web apps
  • creating the base architecture to build upon

Simon Meijlink

Simon Meijlink

Senior Managing Partner at Oxyor Group

January 3, 2018, Simon was a client of Ben’s

Ben's recommendations and solutions saved us a tremendous amount of time and money by showing us how we could reuse parts of our existing stack and helping us setup the scaling we needed. Ben also trained and guided our team to make sure that people were comfortable supporting the application before he finished the project. Ben listened to our needs, developed a plan and executed it; consistently delivering high quality work.

Ben is capable of working independently and coming up with suggestions and alternative ideas that have been a major driver for our developments.

I loved working with Ben at 1%Club. His enthusiasm is contagious. He did a great job leading the team and managing people. Making sure everybody involved were on the same page. He understands the tools and the tech that he is working with in detail and is great at sharing this knowledge with others.

In the past year that Ben has been working on our Python/Django website he has shown an exceptional balance of experience, knowledge, communication skills, working ethic and the ability to work in a well structured manner.

Besides performing the tasks we needed him to do, he shared many valuable insights in the way the maintenance and development processes could be improved. He introduced new frameworks and libraries to the project, thereby simplifying and stabilizing the code base. Great changes were made while the site was continuously in production, all handled by him with care, flexibility and a keen eye for best practices.
