20 - 22 November: Hackathon

Roll your sleeves and start building ๐Ÿง‘โ€๐Ÿ’ป

24th November: Demo day

The best projects will present their result during the Demo Day.

We will end it by announcing the best project and the winner of the MacBook Air M2 ๐ŸŽ‰

Demo day

On 24th November we will host the Demo Day on our YouTube channel. The best projects will showcase their results and compete for the grand prize.

To participate at the demo day, you will have to submit a 2 minute long video presentation of your project together with a link to the GitHub repository. The submissions that follow the requirements will be played at the Demo Day, on 24th November, and our juries will vote for the best ones.

For the video presentation, we recommend following this structure:

  • (10s) Introduce yourself and the project in one sentence
  • (10s) Talk about the problem. Why is there a need for your application.
  • (30s) Talk about the solution. How are you planning to solve this problem. Here, you have the opportunity to show your vision for the project. You definitely wonโ€™t manage to build everything in just 3 days, but itโ€™s important to visualise how the solution will look in the end.
  • (1 min) Demo. Show us the main functionalities of your application. Even if not everything is perfect.
  • (10 sec) What are your next steps?

โ— The video should be maximum 2 minutes. In order to give everyone the possibility to present, we will stop the video presentations at 2 minutes.

The Deadline toย submit your project: 22nd November, 11:59 PM GMT

Submit your project for the Demo Day

๐Ÿง‘โ€โš–๏ธ Evaluation criteria

All projects will be judged by our juries.

The criteria will be:

  • The hackathon theme: Is the project related to the hackathon theme
  • The idea: The usefulness of the project in real-world
  • UI/UX: Keep it simple and consistent. There is not enough time to invest in sophisticated UIs and animations. The focus should be on simplicity, usability, and overall look of the application.
  • Realisation: The completeness and complexity of your project will be evaluated here. We recommend focusing on having the most critical features "workable" first.
  • Presentation: Your presentation skills


  • The project should be a Mobile Application build with any tools/technologies/frameworks you know best
  • The project should be started during the Hackathon. We will look at the GitHub history to make sure the projects are started and build during the hackathon. Pro tip: commit and push often.
  • You can work alone, or in teams of maximum 3 people

Anti-requirements, or what we donโ€™t expect:

  • You donโ€™t have to have a finished product. Show us the vision and the progress you managed to have during the hackathon. As little as it is, itโ€™s worth a shot.
  • You donโ€™t have to be a PRO to put together a small proof of concept. Look at it as a learning opportunity.

Feedback from our previous events

Our team is very thankful to you for providing us with such opportunity and recognition. We would love to collaborate with you on our idea and take your inputs to improve our product.

Good news, the app was submitted to the App Store and Google Play Store and was approved for both! So we are now officially launched

Thank you very much for the opportunity to participate in the competition. I saw very good startups there so I was surprised I won. Hoping to see more of these events in the future, in uncertain times like this you are truly helping out a lot of people and fostering talents. I truly believe that NotJustDev is going to be not just a youtube channel but a huge incubator that pushes the boundary of what's possible in the world of startups.

Sharing is caring ๐Ÿ™Œ

If you are excited about this event, help your network discover it as well. Invite your friends and learn together. It's more effective and also fun to learn together.

Thanks for all your support ๐Ÿ™

Hi ๐Ÿ‘‹ Let me introduce myself

I started my career as a Fullstack Developer when I was 16 y.o.

In search of more freedom, I transitioned to freelancing, which quickly grew into a global software development agency ๐Ÿ”ฅ

Because that was not challenging enough, I started my startup which is used by over 20k users. This experience gave another meaning to being a (notJust) developer ๐Ÿš€

I am also a proud ex-Amazon SDE and Certified AWS Architect, Developer and SysOps. You are in good hands ๐Ÿ‘Œ
