What is Denk Development?

Denk Development is a Zurich-based hardware and software development company, operated by me, Timo. I founded the company during the time I graduated from high school (in June 2016) because I started to receive requests for support with projects frequently. For five years I ran DenkDev as a secondary employment and have completed over 50 projects successfully.

In mid 2021 I started working for Google and decided to turn the company into a pro bono effort with which I support projects entirely free of charge. People seeking for support are invited to apply with their projects on this website and I choose depending on how interesting/challenging and meaninful the projects seem to me personally.

My motivation for running DenkDev in the pro bono mode is the following: I to get to work on projects ouside of the scope of my normal day-to-day work. That involves getting to know people who come from vastly different backgrounds. Pulling the monetary aspect entirely out of the customer relationship makes it more enjoyable.


Web · Python · Java


Arduino · AVR · ESP32

Some Example Projects

You are invited to take a look at this blog post listing a selection of five past DenkDev projects that were completed successfully.

Generally speaking, collaborations should typically have the following properties: (1) Be limited in their scope. (2) Be technically interesting. (3) Not have a conflict of interest with my main job at Google.

Below are some simplified dialoges which you might have with Denk Development:

Customer: I need to log some sensor data to an SD card with time and date.

Do you have the data format / what is the protocol?

Customer: It is an I²C (Inter-Integrated Circuit) sensor.

The systems needs an additional real-time module to provide time and date. I could do that in 3 hours.

Customer: Thanks! Here is the sensor name.

Customer: Can you write a small website that has a contact form?

Yes, I can do that with a PHP backend.

Customer: Perfect, how will it work?

If you want plain text emails, I would send them with the PHP mail() function. For HTML formatted emails, PHPMailer is a good choice.

Customer: Okay, sounds good, please get started.

Frequently Asked Questions

Why do you work for free? I enjoy being exposed to diverse areas of technology. By working for free I receive many project requests and get to choose what to spend time based on my excitement.

Which projects do you work on? Whether I pick a project depends first and foremost on my current (strongly varying) availability. Beyond that it matters how challenging and interesting the project is to me personally as well as whether I feel like I can help effectively.

How does software exchange work? Because many projects involve multiple testing cycles, code is generally exchanged via GitHub.

How does hardware exchange work? Simply sending packets.
