Lean Landing Page

Your essential tool for product validation

Astro
Tailwind CSS
Matomo

A landing page is a crucial tool to figure out who your customers are and what they need. It is a small investment that ensures that you are going build the right thing before you make the big investment in building it.

My lean landing page comes with all features you need to get this validation. You can use it to find your target audience through campaigns, as a basis for user interviews and as a clay model to form the product.

All user interactions are monitored through the privacy-friendly Matomo analytics solution that shows you where your users come from and how they interact with the page.

See the example on checkly.letsbuildtogether.dev.

Diagnosis Tool

Speeds up embedded development

VueJS
VuetifyJS
NodeJS
Docker
REST
Raspberry Pi

In embedded development, adjusting configura­tion values usually requires a complete re­com­pi­la­tion and loading of the code onto the micro­controller, which is time-consuming.

With Diagnosis Tool, I developed a system that allows values to be read from the prototype and ad­just­ed at runtime via a convenient web app.

This significantly accelerated both the de­vel­op­ment cycles and the usability testing for my client.
