Portfolio

I love to build products that are helpful, easy to use, and delightful.

This page provides a brief overview of some of my ongoing or past projects. All of these products have been built, designed, influenced, or started by me.

Photone - Grow Light Meter

Photone is a light meter app that takes all the light measurements relevant for plants and is used by indoor gardeners around the world.

Building, improving, and marketing Photone is what I'm currently spending most of my time with. Photone is the most important product of my company Lightray Innovation and we take great care of it.

I continually learn a lot in building such a product at scale. It is available on both iOS and Android platforms, relies on a lot of scientific research and development, has web-integrated features, and is currently translated to six languages (and counting). The software is developed fully natively using Swift and Kotlin with another integral part being the website and blog that are built using Ghost.

Light Meter LM-3000

The LM-3000 is a simple and accurate light meter app for architects, photographers, and other professionals. The app is available on iOS and built using native technologies.

The LM-3000 came into existence as a stripped-down version of the Photone Grow Light Meter as a generic light meter. Behind the scenes, it's using the same measurement technology, which we've packaged as a reusable module. It's an – so far satisfactory – attempt in scaling our core technology across other verticals and an interesting study in managing our internal resources.

Belimo Cloud Frontend

With Belimo being a leading provider of HVAC field devices for the Building IoT (BIoT) industry, the Belimo Cloud Frontend is the central tool for configuration, monitoring, and diagnosis of all Belimo cloud devices.

This project has been my first concept-to-release software project in a corporate environment with a team of almost 50 people spread across Europe, Asia, and North America involved in it. Apart from the technical skills required, I especially learned how to navigate such an environment, how to coordinate change in a global company, the benefits of lean- and direct communication lines, and a lot more.

My Contribution

  • Product Ideation & Concept
  • UX/UI Design
  • Product Owner during initial development

My work began in 2020 and finished in 2022

Belimo Display App

The Belimo Display App is used to access Belimo sensors. With the intuitive end-user app, the current room values can be displayed and setpoints can be adjusted using wireless NFC.

Visit Website

The Display App project was brought up to me within Belimo as a visionary idea, where I then lead a small team of user interaction and user interface designers to create a validated concept for the whole mobile app. In contrast to other Belimo applications that I worked on, the Display App is targeted at non-technical end-users such as office employees or teachers. Therefore, we laid the focus on high intuitiveness with a low learning curve while still fitting into the efficiency-focused Belimo ecosystem.

das chili abo

The premium subscription box for people that like it spicy. The project was active for about two years and has then been stopped to pursue other challenges – and also save our taste buds.

Building the chili abo (German for "chili pepper subscription") was a lot of fun and a bit of a different challenge for me. It wasn't as much about software but rather about product selection, sourcing, packaging, and physical delivery. Ultimately, it wasn't for me yet still an important part of my journey.

The main product consisted of a monthly, hand-curated box full of chili pepper products, a brochure describing the products, and recipes. Our three product tiers (variado, picantivor, and connaisseur) each reflected a different kind of chili experience for beginners as well as long-term chili-heads. Our boxes were also available through the major Swiss online retailer Geschenkidee.

The website started from a simple HTML order form and later evolved into a full Shopify-based e-commerce setup.

insidr

A crypto trading sentiment platform and knowledge exchange. Unfortunately, I decided to drop the project before the product went live. Bye-bye Lambo, hello experience.

I learned a lot on this project, became a better developer, and ultimately more mindful: Sharding, scraping the web, building my first ever Ghost blog, and why I shouldn't start what I don't have the capacity to finish.

Insidr was meant to provide insights into crypto market sentiment and trading statistics with the goal to foresee future price movements. The main application consisted of a node.js-based backend with decentralized scraping services and an Angular frontend.

In addition to the actual market insight application, I also created a content-based Ghost website that included articles and tools such as a compound interest calculators and a cryptocurrency portfolio creator.

Rieglia HORTUS

Rieglia HORTUS has been the Rieglia product line of Internet of Things smart sensors and cloud applications. The rights have been sold in mid-2017 to the company that now is Akenza.

Visit Website

Still one of my most important projects, that significantly shaped my trajectory. Rieglia was my first startup, which started with the idea of measuring plant well-being remotely. I teamed up with a long-time friend and we quickly discovered that the then new-and-upcoming LoRaWAN low-power wireless network may be an interesting fit and started developing our hardware-, firmware- and cloud platform. Fast-forward a few months and we were a partner of the biggest Swiss telephone company Swisscom before the official launch of their nationwide LoRaWAN network.

In our search for venture capital to fund our hardware production (we only produced prototype batches of 40 sensors so far), we got to know the team that now became the joint-venture Akenza.

My initial focus was very technical with first writing the whole cloud (device gateways, data storage, message queues, and client API) in Java and then completely rewriting it in node.js a few months later. After that, we extensively talked to potential partners and clients, which shifted my focus to the marketing and management side before then ultimately selling the rights to our intellectual property. It was one of the best things that my then 21-year-old self could've done and I learned a lot that heavily influenced my approach to people, products, and businesses.

That's it for now. There have been other (possibly secret 😉) projects along the way, but these are the most important and impactful ones to me. I am very grateful for all the excellent people I've had the chance to work with and everything that I've learned while doing so!
