A curated collection of cafes and coworking spaces around the world. I started maintaining my own collection of “good places to work from” and eventually turned it into a website.

Skysense helps you stop plant disease and weeds before the damage is done by providing agricultural intelligence from self-flying drones.

Simple and customizable. Invite users, give points, and offer rewards.

While spending a lot of time in Tokyo I built a small tool to help me check seat availability on Shinkansen trains. During one trip to Japan I bought a 2 week rail pass and spent 2 weeks traveling all around Japan. I wanted a simple, quick, easy to use that let me regularly check seat availability on Shinkansen trains so that I could plan my (mostly last-minute) travel. JR offer their own tool (previously only in Japanese, but now available in English as well) called JR Cyber Station. My tool just makes it a little easier to refresh my past searches.

The easiest way to find and monitor award flight availability across multiple frequent flyer programs. It started as a project to solve my own challanges that I faced while trying to figure out the best way to spend my airline miles. Today it has 1000+ customers and supports several different frequent flyer programs, with more on the way. Be sure to check out the blog as well.

A small tool that let’s you easily check share bike availability in Malmö, Sweden. It also supports setting up favorite stations, making it easy to quickly check availability along your most used routes. I built it while regularly using Malmö By Bike to/from a coworking space I was using in Malmö.

All your receipts, invoices, and payments in one place. It was my first project built as a One Week Build and posted it on Product Hunt where it became the #1 Product of the Day. Unfortunately the project is currently not accepting new users/customers due to changes that Google have imposed on API access to Gmail, which currently requires spending $15,000 to $75,000 for a security assessment.

Hyperbnb is a supercharged search for Airbnb listings. Features include more filters, sorting by reviews/rating, a computed “score”, and up to 300 listings at once. This project was also posted on Product Hunt and I also posted a One Week Build write up. Unfortunately the Airbnb endpoint I was using stopped working after a couple of years, so the app is currently suspended.

Glance started out as an idea to create a unified “company dashboard”, including various metrics such as Google Analytics, Social Media, and Stripe. Eventually we also developed a Slack bot (glancebot) that would integrate with your workspace to provide real-time metrics. After quite a bit of effort we eventually decided to shelf the project, but later ended up selling it to a new owner.

The easiest way to wrap screenshots in browser frames. Supports multiple browsers, operating systems, and themes. It was my second One Week Build also shared on Product Hunt where it became the #3 Product of the Day. I use it myself all the time (even here to generate the project screenshots), and it gets a pretty decent amount of traffic.

Turn your smartphone into a universal remote control. The goal was straight forward to create an easy solution in form of a remote app to controlling the programs on your computer through your smartphone. Today the app has nearly 10 million downloads worldwide, is rated among the top apps, and the numbers continue to grow!
