Frshly (http://gofrshly.com/) - Rewrote their entire tech stack from scratch. This consisted of a central HQ backend. Clients are geo-distributed with various responsibilities. The food outlet consisted of a local server and a mobile app. The restaurant had a tablet app and a printer service. Designed and implemented all of the services.
TouchGuide (http://www.touchguide.se/) - Revamped their map navigation software. Converted the entire stack into proper 3d maps using Three.js. This included parsing raw floor plans in svg, converting to a 3d model and loading, displaying the scene.
Skysense (https://skysense.aero) - Built a data streaming cloud service which consumes data from ADS-B receivers and relays the position data to an in-browser app for the users. The entire architecture used Kafka as the central queue backplane. With data feeding from the receivers, multiple services consumed from Kafka and pushed to their own storage layer.
