About us
We are two developers from Sweden who have teamed up to solve our customer's challenges. Our assignments are a mix of shorter troubleshooting projects, longer maintenance projects and development of new products.

Gwen grew up in Torsby in the 1990's and has worked as a developer for over 20 years.
Natalie Davallius
2021 M.Sc. degree in Computer Science & Engineering

Example assignments
Trouble with WiFi connectivity
A company with presence in grocery stores and convenience shops in multiple countries contacted us about problems with their device's WiFi connectivity. Gwen (amateur radio callsign SA6GWE) used a HackRF One to simulate radar pulses and was able to trace the problem to a use-after-free bug in hostapd. She submitted a patch which was merged by hostapd upstream, which fixes the crash. She integrated this fix and a few more in the client's Yocto layer and successfully stabilized the WiFi connectivity.
NI DAQmx C++ modernization
A company with cutting-edge technology that's used by researchers internationally contacted us about the deprecation of one of NI's computers. Natalie was tasked to develop a system image that would work on the replacement computer. She used debos to build a Debian-based image that embeds the NI Linux drivers and the customer's applications. After debugging several bugs and poorly documented changes in the drivers, she successfully ported the C++ applications to the new platform and found ways to dramatically increase performance.
Contact and availability
We are currently fully booked until November 2025, but Natalie has two days per week she could work on a parallel assignment.
