    “Tomasz is a highly skilled developer and his expertise was also very helpful in creating a Siri/Google Assistant voice controlled application using React Native. This was done to a very tight deadline and we weren't sure whether it was even possible! Tomasz is very dedicated and is always willing to research complex ideas and bring them to life.”

    “Our mobile app project would not have been a success without Tomasz at the helm of the mobile team. His insights into the mobile development process were invaluable. I had experienced the woes of getting apps approved with another startup, and Tomasz made the process look easy; getting our Google Play listing approved almost instantly, and diligently working to jump through Apple's hoops to get us on the App Store.”
