"A long time ago in a galaxy far, far away...." we started NFC subsystem refactoring. Starring: - @gornekich - NFC refactoring project lead, architect, senior developer - @gsurkov - architect, senior developer - @RebornedBrain - senior developer Supporting roles: - @skotopes, @DrZlo13, @hedger - general architecture advisors, code review - @Astrrra, @doomwastaken, @Hellitron, @ImagineVagon333 - quality assurance Special thanks: @bettse, @pcunning, @nxv, @noproto, @AloneLiberty and everyone else who has been helping us all this time and contributing valuable knowledges, ideas and source code.
