Hi, I'm a developer with more than 30 years of experience, most of it using Delphi as my main development language (yes, since it was Borland's Turbo Pascal). I'm also an Android Developer using mainly Android Studio (although I have developed using Delphi+Firemonkey too). I have very limited experience using Adobe AIR's runtime, not for games, but for an simple iOS/Android tutorial. At the time I used AIR, only software rendering was available, I understand it's much faster now that you can use GPU rendering.
I'm sure I can help with your project, I'm very experienced developer in both Delphi and Java for Android. I also have expertise with OOP and design patterns. You would need to consider the fact I'm not (and have never been) a game developer.
Please note that my offer is on a per-day basis (based on approx. 4 hours of work). If you open a chat, I can provide my CV (with verifiable references), and we can further discuss your project requirements.
Best regards,
Marco García
