Hi there. I have 25 years of professional SW experience plus about half that again as a hobbyist, mostly in C. My main speciality is embedded SW, but I have also written compilers, editors and other text processors. Projects have ranged from automotive to scientific instruments to model railway control systems. For examples, if you are curious, you could google the "Cary Eclipse" or visit my hobby website modelrailmusings,weebly.com. I can also provide my full resume on request. I am based in Melbourne, and am currently involved with starting up a small business so a bit of simple, relaxing work would be welcome.
Your basic project (parsing the cinema XML and feeding it to the display hardware) looks quite straightforward, though as always the devil is in the details - it depends on how well matched the raw content is to the display's basic features, what the Polish SW does and does not do, etc.
Your open-ended extended project is also the sort of thing I am quite good at - using a bit of imagination and finding out just what a device can be made to do.
You haven't mentioned what development environment, tool chain, etc. is required. I am currently mainly set up for work on Windows and PICs, but others can be accommodated.
Regards,
Martin K.
