The apps are well structured and commented, use a python backend for data and some related microservices.
These are business apps NOT flash graphics / games.
The code was created by professionals and has been stable in AS3 for many years (as bug free as you can get with AS/3 flash).
Anyone here interested in quoting me for the work?
Obviously there will be some initial investigations into the code to establish the complexity / feasibility / time involved.
