Freelance Legacy Modernization Programmer: Migrating Monoliths, Python 2/3, FileMaker & EC2 to Cloud

Many profitable enterprises run critical operations on aging infrastructure: on-premise FileMaker databases, Python 2 Google App Engine monoliths, unmaintained Django/Java codebases, or expensive always-on EC2 instances. Rewriting everything from scratch is rarely the right business move—instead, a Senior Freelance Legacy Modernization Programmer uses the Strangler Fig pattern, bidirectional sync middleware, and incremental containerization to modernize without disrupting revenue.
