Java & Python Development Support

I need an experienced programmer who is comfortable switching between Java and Python codebases. The work will be organised in small, focused milestones: on some you may create new modules from scratch, on others you might track down a stubborn bug or hook the application up to a REST-style API... (Budget: $2 - $8 USD, Jobs: CI/CD, Git, Java, JavaScript, Python, REST API, Software Architecture, Software Development)
