Drawing from a solid foundation in Python development and proficiency working with APIs, specifically the Keycloak API, I am well-positioned to take on and excel in your project. My vast experience with electronics, PCB design, MATLAB, embedded systems, and Arduino underscores my ability to handle intricate coding tasks, ensuring the optimal delivery of your project objectives in line with the highest industry standards.
The current code you've shared serves as an excellent starting point for this task, however, the objective of retrieving REALM and GROUP info for each user may benefit from enhancing the existing code or even building new functionalities - should you desire a 2nd Milestone. Given that we are time-constrained, I'll ensure speedy delivery without compromising quality or your satisfaction.
While I understand budgetary constraints can be limiting, I urge you to consider the value a perfect project provides. Nonetheless, I'm comfortable working within your $10 budget as I believe in mutually beneficial collaborations; one which culminates in a hearty exchange of stellar ratings. I'm excited about this opportunity and believe we can produce exceptional results. Let's create something great together!
