Betfair API Integration with Existing Code -- 2

I'm looking for a seasoned developer who can connect an existing source code with a Betfair API. The expert would need to be versatile with popular languages such as Javascript, PHP, Java, and others.

The initial task will involve:
- Fetching data from the Betfair API
- Executing bet placements on the Betfair platform using data fetched
-reflecting the entire data as exactly as possible ex: https://www.skyexch.art/
https://bxawscf.skyfair.vip/

I have purchased license of betlab from codecanyon.

Access and necessary credentials to the Betfair API have already been acquired, hence we can get started at once.

Ideal candidate should have:
- Proficient knowledge of Betfair API functionalities
- Proficient in Python, PHP, Java, or similar languages
- Experience in integrating APIs with existing code
- Strong understanding of betting platforms, preferably Betfair

Please include examples of previous similar projects in your proposal. Looking forward to a successful collaboration.
