$25-50 AUD / hour

We have a cryptocurrency exchange that hosts Bitcoin, Ethereum and a few ERC20 tokens. The site is currently on maintenance due to flaws in the security of the exchange. In addition parts of the exchange data reporting are deficient and also lacks an audit system. The exchange has five servers that have all the functions required to host nodes, user interface and database.. The operating system is Ubuntu v18. The primary tasks required are: 1. Identify and fix security flaws. 2. Create Audit reporting 3. Expand admin reporting features across users and transactions 4. Document the entire exchange processes and dependencies 5. Provide additions to the Administration UI to allow better management of the exchange 6. Provide additions to the exchange interface to allow promotional activities to users 7. Provide additions to the exchange interface to allow referral activities for users 8. Other modifications as needed on an ongoing basis. To be considered for this project, you must have a strong experience in Laravel, PHP, mariaDB, and previous experience in managing security within a cryptocurrency exchange.
