Looking for an experienced Magento developer to troubleshoot, fix bugs and develop new features. If the first tasks are approved, this should be a long-term job, with work from time to time.

Initial tasks:
1) resolve issue with the payment gateway and/or checkout page (must search for issues in the logs and present the problems, then proceed to fix the bugs)
2) analyze logs and fix bugs that result in repeated log entries
3) find performance bottlenecks and describe them, with proposed solutions
