Cost of project was not small. We agreed to bring light of project on table at a level of 20% of payment. The rest of amount of days were spent on understanding how and why it works. Freelancer was keen to solve any struggle. However, there was constant supervision required: Founding bugs and re-pinging the freelancer to fix that. Configuration files were not crispy clear. Mixed software versions.
