Work Terms
Mostly available part time, but depending on the project emergency I've been known to stick overnight or as long as needed until the project is finished. Regarding payments: Payment rates and dynamics are subject of negotiation, but at the end client's satisfaction is a priority. I will not require any payments if I personally or the client is not satisfied with the result.
Communication is always according to www.guru.com rules. Skype or remote screen sharing is a common way to communicate on active project. I preffer two-way communication with the client on daily basis as the project progresses.
During project negotiations and consulting I always tend to give suggestions to client in order for the project to be as cost effective as possible, there are many cases where I reject the project and advise the client for cheaper or
already existing solution that will do the job.
I provide unlimited period of warranty for my work, all clients are free to contact me at any time for their issues, minor improvements, consulting within reasonable limits and I'm always happy to cooperate.
