    Admitted in Western Australia Supreme Court as Barrister & Barrister/Solicitor with the High Court of Australia/Federal Court & practicing in NSW Australia since 2006. I am specialized in litigation IP. I also do commercial negotiation and am involved in carbon credit origination. I do advisory on due diligence on the project and its proponents. My other interest is in coding hence I do due diligence on system security and ready pentester. Hence, if you want someone to look at your system be it on the cloud or on-premise, a thorough check will be necessary at least once a month as I can be the "gap" between IT and legal. Recently I came across a user who told me the reason why he wanted to use Upwork and not regular law firms ie believing lawyers here are cheap. To avoid doubts, I speak for myself here, lawyers on Upwork are not "cheap', most of us have elected to offer our services here because we wanted a different lifestyle. I also happen to be interested in new stuff like IT and AI which is not commonly found in a traditional firm. IF you want cheap, I suggest you go to find a fresh lawyer with 2-3 years of experience. You can check by looking at the law society website listing when a lawyer is admitted (in NSW). Other states do not provide this information. Lawyers with fewer than 2 years would also need to be supervised in Australia as they do not have unrestricted practicing certificates. I also come across clients who refuse to pay even though services were rendered. So there are good and bad actors around be it lawyers or clients. Just have to be careful when you deal with parties on line as you never know who they are.
