Mark did for us a very poor translation, which was full of errors, missing, typos, etc. It was rejected by our client. We had to hire another translation to redo it 100%.

Great translator and very easy to work with. Always delivers on time!
Awful experience. Worst EVER at Proz. This person claimed he could do a simple translation NL/SP(SP) and delivered a Google Translate document. Poor excuses. Awful communication.
Every time we work together, I learn more on his amazing skills and versatility.
Incredibly quick! I will definitely work with him again.
We worked with him on many projects.Mark was qualified and professional.
