    “Gustavo is the best Freelancer I have ever worked with. I knew what i wanted in my project but found it difficult to convey this in the projects description. he was very patient with me throughout the project and completed the job to a very high standard. I appreciate the way he kept his patience when i asked for things to be added that i hadn't conveyed in the description and his work was outstanding will definately use again”

    “((( BEWARE ))) Gustavo is the WORSE freelancer I've worked with. He blamed another developers coding and couldn't deliver 100% of the project. He thinks delivering code that is not responsive "mobile friendly" is acceptable. I paid him 80% = £200 and after further testing, I have just noticed that he has ruined an important component function that was not related to the original project. I now have to ask another developer to finish and correct the issues he has caused After he realised his technical ability wasn't up to the job, he kept saying "I can't help you with that you need to go back to the original developer" and demanded I pay him in full. Is this not why, we as employers hire freelancers to implement modifications and solve any problems they encounter. He constantly rants blaming everything else but his own work that clearly doesn't work and demands staged payments. His lack of diplomacy and online etiquette is shocking to say the least. If you want a constant headache and a sour taste left in your mouth then Gustavo is the Freelancer for you. You have been WARNED.”
