  • image de mdiamond87 Write VBA code for Outlook 2016 $50.00 USD

    “Patryk was very helpful! He knew the relevant subject matter (VBA code for Outlook) and then a whole lot more. He accommodated me very well; when I didn't know what I wanted, he provided suggestions and solutions. When I asked how he did something and why, he told me and showed me the specific lines of code. When I asked for comments in the code, he commented every line! He was always available or he told me when he would be back. If you're wondering whether to hire him for VBA projects, it should be a definite yes. He got the job done in a timely manner for the right price. I also feel like I made a friend in the process. I'm currently discussing another project (involving javascript) with him - I have a feeling I won't need to look for another freelancer on here for a while, if ever! Thank you again, Patryk!”
