My favorite tools for designing are Adobe Photoshop, Illustrator & InDesign CC. The software that I use depends on the context. I have done a lot of designs for both my school and external organizations. My designs are mostly customized to the client's needs. Say you need an impressive poster for a company formal event which requires the hosts, guests of honors, sponsors to be highlighted clearly - I am able to do that for you. So it would be great if you do have a specific preference for the designs that you want, but otherwise we can work it out together as well. I can show you references or create mood boards for you to understand better how you want your subject to be presented and expressed to your target audience.
