I use Adobe family CC 2020 for video editing & montage. I have a very good experience specially with Premiere pro, Audition, Photoshop, After effects & Illustrator. I tried my skills to do charitable videos & promotions for non-profit organizations which was very good.
I didn't have a certified certificate but I had learned & worked with the above programs starting from almost 6 years ago.
I had a past experience with movie maker, Sony Vegas pro, Sound forge (7 years).
