I'm a content writer and video creator, specializing in video games, as well as a game dev. Primarily, I write and create review videos that I upload on my budding YouTube channel. In addition, I'm an aspiring game dev that documents my journey on YouTube as well. (Please check below to see my work!) If you need a content writer for anything and everything related with video games then I'm the perfect choice. While I may specialize in reviews, I'm versatile and can craft easy-to-follow guides, fun list articles, and quick news pieces about all things gaming. I really know my way around the gaming industry and like to keep myself informed so you're getting expert insight and attention to detail every time. My time making videos also helps with my understanding of SEO with good titles and well-made thumbnails as well as the video-editing process. I've used Kdenlive extensively and have recently (about 1 year as of this writing) started using DaVinci Resolve to edit my videos. So please consult me if you need help with any video creation. Finally, while my game dev skills are basic at the moment, I'd be willing to help out in anyway that I can when it comes to testing a game and providing feedback, some light programming tasks, game design ideas, and, of course, game narrative writing. I'm always eager to learn more in the game development industry and would love to work with you!
