Hey! I'm Mark Gregory Plantado, aka mk-gg, a 27-year-old software developer from the Philippines. I work mostly with Python, Java, and the AWS ecosystem, and I gravitate toward backend work: APIs, automation, and infrastructure that quietly does its job.
Previously I built a Discord moderation platform at Sky Mavis that protected a 120k+ user community from phishing and scams, and more recently I've been training AI models and shipping side projects like Pasquin . When I'm not coding, you'll probably find me queuing up another game of TFT.
