<aside> <img src="/icons/flash_yellow.svg" alt="/icons/flash_yellow.svg" width="40px" /> About Me

I'm a developer, red teamer(self-proclaimed), and entrepreneur who loves bringing ideas to life. I enjoy the process of building and breaking, whether it's writing code, security testing, or starting something new. My work is driven by curiosity, care, and a desire to create things that matter.
