Biography

🔐 Security Awareness. 💻 Software Development. 📫 Open-mindedness.

I am proficient in software engineering using Javascript, C/C++, and Python. Currently, I am studying Javascript Fullstack Engineering @ Chas Academy to further specialize and formalize upon my prior personal experience using Typescript, Bootstrap, HTML/CSS, Docker, Node.js, Express.js, MySQL, and more.

I am also enthusiastic about Linux system internals and have prior personal experience in system administration. In my spare time I research into different topics such as cyber-security and how software and hardware work. I have found an artistic joy in digital design creation using Affinity Design.
