What I'm looking for

I'm looking for a backend-focused role where I can build secure APIs and distributed systems while growing in AI and cybersecurity.

I've built secure backend projects including a real-time messaging platform with Node.js, Express.js, JWT authentication, WebSockets, and MySQL, alongside a modular .NET security gateway for AI agents.

For my bachelor's thesis, I integrated and benchmarked post-quantum digital signatures including ML-DSA and SLH-DSA against Ed25519 across Windows, Linux, and macOS. I've also contributed to the LenaSYS educational platform, migrating legacy jQuery functionality, debugging features, and collaborating through pull requests and code reviews.

I'm a recently graduated computer science developer focused on backend development, distributed systems, AI, and cybersecurity.
