What I'm looking for

I’m looking for an early-career role where I can learn offensive cybersecurity in practice—testing systems, writing clear writeups, and collaborating on real security problems while building deeper systems and networking skills.

I’m an aspiring cybersecurity and systems professional with a strong interest in offensive cybersecurity. I’m working toward my CPTS certification, and I focus on learning by doing—especially where security meets real-world systems and behavior.

From a backend internship, I gained hands-on experience with REST APIs, performing endpoint testing and validation using Postman. I wrote and maintained unit tests, interacted with MongoDB for data inspection and basic operations, and supported debugging API issues to verify data retrieval behavior.

I also bring a developer’s mindset to security: disciplined testing, careful validation, and professional workflows. I plan to keep posting writeups and blogs about what I’m learning, the challenges I’m tackling, and how that translates into stronger offensive security and networking capability.
