IT professional with a background in operations, systems support, and middleware environments. My experience includes working with real-world systems under pressure — handling incidents, escalations, and cross-functional coordination. This has shaped how I approach problems, focusing not just on resolution, but on identifying patterns, root causes, and opportunities for improvement. I am currently transitioning into cybersecurity, developing both offensive and defensive capabilities through hands-on labs (HTB, CTFs) and structured learning (Sec+, CySA+, Pentest+ roadmap). My goal is to operate at the intersection of: - Security - Systems thinking - Detection and resilience - Business impact and decision support Portfolio: https://gitlab.com/obsidianorder/Portfolio
