What I'm looking for

I seek an IT role focused on cybersecurity or systems work in a collaborative company that values learning, mentorship, practical impact, and opportunities to grow technical expertise.

I am a technology enthusiast with a background in education and frontline roles who is committed to continuous professional growth in IT. I have earned multiple certifications including Microsoft Azure Fundamentals (AZ-900), CompTIA Security+, Google IT Automation with Python, Google AI Essentials, and Google Cybersecurity Professional.

My hands-on experience spans system administration basics, Python, SQL, SIEM, intrusion detection, network analysis, cryptography fundamentals, and generative AI tools. I pair technical interests with strong soft skills: teamwork, communication, adaptability, and working well under pressure.

I am actively seeking opportunities in the IT sector where I can contribute in collaborative environments, quickly learn new technologies and methodologies, and grow professionally while delivering measurable value.
