What I'm looking for

I am particularly interested in software architecture, DevOps, network engineering, cybersecurity, and artificial intelligence. I enjoy working on systems that require both software and infrastructure expertise, especially where automation and performance optimization are key.

I am a Software Engineer and Senior IT Systems Engineer with over 8 years of experience working across software development, infrastructure management, networking, automation, cybersecurity, and machine learning solutions.

My career started with Linux system development and IT support, where I gained strong foundations in server administration, scripting, hardware maintenance, and network management. Over the years, I have progressed into building and managing software systems, mobile applications, backend services, and enterprise infrastructure.

In my current role as a Senior IT Systems and Support Engineer, I work on ISP infrastructure, network monitoring, system reliability, and automation. I have contributed to improving network performance, developing internal tools for monitoring and diagnostics, and implementing solutions that improve operational efficiency.

I have also worked as a Software Engineer and Machine Learning Consultant, developing web applications, mobile applications, AI-based systems, and automation solutions using technologies such as Python, Django, Laravel, Node.js, React, Flutter, and modern database systems.

Some of my key interests include software architecture, DevOps, cloud and server infrastructure, cybersecurity, artificial intelligence, networking, and building tools that solve real-world problems. I enjoy learning new technologies, improving existing systems, and working on projects where technology can create measurable impact.
