What I'm looking for

I seek engineering roles focused on secure embedded/IoT systems or research-driven projects where I can apply system optimization, security expertise, and mentor others.

I am a versatile computer science engineer focused on problem-solving, performance optimization, and secure system design, with hands-on experience in satellite communications, IoT, and GPU-accelerated solutions. I have designed secure communication protocols for CubeSats, explored security frameworks for resource-limited environments, and developed hardware-based security solutions while mentoring Master’s students.

I bring practical experience deploying servers, networks and virtualized infrastructure, enhancing diagnostic interfaces, and implementing client feature requests. I am collaborative, analytical, and experienced in team management and student leadership, ready to contribute to challenging projects requiring rigorous engineering and security expertise.
