What I'm looking for

I seek roles applying AI, mobile, and security skills in collaborative teams where I can build scalable, secure systems and grow technically.

I am a computer engineering graduate with hands-on experience across AI training, mobile app development, systems administration, and cybersecurity. I have contributed to autonomous AI agent training workflows, built Android and iOS apps using Kotlin and Swift with MVVM and Material Design, and managed networks and Docker Swarm environments while supporting security monitoring and incident investigation.

I deliver practical solutions that bridge hardware and software — from RF/PCB design and embedded systems to CNN models in PyTorch and AR educational tools. I thrive in collaborative, cross-functional teams, emphasize quality assurance and secure development practices, and enjoy tackling complex technical challenges that require innovation and rigorous testing.
