Engineer & researcher
Secure backend systems and trustworthy machine learning.
For 6+ years, I’ve turned operational needs into maintainable software. Alongside production engineering, I research dependable intrusion detection for network and IoT environments.
I own work from discovery and architecture through data modeling, implementation, testing, deployment support, and maintenance. My strongest delivery work combines Python, Django, SQL, Celery, Redis, and Docker with clear operational safeguards.
My security research examines uncertainty, calibration, asymmetric error costs, distribution shift, and federated learning. I design configuration-driven, reproducible evaluations that measure operational risk—not accuracy alone.
