Systems, platforms, and research-backed experiences that balance technical depth with clarity and usability.
A local-first, zero-knowledge desktop note-taking app. Notes stay encrypted at rest, with P2P sync over local Wi-Fi through mDNS discovery and WebRTC. The architecture keeps receiving devices unable to read notes without the user's derived key.
A production-grade cryptography learning platform with JWT auth, refresh-token rotation in HttpOnly cookies, hashed refresh token storage, and three-tier RBAC. The frontend includes live Caesar, Base64, SHA, and RSA tools plus progress tracking.
Full-cycle migration of a PHP/Laravel prototype using phased parallel-run deployment, remediating vulnerabilities for 500+ active users while strengthening IAM and database security protocols.
A Unity VR simulator featuring real-time physics-based mesh slicing, XR interactions, and tuned performance for reproducible demos across headset workflows.
A secure multi-service API for a constrained IoT device and POS backend, featuring service-to-service authentication, payment integrations, webhook handling, and failure recovery.
An autonomous UAV prototype built with ROS, embedded Linux, and Python/C++ pipelines for real-time sensor fusion, disaster identification, and emergency alerting.
Academic projects, research studies, and explorations that complement the core engineering work.
A Beyond Real VR study that explored how immersive game mechanics could support acrophobia-related scenarios and height-fear reduction.
A human-robot interaction study using the NAO robot to examine toddler emotions, play responses, and social engagement patterns.
A usable-security case study that examined online identity-fraud experiences in banking and social media and translated the findings into safer warning patterns.
User-experience research for connected-device concepts, bridging embedded systems, hardware interaction, and product design.
