About Me

I am a software engineer and MSc Data Science candidate at the University of Basel.

My work combines software engineering, artificial intelligence, distributed systems, privacy-preserving machine learning, and high-performance computing. I enjoy transforming technical ideas into practical systems—from inventory platforms and AI support tools to differentially private models and parallel algorithms.

Through Denxhinjo Labs, I document selected products, academic research, and engineering experiments.

  • MSc Data Science candidate at the University of Basel
  • Interested in AI engineering, distributed systems, HPC, and full-stack development
  • Currently exploring peer-to-peer navigation and traffic dissemination

Current Focus

Peer-to-Peer Navigation

I am exploring a decentralized navigation system in which nearby users exchange traffic conditions and hazard alerts directly rather than relying entirely on a centralized traffic-data service.

Current areas of investigation include:

  • Rust and iroh networking
  • Geographic topic-based dissemination
  • Peer discovery and NAT traversal
  • Location privacy
  • OpenTripPlanner routing
  • GTFS and OpenStreetMap integration

Privacy-Aware Machine Learning

I am also interested in the practical relationship between:

  • Differential privacy
  • Model utility
  • Membership-inference resistance
  • Fairness
  • Deployment constraints
