• Co-founded the company and played a primary role in setting strategic business direction, developing service offerings, and engaging with key customers to establish and expand our market presence.
• Conducted a detailed analysis of the Ethereum discv5 DHT, essential for peer discovery within the consensus layer, culminating in a comprehensive report on its reliability and key statistics.
• Maintenance of the company website, and infrastructure (Github, AWS, Postgres).

• Led a team in the development of a new libp2p DHT implementation, resulting in a system benchmarking significantly higher in performance compared to the previous implementation.
• Conducted comprehensive measurements on the decentralized IPFS network, including analyzing DHT health and Bitswap provider discovery efficiency; findings detailed in DHT Network Report and Bitswap Efficiency Report.
• Designed a privacy-enhancing upgrade to the IPFS DHT that separates requester IDs from content identifiers, significantly improving user privacy; see Privacy Design Spec. Submitted related findings to a conference (pending acceptance).
• Developed a novel Composable DHT design, offering universal routability to libp2p, while enhancing flexibility, scalability and security.
• Acted as the primary maintainer for the libp2p Distributed Hash Table (DHT) specifications and implementations (Go, Rust), ensuring its robustness and alignment with evolving community and industry standards.

• Design, installation and operation of globally deployed network security solutions, including SD-WAN, MDR, VPN, firewalls, secure proxies.
• Participation to 24x7 Mission Control support.

• Master’s thesis on Cryptographic Agility in the Post-Quantum Era, exploring the migration challenges from current cryptographic standards to quantum-resistant algorithms.
• Built a tool for Go libraries, creating a Software Bill of Materials (SBOM) to enhance the tracking and updating of cryptographic dependencies in software projects.
• Collaborated within the IBM Q Security and Encryption group, contributing to research that advances understanding and implementation of post-quantum cryptographic systems.

• Analysis of the Privacy ICAO Address (PIA) program from the FAA aiming to provide anonymity in General Aviation in the US.
• Demonstrated program weaknesses by tracking aircraft enrolled in this program using only public ADS-B data. Suggested privacy improvements. DEFCON Talk, Paper.

• Consulting engineer in the Routing & Switching team of Cisco Professional Services.
• Design and configuration of network topologies composed of Cisco devices.
