// FIELDWORK

Proof over promises.

Case studies from GRC, detection engineering, homelab infrastructure and a few creative builds. Each entry keeps the same shape: context, role, what shipped, and the outcome.

CYBERLEARNThe platform I keep coming back to. A full-stack cybersecurity learning environment where the hard part was never writing the lessons — it was making progress feel earned and keeping a multi-tenant database honest about who is allowed to read what.
NULLSECThe site you are reading. An editorial-brutalist portfolio built under deliberate constraint — five colours, no gradients, three typefaces — where the content is typed data and the CVs are compiled from source.
ZERO TRUST ARCHITECTUREDesigning a Zero Trust migration for an organisation that already exists is a different problem from designing for one that does not. NIST SP 800-207 describes the destination clearly. It says almost nothing about the journey.
SPACE GRC MISSIONRansomware in a satellite company is not a ransomware problem. It is a question of which systems you can afford to lose, for how long — and what the answer looks like for systems where the answer is not measured in hours.
CRYPTOGRAPHIC AUDITCrappy Safe is not a creative name for vulnerable firmware — it is an accurate description. The password check compared characters in sequence and returned failure on the first mismatch. That single design decision turns the authentication routine into a measuring instrument.
HOMELAB · PROXMOXA small Proxmox homelab on a laptop — Ryzen 7, 16 GB, 512 GB NVMe — running real workloads: game servers for friends, a Wazuh stack, and a provisioning box for testing.
TOWER DEFENSE GAMEA fantasy, Dungeons & Dragons-flavoured tower defense built in Unity — currently at pre-prototype, with my work spanning development, UI/UX, and VFX authored as code in C#.
