Work

Built alone, end to end — from the first line to the thing running.

  • Models · Prisma

    Prisma

    A small open-source organisation I run. It trains and releases open models. Everything is built and maintained by one person, which sets the constraint: small models, tight data, no budget for waste.

  • Inference

    Local LLM stack

    A local inference setup built on llama.cpp with my own model and provider configuration, plus Qwythos on top. Running models on my own hardware taught me more about their real limits than any benchmark did.

  • Security

    Red-team environment

    A test environment for attacking my own software and local endpoints before anyone else does. Fuzzing, prompt injection, misconfigured services, exposed local ports. Everything is run against systems I own.

  • Security

    Incident repository

    A documented analysis of a real malware incident: what got in, what it touched, how it was contained, and what I changed afterwards. Written up as a reference so the same class of mistake stays fixed.

  • Agents

    Agent and automation systems

    Orchestration for AI agents and the automation around them: task routing, tool access, recovery when a step fails. Most of what I believe about agents comes from watching these break.

  • Games

    Roblox game and mod work

    Where I started. A full Roblox game with a custom interface and an in-game economy — currency, sinks, shop flow, server-authoritative logic — and a separate game mod whose interface layer I rebuilt from scratch. First place I learned that shipping to real users is a different discipline from writing code.
