what i can build for you
AI & GPU infra
Local model orchestration, OpenAI-compatible servers, multimodal pipelines, agent frameworks and MCP tooling — running on your own hardware.
Reverse engineering
Black-box protocol analysis and clean-room interop clients. Network captures, wire formats, firmware — turned into working, maintainable code.
Systems & embedded
C/Python daemons, Linux internals, ESP32/Arduino firmware, PCB & hardware bring-up, home automation and industrial I/O.
Full-stack & self-hosting
APIs, real-time web apps, PWAs, streaming, WordPress & commerce, plus the ops to run it all yourself — TLS, TOR, containers, packaging.

open sourcerun every model on your own GPU
A multimodal, multi-backend local model orchestrator with a drop-in OpenAI-compatible API. NVIDIA (CUDA), AMD & Intel (Vulkan), on-demand load/unload, VRAM→RAM→disk offloading, and a full Web Studio for chat, image, video, audio, TTS/STT and custom pipelines.
bsdrX
Bigscreen RDcast any screen into a VR headset
A clean-room Bigscreen Remote Desktop agent, reverse-engineered from observed behaviour. Casts screen + audio into a Bigscreen VR headset over LAN or the cloud relay, on Linux, Windows, macOS and Android from one portable C core — plus 2D→3D, face-swap, voice changer and LLM voice control the stock host doesn't have.
AISBF
live · freeAI Should Be Free
An AI service-broker framework: one unified API in front of Google, OpenAI, Anthropic, Claude Code, Ollama, CoderAI, RunPod and more — with intelligent routing, a provider marketplace, a multimodal Studio, wallet/billing and adaptive rate-limiting. Hosted free at aisbf.cloud, TOR-reachable, and pip install aisbf.
grappa-irc · shottino
open sourcemodern IRC, without making it not-IRC
An always-on IRC bouncer with a REST-first API (grappa, Elixir/OTP) and an irssi-shaped PWA client. I build shottino — its native Linux terminal client in C/ncurses that speaks grappa's JSON + Phoenix Channels surface, never parsing IRC itself.
$ ./let-me-build-your-thing
Got a protocol to crack, a model to self-host, a daemon that has to just work, or a product that needs an experienced pair of hands end-to-end? That's my idea of fun.
