xc4pr, WHOAMI? What I do: cybersecurity first, everything else second; wiring AI into fintech and crypto processes; preparing, cleaning and analyzing data; fine-tuning models and automating the boring parts; turning reporting and compliance into pipelines; running agents I steer from Telegram; self-hosting everything on Arch, btw; local LLMs on AMD GPUs: ROCm + Ollama; security-reviewing AI agent tooling; shipping Rust patches upstream

I build AI that does real work: agents, automations and the self-hosted stack they run on.
Mostly fintech and crypto, mostly on owned hardware.
If I do it twice, I script it. The third time, an agent does it.

whoami: xc4pr@homelab. OS Arch Linux. Terminal kitty. GPU AMD, ROCm for local LLMs. Stack Python, Rust, TypeScript, Bash, C#. Focus cybersecurity, agentic AI, data. Status building roomx and a voice co-pilot. Contact issues, PRs or socials.

> ls ~/work

What I do. AI x Fintech: implementation, fine-tuning and process automation in fintech and crypto. Data on autopilot: data, reporting and compliance workflows that run without me. Agentic AI: autonomous agents and coding-agent workflows with hooks, custom instructions and an Obsidian second brain; some take orders via Telegram. Self-hosted: local-first Linux on Arch, running on my own hardware instead of someone else's cloud. Local LLMs: inference on AMD GPUs with ROCm and Ollama. Favorite model: Qwen 3.8. Agent security: security reviews of AI agent tooling.

> cat pipeline.sh

How I work, as a loop: 01 idea, spot the boring part. 02 automate, script it or hand it to an agent. 03 self-host, run it on my own boxes. 04 ship, push, use, repeat. Then back to idea.
