AI automation and developer tools — built in production

What We Build

AI Automation & Developer Tools
From Production Systems

Real workflows, real infrastructure, real code. Everything here is built and tested in production — not tutorials written from docs. Self-hosted, open patterns, built by a team that ships.

AI Automation

Production n8n workflows, Claude API integrations, MCP servers, and AI-powered pipelines that run in production.

Infrastructure

Docker stacks, Proxmox homelab builds, monitoring, backups, and security hardening. Own your stack.

Dev Tools

CLI tools, starter kits, workflow templates, and developer experience patterns that save hours.

System Design

API architecture, database schemas, caching strategies, and the trade-offs behind scaling decisions.
