Docker Compose CI/CD with GitHub Actions: A Reliable Flask Workflow


Elena Daehnhardt ·

Tests that only run on your laptop tell you very little about what ships. This post builds a Docker Compose CI/CD pipeline for a small Flask and PostgreSQL app: every pull request is tested against a real database, every merge publishes the exact image that passed, and that image is deployed to a VPS by its digest, behind an approval gate, with an automatic rollback if the new release will not start. Every file you need is in the post. Read more...

Elena Daehnhardt ·

A step-by-step guide to running large language models entirely on your own hardware with Ollama and Open WebUI, then adding a private RAG pipeline — and why a summer of model bans and metered billing made owning your own stack feel like the sensible default. Read more...

Connecting Codex CLI, Cursor, and Antigravity via MCP


Elena Daehnhardt ·

I was maintaining three separate integrations — one each for Codex CLI, Cursor, and Antigravity — until I moved them all behind a single shared MCP server. Here's how one LangGraph orchestrator now serves every client without duplicating approval, file-writing, or retry logic. Read more...

How to Run a Multi-LLM Stack as a Team of One


Elena Daehnhardt ·

With open models polarising into 2.8-trillion-parameter giants and sub-4GB pocket reasoners, hardcoding API clients is officially a production anti-pattern. Here is how to build a unified, resilient AI gateway layer in 10 minutes using Docker and LiteLLM. Read more...
