Hanna Jacobsson Hosk

Summary

I specialise in system integration and business process automation. I'm driven by finding ways to simplify how clients work and reduce manual and repetitive tasks through technology and AI. My experience ranges from AI-driven systems and integrations to business platforms and other web-based solutions. Before changing career paths I ran my own business for several years, which gave me structure, attention to detail and a strong focus on client relationships.

Experience

How I work

Pull request pipeline

I built a small open-source kit that adds automated checks, an AI code review and a security review to every pull request. Low-risk changes merge on their own. The rest wait for my approval on GitHub, and Slack tells me when. It runs on my own projects.

Security

Secrets are kept in Infisical, never in the code. My AI tools reach outside services through one MCP gateway, MCP Jungle, with work and private tools in separate groups. Agents have clear rules for what they may do alone and what they must ask about first.

Backups

For projects with a database I aim for 3-2-1 backups: three copies, with two providers, one of them off-site. Copies run on a schedule, and I get an alert if one fails.

Agents

I am building personal agents, such as a personal assistant, a tech lead, and SEO and marketing leads. Each has its own instructions, memory and schedule, inspired by Hermes and OpenClaw. They share a second brain based on Karpathy's LLM wiki and Garry Tan's gbrain and gstack, and they report in Slack.

Setup

I run Claude Code in Herdr and Ghostty. Through herdr-web-ui and Tailscale I can follow and answer the agent sessions from my phone, and my machine stays awake so they keep running.
