Rune Tech
Backend-first developer. I build APIs, reverse engineer them, wire in LLMs where they actually help, deploy on self-hosted infrastructure, and automate what shouldn't need a human.
What I Work With
Selected Work
Internal license key and client access management system built for my own freelance workflow.
Mapped undocumented mobile and REST APIs using traffic interception and dynamic instrumentation. Built private automation clients on top.
Built device automation pipelines using ADB and Magisk-based tooling for programmatic control and process automation.
AI Integration
I build systems that use LLMs as a core component — not just wrappers around a chat endpoint.
OpenAI, Anthropic, and Gemini APIs. Streaming, batching, retry logic, cost control.
Getting structured, typed, reliable output from LLMs using function calling, JSON mode, and output parsers. No hallucination-prone freeform parsing.
Replacing manual workflows with LLM pipelines — classification, extraction, decision routing, and multi-step agents.
Tools I use: LangChain · Structured Outputs · Function Calling · Prompt Engineering · FastAPI + LLM backends
Self-Hosted Infrastructure
I don't just deploy to the cloud. I run my own stack.
Managed with Nomad + Docker. Reverse proxied via Traefik.
Monitored with Grafana + Loki. VPN access via WireGuard.
