A Himalayan Remote Engineer Tests Offline Coding Agents on a Laptop

A Principal Engineer at Thomson Reuters, living in the foothills of the Himalayas, experimented with running a local coding agent offline. Using the open‑source OpenCode tool with the Qwen3.5‑9B model served via Ollama, he was able to read project files, propose edits, and run test suites entirely on his Mac without an internet connection. The setup required pre‑downloading the model weights and project dependencies; tasks such as explaining functions, debugging tests, or refactoring small code segments could be completed offline, while operations that required external packages or web look‑ups still needed connectivity. The experiment demonstrates that developers in low‑bandwidth or disconnected environments can maintain a significant portion of their coding workflow using locally hosted AI agents.
