Autonomous Paperclip is a Phase A research experiment for Grinviro exploring autonomous AI agents, built on an open-source fork of paperclipai/paperclip. I configured a three-tier agent hierarchy — Director AI (Claude Opus), Manager AI (Claude Sonnet), and Staff AIs (DeepSeek) — and validated a complete end-to-end autonomous workflow from task submission through AI delegation, implementation, code review, and automated release to production. The experiment successfully proved that a fully autonomous, human-in-the-loop multi-agent pipeline is feasible across the software delivery lifecycle.

InnerSpace is an AI-powered, web-based stress monitoring platform where participants submit data through three modules — daily diaries, video logs, and questionnaires — so experimenters and psychiatrists can track stress conditions over time. Its core AI capability is automatic facial emotion detection on the uploaded video logs: each recording is analyzed to recognize the participant's emotional state, and the results feed into the platform's stress analysis to surface emotional trends alongside the diary and questionnaire data. Built with a Next.js (React + Material-UI) frontend and a Laravel REST API, the system supports role-based access for participants, experimenters, psychiatrists, and an admin.
