A multi-agent operating system that takes a business from idea to live, tested and marketed product. Local document grounding keeps private source material close, while specialized Gemini agents coordinate research, legal, brand, build, sales and support.

• Gemma 4 local vault ingests documents, performs OCR and grounds agents in real business numbers.
• Seven specialized agents work in parallel with conflict resolution before changes ship.
• Plain-language Antigravity edits continuously update the live product while team context stays permissioned.

A natural-language package manager and error watcher for Linux. Novato translates what users want into distro-aware commands, explains failures in plain English, and keeps working with an offline fallback when the internet is unavailable.

• Intent-to-command search detects the distro, ranks packages and shows the exact command before execution.
• A silent shell watcher speaks only when a command fails and offers a practical fix.
• Basic rules, local llamafile and online Groq backends form an automatic four-mode fallback chain.

An end-to-end IoT bell automation system pairing an ESP01S and relay module with a Flutter Windows desktop app, replacing manual bell operation with schedule-driven, remotely controlled ringing.

• Flutter desktop app packaged for Windows with MSIX for simple campus deployment.
• Firebase Realtime Database dispatches bell commands to the ESP01S over Wi-Fi with sub-second latency.
• ESP01S + relay hardware handles the physical bell trigger reliably from scheduled or remote commands.

An autonomous escrow platform where three competing AI agents negotiate deals through a weighted optimizer, while an ARC-4 smart contract handles fund locking and release on Algorand — no human intermediary required.

• Three competing agents negotiate deals via a weighted optimizer with autonomous on-chain settlement.
• Self-hosted LLM inference stack (vLLM + ROCm) with a 3-tier fallback chain for reliability.
• ARC-4 smart contract handles trustless fund locking and release on Algorand.
