Software developer: I build web applications, automations and AI agents that operate real software. I also bring 7+ years of BIM experience on large-scale engineering projects.

Built for older adults and people with little digital experience: the user speaks, and Asirea operates the software for them through browser automation, in Spanish or English, switching language turn by turn. Everything runs on local hardware, with no cloud APIs: no user data is sent to third-party AI services.

• 👂 Ear: my own voice activity detection on top of sounddevice, and speech-to-text with faster-whisper
• 🧠 Brain: language understanding and decision logic, running locally with Llama 3 8B via Ollama
• 🗣️ Voice: text-to-speech with Piper
• 🤚 Hands: Playwright navigates, clicks and fills in the fields
• 🔵 State orb: like Siri or Alexa, it shows the user what the agent is doing: listening, thinking or speaking

Platform design: one generic core plus interchangeable domain modules. The videos show the same core running two different kinds of software: a demo medical appointment portal and a 3D campus navigation map.

Design choice: I wrote the orchestration myself in Python, without LangChain or LangGraph, to keep full control of every step and of latency. No RAG: Asirea doesn't query documents, it executes actions in the software.
