How do we know there is someone on the other side?
A single question, answered from two opposite directions.
From the outsideAt Hummand, I build infrastructure to verify humanity: liveness in the age of deepfakes, proof of personhood, verifiable identity and delegation for AI agents. The technical side of the question: proving there is a real person on the other side of the screen.
From the insideAs a researcher, I study machine consciousness, cognition, and AI welfare. The philosophical side of the same question: whether there is, in fact, someone inside the system.
What I build
- Hummand. Digital identity and proof of humanity as infrastructure: presence and identity proofing with an auditable record, in production; proof of personhood and AI-agent identity as a research track. Infrastructure for regulated sectors.
- The Alert. Uptime monitoring and observability platform: monitors, cascading alerts, status pages, and service dependency mapping.
- Nameplate. Public platform for monitoring and forecasting renewable energy curtailment in Northeast Brazil: a live counter of wasted energy, 24–72h forecasts, and public accuracy backtesting, built on open data from ONS, Brazil's grid operator. An independent project, developed by students at ECIT Henrique Fernandes de Farias under my mentorship as advising teacher.
- Canal Zero. An anonymous channel for reporting school violence, with a hierarchical dashboard aligned with the structure of Paraíba's Regional Education Offices. Requested by the Regional Office and developed by students under my guidance as a teacher, to give a voice to students facing bullying and other forms of violence.

A Spectrum, Not a Switchconsciousness
A 2022 intuition about consciousness as a functional spectrum, revisited through integrated information theory, Minsky's Society of Mind, and recent research on AI and welfare.
Now
What I want to highlight right now, for whoever's passing through.
