Research → Product

How research shapes what I build. Every note is labeled so evidence, hypotheses and startup experiments stay separate.

  • Evidence

    Trust in shared data

    Published work (2018–2020) on blockchain-based access control for plant phenotyping and computer-aided diagnosis, and on suspicious transactions in IoT smart spaces.

  • Hypothesis

    Goals can become work orders

    Many needs can be broken into work orders that AI agents, people or both can execute and verify.

  • Experiment

    Chaucheros

    The product where I test that hypothesis. What I learn from it is a startup learning, not a research finding.
