Serial Entrepreneurship

Keiko

Keiko is a decentralized educational social network, conceived in 2019 and programmed as a DApp (blockchain-based application), which will allow everyone to have a Life Learning Passport based on unforgeable micro-credentials registered on the blockchain (Polkadot or Starknet), rendering traditional university degrees and certifications obsolete.

This network will allow students, tutors, and educational content curators to connect with each other through a mobile app that not only provides access to this Life Learning Passport, but also integrates:- AI for self-study guides
- Geographic search for tutors and co-working spaces
- A two-way grading system

I am currently designing a 4-layer microservices architecture, using different technologies such as Flutter, Dart, Widgetbook, GraphQL, gRPC, Starknet/Cairo, Polkadot/Substrate, Redis Streams, REST API webhooks, among others.

Vertivo

I’m CTO & co-founder of Vertivo.
We're an urban vertical farming startup incubated as Bridge for Billions alumni in 2021, dedicated to manufacturing and remote managing fleets of
Autonomous Urban Aeroponic Indoor MicroGreenhouses
to bring pesticide-free and decentralized
vertical horticulture to families, businesses, and industries in cities throughout Latin America.
In 2022 we raised a pre-seed round of US $9.500 thanks to Auge-UCR. Currently in Research & Development.

In 2022, we were selected to participate in the Road to Innovate Central America business incubation challenge, launched by the Friedrich Naumann Foundation for Freedom. We were selected among the finalists as an “Honorable Mention,” competing in Guatemala City.

We are currently recruiting volunteers who want to gain work experience through our startup (NOT internships).
