It features a batch auction system for token sales, ensuring fair and transparent price discovery.

The platform integrates with local banking systems in multiple countries and features BitcashDAO for community governance of its decentralized finance products. At Bitcash, my role from the start focused on infrastructure design, tech recruitment, and developer training. I later transitioned to a consulting role to guide the platform's continuous adaptation and success.

EOS Costa Rica is a leading block producer and infrastructure provider for EOSIO/Antelope blockchains, maintaining critical network nodes and developing custom blockchain solutions. The company is recognized for its contributions to the EOS mainnet and enterprise blockchain implementations. Joining EOS Costa Rica at its inception, I played a key role in the EOS mainnet launch, managed validators for multiple networks, and helped establish the custom development services division. My major contribution included leading the architecture for a custom private blockchain for Grant Thornton.



Wink

Wink, Costa Rica's first neo-bank, offers a mobile app for online banking, eliminating the need for physical branch visits. I developed the first version of Wink's mobile app and backend services within AWS. My role involved API integration with partner banks and forming a dedicated development team.

I was responsible for the frontend architecture design, integrating the game app with Facebook and the backoffice system with Brightcove web services for video streaming and editing.

Costa Rica JS, founded in 2010, grew to become Central America's largest JavaScript community with over 2000 developers. The community played a crucial role in fostering the region's tech ecosystem during the rise of Node.js, organizing major events like NodeSchool International Day and hosting speakers from companies like Mozilla and Netflix. As founder, I organized regular meetups, workshops, and the annual JSConf Costa Rica, helping establish Costa Rica as a growing tech hub in Latin America.

AsoBlockchain, founded in 2017, is Costa Rica's first and leading non-profit blockchain association. The organization has trained over 1000 developers, partnered with major universities like ULACIT and ADEN Business School, and played a key role in shaping national cryptocurrency regulations through collaboration with the Central Bank and other regulatory bodies. Through initiatives like TicoBlockchain conference and CriptoCantina, it has become the primary driver of blockchain adoption in Central America.
