GraphQL

A query language for your API, and a server-side runtime for executing queries by using a type system you define for your data.

GraphQL provides a more efficient, powerful, and flexible alternative to REST, allowing clients to request exactly the data they need.

It is widely used in modern web applications for its ability to streamline data fetching and improve performance.

Experience:

Implemented GraphQL in ChainGraph for real-time blockchain data querying and subscriptions.

Utilized GraphQL in EOS Costa Rica and BitcashBank for API development.

Masterbots

Masterbots.ai is a platform that aims to elevate AI beyond ChatGPT by providing specialized chatbots, social sharing features, and user-friendly innovation. It features domain-specific AI chatbots that can perform more advanced tasks beyond basic information lookup or simple conversations.

RareMint

RareMint digitizes authenticated real-world sports collectibles as NFTs on the Polygon network, offering fractional ownership and trading of high-value items. The platform partners with professional sports organizations to ensure authenticity. I led technical efforts at RareMint to enhance the NFT marketplace's performance and maintainability, including the integration with Polygon network for efficient NFT auctions.

bitcashBank

Bitcash is an established crypto banking platform with over 50,000 users across Latin America, handling millions in transaction volume through its regulated financial infrastructure. 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.

ChainGraph

This real-time GraphQL toolkit is designed for EOSIO/Antelope blockchain applications, offering features like data subscriptions and querying multiple blockchains. As a personal side project during my time at Bitcash, I was responsible for the architectural design, technology selection, and coding of the toolkit, including a real-time blockchain data streaming package.

EOS Costa Rica

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.

EOS Rate

EOS Rate is a community-driven tool for rating EOS Block Producers, featuring a radial graph and community input stored on the blockchain. In this project, I was responsible for the technical architecture and selecting the appropriate technology.

Knowledge.io

Knowledge.io was one of the first blockchain platforms aimed at knowledge-sharing with a token-based reward system. The project successfully completed its ICO in 2018, raising funds to build a decentralized knowledge ecosystem that included partnerships with advertising networks to monetize user expertise. My role at Knowledge included leading the architecture of the Ethereum-based token and supporting systems for their successful ICO, and forming a skilled development team across three countries.
