fairTools: Group Decision Platform Using Median Voting

FairTools is a set of tools to make collaborative technologies accessible to anyone and consists of:
• A text editor (fairPad)
• An immutable repository (fairStore)
• A document broadcast network (fairNet)
• A network registration tool (fairFriends)

Self Health Quantification Blockchain

Self Health Quantification BlockChain is a distributed personal health record (PHR) that is private and secured with the help of blockRing technology.

I developed a set of tools to capture, in a non-invasive way, the health status of volunteers. Once captured, the non-private data is placed in an observable open data lake for deep machine learning.

Crypto Seed Accountancy Platform

I developed a system that uses cryptocurrencies in order to create value in an early-stage project.

The system is designed to use either a calendar or a venture capitalist's (VC) release timeline.

Web and Graphic Design

Developed simple low footprint websites as well as business-ready sites using fast and static HTML combined with light dynamic functionality (JAMStack).

This allows for platform-agnostic deployment at any provider, including hostless solutions.
