Hi, I'm Edgar

👋

Software Developer and Math Enthusiast

TypeScript developer with knowledge of discrete algorithms and design patterns. In 2023, I launched ts-tonnetz, a package for algorithmic composition now used by Topos (try it here!).

Passionate about mathematics, I authored a Scopus-indexed article and developed the libraries fignumbers and figurate_numbers, the latter having over 2500 downloads.

In addition to teaching at the postgraduate level, I collaborate on international open-source software projects.

Projects

Topos.live | TypeScript
ts-tonnetz in the new live coding environment Topos!

Since December 2023, my library 'ts-tonnetz' is part of the Topos live coding environment created by Raphaël Forment and Miika Alonen. It serves as a dependency for Ziffers, a numerical notation system. For your convenience, I wrote documentation that synthesizes two PhD theses on mathematical music theory and other key research.

RubyGems | Ruby
Ruby module to generate infinite sequences of figurate numbers

This Ruby gem enables the generation of 241 infinite sequences of plane, spatial, and multidimensional figurate numbers. It is designed for use in your math projects or with Sonic Pi. Based on the book "Figurate Numbers" (2012) by Elena Deza and Michel Deza.

Figurate numbers in npm

Fignumbers is a comprehensive TypeScript library for generating and exploring infinite figurate number sequences, linked to geometric shapes across multiple dimensions. Based on the book "Figurate Numbers" (2012) by Elena Deza and Michel Deza.
