about me

Short version:

I'm a software engineer, a doctor in mathematical logic, and I'm greek chilean, thus the two first names and two last names. I've taught a lot, and I've worked on set theory, medical statistics, formal proving (maths), graphing software, frontends and backends, search engines, container software, and networking software, among other smaller projects. Currently I'm very enthusiastic about lambda calculus and about compilers, a truly applied logic part of programming.

In some more detail:

My favourite languages, vaguely ordered: Common Lisp, Scheme, R, OCaml, APL (yes, APL), Python, Haskell, Shell (love and hate), and as a logician of course lambda calculus (untyped as a set theorist and typed as a formalist).

I speak four human languages: Greek, English, German, Spanish, and I can still understand some Dutch.

software projects

An incomplete list of my software projects. For my logic and for my statistics projects see publications.

lambda

A toy compiler of the untyped lambda calculus into common lisp (so far), written in common lisp, with an interpreter and a user interface (UI). The UI includes two REPLs and a viewer of all available transformations, or representations, of a user-input λ term. Showcases representations of lambda terms in my quest to understand compilers.

cgraph.inters.co

A diagram maker for relationships between certain axioms of set theory.

asd-graph

Dependency grapher for Common Lisp projects.

nbg-hol

Group project:
With the mathematical logic group of Bonn, that is Prof. Koepke and 11 bachelors and masters students doing a formal mathematics internship, we did a formalisation of von Neumann-Bernays-Gödel Set Theory of classes in Isabelle.
