Georgios V. Pitsiladis

(he/him)

PhD in Mathematical Logic in Computer Science, with research on formal methods, formalised mathematics, and other applications of logic.
Interested in all aspects of software, from day-to-day coding (as type-safely as possible) to abstract logical and mathematical reasoning.
Passionate about free (as in freedom) software.
