I'm Lucas Sifoni, an independent developer since 2015, based in Cahors, in southwest France. Since 2018 I've worked mostly with Elixir and the BEAM. I created and run Alzo, a saas for architecture agencies.
I also run
Turing-Express, a
micro studio for custom software and consulting. I believe no company is too small to benefit from Elixir and the BEAM.
In addition to that, I am an amateur telescope builder and mirror/optics maker, and provide small-scale custom services at Chantepierre Optique.
