What I do
Lesti Software is a one-person company run by Lev Stipakov. Client work: systems software, networking and security, and cross-platform native code — mostly OpenVPN, with room for the right additional engagement. It also builds and ships its own apps, such as Ehtii, an AI booking assistant for small businesses, StipaCaller and Kansalaisuuskoe.
