Fullstack JS / TS Developer, Medpoint24, 2017 - 2020

The company is engaged in automation of medical examinations. Users are

   examined using the company's automated complex, the data is sent to the

   server, processed by a medic who decides whether to allow or not to allow a

   person to work.

   I created and supported (first alone, later in a team, supervising other

   developers):

   - desktop-application for medical examination (terminal) (wilton, sqlite, Node js,

   Vue js, Typescript, webpack) (main part of company services);

   - desktop-application for medics who process these remote examinations

   (wilton, sqlite, Node js, Vue js, Javascript);

   - microservices on the server (file generation, electronic signature) (wilton,

   Javascript).

   I took an active part (from the idea, the formulation of the technical

   specification to the direct implementation) in the team development of the

   terminal management service, their auto-updating and remote editing of

   settings (Nodejs, Typescript, Nestjs, Postgres).
