Grisha Kostyuk, experienced python developer

naspeh[at] | Yaremche, Ukraine | remote only

I'm a passionate python developer with over a decade of experience in web development. I'm especially strong in back-end development, good in automation and deployment (including CI/CD). Occasionally, I can do modern front-end.

I love simplicity, so I usually try to simplify things.

In my spare time, I enjoy working on my open source projects, pursuing perfection, learning, experimenting:

  • Mailur – lightweight webmail inspired by Gmail
  • Timefor – a command-line time tracker (Golang)
  • more projects on github page.

Technologies I've been actively using:

  • Python since Oct 2009;
  • PostgreSQL and Redis since Mar 2012;
  • Git since Dec 2009;
  • Linux since Jul 2008;
  • Containers since Aug 2014 (podman, docker, lxc, systemd-nspawn);
  • Bash, JavaScript, CSS/HTML periodically for many years.
