Grisha Kostyuk, experienced python developer

naspeh[at]gmail.com | 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. I usually choose fewer abstractions to be closer to the lower layer.

I love open source. In my spare time, I enjoy pursuing perfection on my open source projects:

  • Mailur – a lightweight webmail inspired by Gmail
  • Timefor – a command-line time tracker (my first recent dive into 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;
  • Golang recently.
