Medior Python Developer


  • You see yourself as a solution crafter. You like to bend your mind to not only find the answer to a riddle, but also the most elegant.
  • You like to be under pressure from time to time, let’s say when the time is short and the stakes are high. But you also appreciate to be given time to think and perfect your skills when nothing is on fire.
  • You don’t like to feel like a big fish in a small pond, and want to learn and grow your skills continuously.
  • You wish there was a place that would respect who you are and support you and your quirks, rather than turn you into a “presentable” cog.
  • You care about others, and want your work to profit not only you, but cascade back to the community.
  • You sometimes go to bed with your brain firing all cylinders on a problem to crack, only to wake up in the middle of the night screaming “eureka” (unless it’s under your shower the next day).
  • You take pride in your skills, and enjoy sharing your experiences with others.
  • You are accountable and dependable, and you never take things for granted.
