About me

  I'm a curious spirit with a diverse range of interests. However, first and foremost, I'm an artist - a music composer to be more precise. My adventure with digital audio processing began in 2019, with creation of my one-man band Templum Somnia. I choose to call it "a band" despite being its sole member in order to disconnect my artistic endeavours from the person I am on a day to day basis and to emphasize my desire to include other like-minded people in this project.
  The music that I create is heavily influenced by the work of Chris Corner (of IAMX and Sneaker Pimps), Lauren Bousfield (Nero's Day at Disneyland) and Grzegorz Ciechowski (Obywatel G.C, Republika). I also draw a great deal of inspiration from Radiohead, Muse, Sergei Rachmaninoff, The Cure, Joy Division, Depeche Mode and other musical geniuses that came before me. Even though I stand on the shoulders of giants, I like to think I manage to put into my songs enough of my own ingenuity to make them feel truly unique and unmistakably mine.

  At the beginning of 2026, after a couple of months of internship I was offered to become a full-fledged member of Anaesthetic. I took them up on that offer. I am now responsible for the audio presentation in our debut title, Unwell.

  I study IT with the focus on video game development at DSW University of Lower Silesia. If plans don't change, I'll be defending my bachelor's thesis in the first quarter of 2027.

My projects

  Below is the collection of major projects that has seen my involvement. I look forward to expanding this list in the near future.

Templum Somnia

"Gift my life its purpose. Something divine, Something new"

  Genre-defying, one-man band whose distorted, electronic tones comfort the disturbed and disturb the comfortable.
  So far, Templum Somnia has published three albums, with a fourth currently in production.

  I'm a sole mind behind this project and unless stated otherwise, I handle every element of production by myself.
  Alitaba is an honorary team member, though her involvement is limited to assistance with graphic design.

Give it a listen on:

Bandcamp hosts only songs which made it into an album. As for now some songs may be accessible only via Youtube.

Anaesthetic - Unwell

"Stand with us against The Gray."

  Unwell is a terrifying, psychological survival horror inspired by dr Freud and dr Hawkins works. Sneak among the whispers, fight monsters from the past, solve puzzles that reopen old wounds, and explore the corridors of your own mind—before what you repress becomes your only guide down the well.

Steam Description

  Following a couple of months of internship I was welcomed as a core member of a polish indie game-dev studio, Anaesthetic.
  We're in the process of working on our debut title, Unwell.
  I'm co-responsible for the audio side of the game. My duties include both creation of assets (SFX and music) and their implementaion via FMOD.
