Work Experience

Self-employed at BYPASSS Kajetan Stasiura
December 2, 2025 - Present
Bypasss is a creative audio studio based in Katowice, Poland, built by artists, for artists. We offer music production, mixing & mastering, sound design, and full event audio production — but more than a list of services, we are a creative partner. Every project that comes through our doors is treated as a collaboration. We don't see ourselves as a service provider you hire and forget. We see ourselves as another artist in the room — one who happens to specialise in making your sound exactly what it needs to be. At the core of everything we do is a simple belief: art is the point. Not deadlines, not deliverables, not ticking boxes. We live for the moment a track locks in, when the mix breathes the way it should, when a sound design element hits and you feel it before you understand why. That obsession with the craft is what we bring to every session, every revision, every conversation. Our background is rooted in the internet music underground — hyperpop, digicore, cloud rap, experimental EDM. We don't just work in these genres technically, we come from them. That means we understand the aesthetic, the emotion, the references — and we can translate that sensibility across styles while keeping your sound coherent and distinctly yours. Over the years we've had the privilege of working with artists and creatives including Indecorum, Luvcrvsh, Parent Companyy, DJMegan23, XO, Blue Rojo, Kydekoi and more — across music production, mixing, mastering and live events. Each collaboration has been different. Each one has pushed us further. Beyond the studio, we produce and curate events that bring together electronic music, visual art, and spatial sound design — creating experiences where the audio and the atmosphere are inseparable.
Professional traineeship - Sound Engineer at KosaBuenaStudio
June 1, 2023 - August 31, 2023
During my time at Kosa Buena Studio — a professional recording studio specialising in recording, mixing and mastering — I gained hands-on experience across every stage of the audio production chain, from the moment a microphone is placed to the final master. My responsibilities covered a wide range of tasks. I was in charge of microphone preparation and placement before each session — selecting the right mic for the source, positioning it correctly, and ensuring everything was ready before the artist walked in. Working with Pro Tools as the primary DAW, I managed session setup, recording workflows, and maintained clean, organised project structures throughout every session. Beyond the studio itself, I assisted on location recordings outside the controlled environment — including sessions held at the orchestra hall at the Academy of Music in Katowice. These experiences taught me how to adapt quickly, work with complex multi-source setups, and maintain professional standards in unpredictable acoustic environments. I was also responsible for maintaining the studio itself — keeping the space organised, preserving proper signal flow at all times, and ensuring that all hardware and cabling was correctly connected and functioning. Understanding signal flow at a deep level became second nature: from microphone to preamp, through the interface, into the DAW, and back out through monitoring — every link in the chain matters. On the technical side, my time at Kosa Buena gave me a thorough grounding in the full mixing and mastering process. I learned how the quality of a mix is determined long before you open a plugin — it starts with microphone technique, the choice of mic and preamp for a given source, room acoustics, and clean gain staging from the very first step. I deepened my understanding of hardware integration, outboard gear, and how analogue and digital elements interact in a professional signal chain.

    Djmegan23, Blue rojo - lo siento

    This collaboration between DJMegan23 and Blue Rojo arrived at bypasss.com for mastering in December 2024, and my role was to take what they’d built in the studio and translate it into a mix that could translate consistently across all listening environments — clubs, headphones, mobile devices, streaming platforms, the full spectrum.
    The track came in with a lot of energy and character already in place. What mastering required here was careful balancing: bringing clarity to the mid and high-frequency elements without losing the punch and low-end weight that gives the track its impact. I ran the mix through transparent linear-phase EQ, subtle multiband compression to control any problematic resonances, and a clean limiter chain to maintain headroom while ensuring the master could compete with contemporary releases on the same platforms.
    The goal was to preserve the original production’s intent — that playful, high-energy aesthetic you can already hear in the track’s description — while ensuring it had the technical polish and consistency needed for distribution. Part of that work also involved checking the master across different reference systems to catch any translation issues before export.
    This was a straightforward but essential part of the pipeline: the mastering stage where a track moves from the studio context into the world. By April 2025, “LO SIENTO +BLUE ROJO” was ready.

    BOMBI HOOD - PARE ZDJĘĆ

    "

    The idea started with a simple but specific vision: take the DNA of early 2000s rap — Timbaland’s signature percussion, those stuttering hi-hats, the space and tension between kicks — and pull it somewhere darker. Not the polished, radio-ready version of that era. Something rawer, moodier, like that sound never made it out of the street.
    Production began with building the beat from scratch around that reference point. Every texture was chosen deliberately — keeping the rhythmic blueprint of the era intact while warping the atmosphere into something that felt genuinely cold and modern. The goal was a track that could have existed in 2003 but clearly didn’t.
    Recording sessions followed. Getting the vocal performance right was as important as the production — the delivery needed to carry the same weight as the instrumental. Multiple takes, fine-tuning in the booth until the voice sat inside the track, not just over it.
    The final layer was the visual. The music video was built to complete the world the record created — the framing, the colour grade, every aesthetic choice made to match the dark, stripped-back energy of the track.
    Start to finish: a fully collaborative project built around one idea — classic rap DNA, but colder.

    kydekoi - alther

    alther is a five-track EP that took shape over the course of roughly fourteen months — from August 2024 through October 2025 — and every single element of it, from the first sound design session to the final artwork, was handled entirely by me.
    The conceptual core of the project — a recollection of memories and feelings, all altered by the human mind, blurred and destroyed — dictated the production approach from day one. I wanted the sonic world of alther to feel inherently unstable, like recalling something you’re not sure actually happened the way you remember it. To achieve that, I leaned heavily into the aesthetics of daria core: its tendency to treat distortion, oversaturation, and tonal dissonance not as flaws but as emotional textures.
    A significant part of the early sessions was dedicated to intensive sound design work — building custom patches, layering heavily processed samples, and sculpting sounds that felt simultaneously familiar and wrong. A lot of source material came from old video game soundtracks and cartoon scores: sounds that carry a very specific childhood imprint, which I then ran through various chains of pitch warping, bitcrushing, granular processing, and re-sampling until they became something unrecognisable yet emotionally loaded. That contrast — between something nostalgic at its root and something distorted and destabilising on the surface — was exactly the kind of psychological friction I was going for.

    Beyond the music itself, I was also responsible for the visual identity of the release — cover art, overall aesthetic direction, everything. The goal was to keep the visual language consistent with the sonic one: something that feels like a glitched memory rather than a clean image.
    alther was a fully self-contained project in every sense — produced, recorded, mixed, mastered, designed, and performed entirely by me, under the kydekoi name.
