People I’ve worked with
What they say
„Sebastian has a rare ability to zoom out and see the whole product ecosystem, then zoom in and nail every micro-interaction. Working with him elevated our entire design culture.”
„I trust our way of working enough to hand Sebastian even high-risk challenges, step away to tackle other priorities, and return to find them not only resolved — but improved.”
„Sebastian fulfils all the tasks assigned to him, is punctual and proactive. He has highly developed communication skills. He actively seeks optimisation.”
„I’ve collaborated with many designers — Sebastian is the one who truly understands that great design is invisible. Our user retention improved significantly after his involvement.”
„Without your commitment, many projects would not have been completed.”
