Hi, I'm Maciej.

Experienced Machine Learning practitioner, combining research background with a strong grasp of software engineering and the web.

I led AI efforts at RainforestQA, where we built world's best no-code test automation (I might be biased), generative-AI based test case generation and novel image matching models among other things. I also act as an adviser in the field of AI and ML. You can hire me.

Previously, I was a co-founder & the CTO of Teacherspace, where I built the web app as well as the iOS and Android mobiles apps from scratch. Ask me about how fun it is to correctly implement sensitive video storage relying solely on European cloud providers!

Previously previously, I worked as a Computer Vision Engineer in the eye-tracking domain and completed a PhD in ML & Computer Vision at UCL. I also ran my boutique web design & development agency in the more distant past.
