I design and build software. I helped make products like Polychops, Matterway and Mindojo.
I organize meetups and conferences. I was involved in MoscowJS, Kaizen Berlin and Frontend Union Conf.

Hello 👋
Work
Polychops / Software for musicians
Polychops is a fun practice tool for musicians.
It’s a personal passion of mine. It started off with an idea for a polyrhythmic metronome and evolved into a drum machine and a looper that work in your web browser.
I’m still working on the app in my free time, doing research, ideation and implementation.
Polychops launched in September 2018.
Matterway / B2B SaaS
Making software at work usable.
With Matterway we developed a technology that allows customers to build ergonomic applications on top of their existing systems of record. Fast.
I joined the company early on and helped define and implement the product. By the time I left, Matterway had raised two rounds of funding and 30% of DAX companies were our customers or doing pilots with us.
Mindojo / EdTech
Mindojo is an adaptive e-learning platform.
The early version of the product is a GMAT preparation app published by The Economist journal.
I joined the company as a full-stack developer and worked on the Artificial Intelligence learning platform.
