Stuff I do

Art direction

I build, mentor, and manage in-house and remote design teams tailored to each customer. Whether you're an enterprise or just a few friends building a start-up - I can help you create a winning design team from scratch or improve an existing one.

UX & UI Design

A sworn introvert, but always a team player, so beware of that misleading first impression. Hands-on designer, always ready for an exciting challenge. AI? Dashboards? Unconventional media? Mobile apps? I eat this stuff for breakfast, and I'm still craving for more.

Brand & Brand

If by "can you design me a logo," you mean brainstorming, research, strategy, and even "some" actual design and a design system if you wish, then yes. Seriously, I take branding very seriously... But sure, I do "logos" too 😉

And I can prove it, too

Working with Leonid was nothing short of awesome:
It's a rare trait to find designers who understand code and its mechanics yet Leonid has a vast background in both programming and implementing his designs for developers. Leonid's work and methodical understanding saved us tons of working hours and his vision of the web, in my opinion, helped to move us to the next level.
If given the chance, i'd love working with him again. really, give me a chance 🙂

Leonid was wonderful in designing our app for the Cricket device. Got the concept really fast and delivered an intuitive UX design that was better than what we've envisioned for our app. All of this was done super fast, with excellent communications, and on a budget.
Thanks Leonid!

It’s been a real pleasure working with Leonid: His design skills, combined with some extremely rare technical skills, have landed this delicate interface project, softly and surely on track and on time.
