Hello. Good afternoon.
I’m a Senior Product Designer at PayPal in Chicago.

Portfolio Work of Marko Masnjak

I believe interfaces should enable users to do a thing easier, faster, and better than otherwise possible. At the same time, that interface should bring order to the complexity through exceptional clarity, simplicity, and aesthetic. Anything more is a distraction.

Tip: Gratuity Calculator
Personal Project

Tip: Gratuity Calculator

Designed and developed an iOS app to calculate service gratuity and split with friends. This tip calculator is the first app in a larger side-project that focuses on providing small, simple apps that are fun to use and enhance social interactions without distracting from them.

Unified Merchant Intake and Onboarding

Unified Merchant Intake and Onboarding

Collaborated with a cross-functional team, as the product design lead, to consolidate multiple product offerings that onboard merchants onto the Braintree platform. Together, we delivered a new config-driven data collection form, migrated email communication from Rails to SendGrid with a fresh visual design, unified multiple tech stacks, and underwriting processes — for 42 currently supported countries.

Drop-In Mobile Payment Interface

Drop-In Mobile Payment Interface

Led product design for a ground-up redesign of Braintree's Drop-In UI for iOS and Android. Working with a cross-functional team, we delivered a new, fully customizable, experience agnostic version that allows merchants to control which components to use, and how they should look. We also included new international payment methods, Apple Pay, Google Pay, card scanning, and support for 23 languages.

Chicago Poster

I was commissioned by The Society of Typographic Arts to design a poster that embodied the essence of Chicago. My design along with other original pieces of art were auctioned off to support the Jack Weiss Student Scholarship Fund.

I am native to Chicago’s south side, where tavern-style pizza reigns supreme, and live in the Beverly neighborhood.

At PayPal, I work on initiatives for the Braintree Merchant Organization that often bridge multiple products in the PayPal portfolio. I collaborate with Engineering and Product Management Leads to discover, conceptualize, and prototype new experiences that enable best-of-class payment solutions for a global merchant base.

In my spare time, I moonlight as a father, husband, dog lover, snow sculptor, and weekend coffee enthusiast.

About Me

Through my 15-year career as a designer, my area of expertise has evolved to designing digital product experiences for browsers, iOS, and Android.

I began my career in 2004, practicing traditional graphic design. A few years later, my background in computer science and technical writing began to pull me towards designing brochure websites, email campaigns, and other digital content. Eventually, my focus pivoted to web and native mobile apps. I’m happy to say that I haven’t looked back.

Before PayPal, I was a Product Design Lead for dscout and Zendesk Sell (formerly Base) during large growth periods for each company. Before that, I helped newly funded startups get their MVPs to market at Doejo, and designed print and digital things for Crate&Barrel, JAK Graphic Design, and freelance projects.

My leadership style is personally casual yet professionally earnest with a “whatever it takes” attitude. I am known for tight collaboration on teams I work with, bridging design, engineering, and business priorities to deliver delightful end-to-end experiences to the customer. I am inspired by Swiss and Scandinavian design and look for new ways to bring highly functional, simple, aesthetic experiences into my work.

I also experiment with app ideas on the side. One app is a simple tip calculator currently on the App Store, and another is in the works.
