Technical Fluency

I understand code. Engineers get buildable specs, and edge cases get caught before sprint, not after launch.

Customer Obsession Measured

Research-driven design tied to business metrics. If customers don't feel it, it didn't ship.

Hi! I'm Renny o/

Renny Murakami

I've been in product design for 7 years now, and my path wasn't a straight line.

I actually started in gaming, I studied digital game design, and that's where I fell in love with UX, figuring out how to make a player understand a game's mechanics without a single line of instruction, was really fascinating. I was also a teacher for a while, and that taught me something that still shapes how I work: there's never just one way to explain something complex to the other person, you adapt until they get it. Those two experiences, games and teaching, are really where my whole approach to design comes from.

And a curiosity, the character for 'to work' literally means to make things easier for the other person, that idea has stuck with me my whole career.

Today I work as a Product Designer Specialist at Fiserv, in a strategic layer for LATAM, inside the culture and innovation pillar. I partner constantly with HR, Marketing, CX and the Executive Board, tracking satisfaction data and UX research to spot opportunities nobody's formalized yet.

The best example is a customer referral program I built from the ground up: no one asked for it, I connected CX data to an internal engagement initiative, piloted it internally first, and it now converts 13% of referrals versus the usual 2%, paying back its investment in four months.

I believe design only really works when you understand both people and business deeply enough to be trusted by both. That's why I bring hands-on design craft together with real commercial awareness, and early this year I was recognized as a Fiserv Ambassador for exactly that, putting the culture into practice and being someone the team trusts to unlock things internally as well.
