Working at Personio.com
I’ve been doing beginning-to-end Product Design for about 15 years and worked with companies like 37Signals, Booking.com and Remote to create experiences that matter and lead happy, fulfilled teams.
Case Studies
I’m all about helping teams envision their future and making it a reality. Still, much of my work remains under NDA. So I’ve handpicked two contrasting case studies that provide insights into my approach:
Working Together
Whether as part of an in-house team or hopping aboard as a freelancer, here’s what I bring to the table:
-
User needs advocacy with a balanced understanding of business value
-
Eagerness to think big while taking properly-sized steps
-
Clear and thoughtful communication, both synchronously and asynchronously
-
An organized approach to work with high standards
-
A purpose-driven leadership style
-
Mentorship as the cornerstone of my professional legacy
I’m currently working as a Principal Product Designer at Personio! But if you wanna talk about design, music or life, drop me a line at hi@tassia.eu and I’ll respond soon.
About Me
My journey began as a web designer at a prominent news agency in Brazil before transitioning into academia as a professor in the design department of the Federal University of Bahia. In 2014 I ventured to The Netherlands to join Booking.com, where I grew into the role of Lead Designer. There, I designed complex internal applications for the Customer Service department—one of the largest in the world. I then delved into information architecture projects while embedded within the Design Systems team.
In 2021 I joined Basecamp (now 37Signals), contributing to the launch of HEY World, followed by Remote, where I worked on their flagship product. I made my way to their marketing team, which inspired me to get a Brand Specialist certification.
This journey has afforded me over a decade of experience in tech across Europe, Latin America, and the US with even more years immersed in the world of design.
Rooted in The Netherlands, I operate as a design interventionist and consultant, bringing my strategic and tactical expertise to teams of all sizes—from product discovery to front-end development.
Fun Stuff
Here are some projects I’ve poured my heart into, just for the sheer joy of it.
In 2012, I was fortunate to work with the incredible folks from the ukrainian band Odyn v Kanoe. I created their visual identity—at the time, they were about to release their first album, which I designed the cover of (alongside concert tickets, posters and other materials).
In 2023, I did some calligraphy work for the cover of their single Один в полі воїн.
Business cards and visual identity (with custom type design) for the photographer Paula Abrahão and the embroidery artist Giselle Quinto.
Abyssal is a simple theme from a type enthusiast (me) who was looking for modifications that would improve the reading and writing experience without dramatically changing Obsidian’s interface. Besides carefully selected colors, I created a type scale that influenced all the spacing. You can read more on the GitHub repository.
As someone who used to run tons of design-related workshops, especially Design Sprints, I constantly found myself providing visual examples of how some of these exercises worked, since it helped participants understand them better. I also struggled with timing… So, I created a deck with illustrations and actual animated timers that helps facilitators and attendees alike take the most out of the exercises.
This deck is now an official bonus for those who purchase the book and has been translated by the community into other languages.
