Credit card machines experiences
Dandara \ Work
My career started in programming. I worked as a front-end developer for an HR Saas that offered an unified way of managing culture and well-being at companies. Although coding is a passion of mine, I felt the need to know more about our users and their needs, enough to find out Product Design was a better use of my skills.
That same year, with some free courses, books and some Scott H. Young energy, I studied Design. This happened in pandemic times while I also studied for Brazil uni entrance exam. Somehow it all worked out: I survived the pandemic, got a full-time role as Product Designer in one of Brazil more established design teams, made it to university with honors and even managed to get a design award while at it .
Unfortunetely, my stay at 5A was short due to a company reestructuration layoff. I left there with a good taste of how mature design teams operate and shortly after started at Stone. At Stone, I proppel and polish old and new applications on credit card machines.
This is a very niche opportunity of design and a very risky sector (finances and entreuperneuship). Consolidating my skills in this environment is likely the reason why I love complex and specific problems to which we can always find elegant, and, in retrospect, simple solutions.

“Before this, it was a tiring process to install apps for the clients.” - Stone Agent
On August 2023 Stone had +200 partners running software on its credit card machines. The flow to hire and install these partner apps was convoluted for both Stone agents and Stone clients (entrepeuneurs).
Why not bring the simplicity we already know of installing apps on our phones to these machines?
I conducted an internal discovery to delineate the risks and challenges of simplifying this flow, for example, how could this overload our internal teams? The result of this discovery was a rulebook for partners and testing teams.
I also developed the first proprietary app for the store, "Fichas" (Tickets), focused on making the machine usable in small events and not only day-to-day sales.
40% of Stone partner base was migrated to this new flow within the initial 6 months of launch. Today, this is the default flow for partners.
