A little bit about myself
Scenario
What is ?
We integrate private, public and co-operative banks
2020
Is the first tech solution in argentina that integrates all banks
in a single app
HOW TO DESIGN A SOLUTION
a.k.a. what we initially did
Use cases to implement
Onboard users to the platform
Send & receive money to & from friends
Pay with a QR code in a shop
. . .
We used open api and swagger as the common place for our api ecosystem docs
Swagger + OPEN API
Swagger is an open source software framework backed by a broad ecosystem of tools that helps developers design, build, document, standardize and consume RESTful Web services.
The OpenAPI Specification, originally known as the Swagger Specification, is a specification for machine-readable interface files for describing, producing, consuming, and visualizing RESTful web services.

Something wrong or missing? Break everything!
#1
INTEGRATE AS SOON AS POSIBLE
#2
With this in place, we released on december 2020 🎉
ecosystem v1.0
we are GA, now what?
Is the first tech solution in argentina that integrates all banks
in a single platform
Top-d0wn approaches are great for the beginning, but harder to maintain
No breaking changes
3 versions of the api
similar to what node.js does
BETTER COMMUNICATION
OPEN & BIDIRECTIONAL
and automated (as possible)
DOGFOODING
Test our stuff
puting on the client's hat (and reducing friction between teams)
we are today building the foundation of a live ecosystem, evolving together
ecosystem
PLANNED EVOLUTION
Solid foundations
key stakeholders as feature champions (beta testers)
#1
newsletters: from emails to reduced audiences to all
#2
improved ecosystem: notifications via events
#3
public roadmap & organize work with initiatives/themes
#4
We don't have all the answers, but for sure it's going to be a great ride
Thanks!
