UIN

Engagement for any product.

01. Overview

UIN is a B2B platform that allows fintechs and financial institutions to integrate gamification mechanics, missions, rewards, digital goods, directly into their products, without building the infrastructure themselves.

I was the designer responsible for the full product: UX strategy, backoffice flows, end-user screens, and direct collaboration with the product, front-end, and back-end teams.

Role: Sr. UX/UI Designer

Platform: B2B SaaS, white-label

Methods: Design Thinking, Agile, Lean UX

Tools: Figma, Jira, Notion, v0

02. Problem

While working on n1u, a fintech wallet built for gamers, something became clear: users responded to reward logic and gaming visual language in ways traditional financial products couldn't replicate. But building that experience by hand inside each product doesn't scale.

What if any fintech could offer that experience without developing it from scratch?

That created a design problem with two simultaneous, opposing fronts: the admin needs an operational tool, fast, frictionless, no code. The end-user needs an experience that feels like gaming, not banking. Neither can be sacrificed for the other.

03. Design Process

The first input was everything learned from n1u: what hooked users, what confused them, what someone from the gaming world expects when interacting with a financial app.

I benchmarked references like Nubank, Mercado Puntos, and B2B engagement platforms to understand which mechanics had real traction, not just visually, but functionally.

I mapped both user journeys separately because their logic is fundamentally different. The admin: create, configure, publish, monitor. The end-user: discover, participate, earn, redeem. Decoupled technically, cohesive in experience.

I worked in short cycles with the team: lo-fi to align flows with product, internal validation, hi-fi in parallel with dev. Documented specs in Confluence to reduce dependency on constant back-and-forth conversations.

Design Philosophy

Whether you're designing the system behind the scenes or the experience users actually feel, both have to be fluid and intuitive.

04. Solution & Results

I designed the full product across three layers:

Mission Builder, a step-by-step flow where admins define the trigger action, choose the reward, configure conditions, and publish. No code, no dev dependency for every change.

Inventory + Bundles, digital goods management (skins, tokens, vouchers) with stock rules, and a bundle system to combine rewards into a single package. Simplifies the admin's operation while enriching what the end-user sees and receives.

End-user screens, active missions, visible progress, reachable reward. Gaming visual language inside a financial context.

The entire system designed as white-label: each client customizes their identity without touching the core.
