Deubom

Context & problem

DeuBom was created to help local businesses bring customers back to physical stores after the pandemic, with a simple way to promote real-time deals and boost visibility.

• Empty stores after the pandemic — Local businesses struggled to bring customers back to physical stores.
• No affordable visibility — Small merchants lacked simple, affordable channels to promote their offers.
• Inventory going to waste — Without a fast way to advertise deals, perishable stock was thrown away.

Results

The DeuBom app helped small businesses attract more customers and increase revenue, with a seamless way to promote real-time deals.

• 20% Revenue — Growth for Partners
• 60% Repeat — Purchase Rate
• BRL 200K — in Angel Investment
• 50% Less — Inventory Waste

Goals

• Increase Customer Traffic to Local Stores — Help small businesses attract more customers by promoting nearby deals and enhancing their store presence.
• Encourage Local Shopping — Strengthen the connection between consumers and neighborhood businesses, making it easier for people to find relevant promotions in their area.
• Ensure an Intuitive User Experience — Design a user-friendly platform that allows both merchants and customers to engage effortlessly, driving adoption and retention.

Process & discovery

I performed qualitative and quantitative user research, developed personas, and designed low and high-fidelity prototypes for both web and mobile. Additionally, I carried out usability testing and created MVPs to quickly validate the solution with users and investors. I also worked full stack, building the app in Flutter, the web version in React and the Node.js backend with PostgreSQL for deals and cashback.

• Research — Qualitative and quantitative research with merchants and shoppers.
• Personas — Merchant and shopper personas to guide every decision.
• Prototype — Low and high-fidelity prototypes for web and mobile.
• Validate — Usability tests and MVPs validated with users and investors.

Tools

Design and code in one flow: from UX/UI in Figma to the frontend and backend in production.

• Figma — UX/UI & Prototypes
• Flutter / Dart — Mobile App
• React — Web App
• Node.js — Backend & APIs
• PostgreSQL — Database

Learnings

• Validate before you build — Testing the MVP with users, partners and investors de-risked every decision.
• Local businesses need simplicity — Merchants had little time, so creating a deal had to take seconds.
• Design can raise money — A clear product story and prototype helped secure the first investment.
