Project Summary

A fintech startup hired Houlak to develop three mobile applications (iOS and Android) to enable credit-card and installment payments. Since relaunch, the product has processed significant transactions and expanded to more than ten clients and businesses locally, and the team is working on regional launches. The client praised Houlak's adaptability, timely delivery, and the product's ease of use, which reduced support needs.

Key Challenges

  • Startup pivot required an app that could adapt during pre-production changes
  • Need to ensure the app could support future payment methods and integrations without issues

Project Deliverables

  • Three mobile applications (one for businesses, two for clients)
  • Installment payment functionality and credit-card payment integration
  • QR code payment flow for client-to-business payments
  • Full mobile development for iOS and Android with ongoing adjustments

Project Solution

Houlak built three native mobile applications (iOS and Android) from scratch, implementing installment-payment support and a QR-code-based payment flow. They handled ongoing adjustments and integrations, implementing credit-card payment entry and merchant acceptance flows. The team used Swift and Kotlin and managed the project with a project manager and a cross-functional Slack group of ~17 people.

Project Outcome

  • Processed about $15,000 in the first month after relaunch
  • Processed $250,000 in April and expanded to more than 10 clients and businesses in Uruguay
  • Product placement in stores with low customer support requirements
  • Positive client feedback on adaptability, agility, and on-time delivery
