One of the main technical challenges was to automatically integrate the employee databases provided by each affiliated company, allowing users to simply enter their RFC (Federal Taxpayer Registry) to be identified within the platform. This required translating various formats of administrative data into a unified, reliable, and secure structure. We designed a flexible data ingestion system capable of recognizing and synchronizing personal information, gross and net monthly salaries, and other key parameters such as maximum loan amounts. Thanks to this integration, users can register without filling out lengthy forms or depending on manual processes.

Another significant challenge was designing an intuitive and functional backend for companies to manage loans and monitor the status of their employees within the system. It was essential that the administrative panel allow for monthly updates of employee rosters, define credit policies (such as maximum lending percentages or differentiated limits based on job position), and monitor the status of each loan in real time. We achieved this by building a clean, user-friendly admin platform designed for non-technical users, focused on easing decision-making and minimizing the company’s operational workload.

Lastly, a critical challenge was ensuring the legal and technological security of the lending process, particularly regarding the digital signing of contracts. Each user needed to accept the terms and electronically sign a contract before receiving any funds, in compliance with legal requirements from both the lending company and local regulations. To meet this need, we developed a robust authentication flow and a secure digital signature solution, fully integrated into the app, which formalizes the process without extra steps or external complications.

On the screen where the user selects how much they want to borrow, moving the slider will update the amount and automatically refresh the payment terms and dates. This way, the user can easily see if the conditions are suitable for their loan.

The slider will only move in predefined increments set in the company's documentation, and it will automatically switch between an advance or a loan, which are two products with different terms.
