Challenge
A restaurant network operating across multiple locations in Guatemala came to us with a need to elevate their service through a stable, smoothly functioning mobile and web platform. We undertook a custom project involving three interconnected applications: one for customers, another for delivery personnel, and a third administrative app for admins, staff managers, call centers, and restaurant service quality control. The client provided detailed app functionality and ready-to-use UX/UI design with a strict requirement to follow the existing design without any changes. The core business challenges were significant. The client needed seamless integration with Cybersource payment gateway via VisaNet — a complex technological solution requiring intricate work with limited documentation for Node.js REST API. We also needed to integrate with InFile (NIT), a Guatemalan service for invoice subscription that required processing massive amounts of documentation and responses in Spanish, with complex data requirements on what data should be entered in CSV documents and requested content. Additional challenges included working with Strapi CMS (version 3.6.6), which lacked flexibility — many microservices and plugins like socket.io, SendGrid, and auth providers had reduced functionality. Database handling was complex, with standard methods unable to handle complex aggregation queries, and bugs in deep filtering using the count method. The call center functionality required blending extensive functionality on a single page. The client had previously struggled with fragmented solutions and needed a partner who could bring technical clarity and structured delivery to a complex, integration-heavy initiative.

Solution
We started with discovery and technical analysis to understand all integration requirements before any development began — ensuring clarity and reducing delivery risk. We designed and built a comprehensive ecosystem with three interconnected applications, each tailored to specific user needs. For customers, we developed mobile applications for iOS and Android with built-in GPS powered by Google Maps to monitor delivery time, in-app calls to client or call-center, customized data picker, and in-app translation from English to Spanish and back. For delivery personnel, we built a mobile app with order confirmation, navigation, and delivery status updates. For admins, staff managers, and call centers, we developed a web admin panel with role-based access — Admin panel, Call center, Store manager. The call center interface blended extensive functionality on one page: user search, delivery address creation and management, driver route tracking, order distribution and processing, daily menu updates, shopping cart with multiple filters and product categories, and cash/card payment preference. Technical innovations included integration with InFile (NIT) — we translated documentation into English, sent multiple test requests, analyzed responses, and used a cut-and-try approach to find the right implementation. For Cybersource payment integration with limited documentation, we conducted self-education, aggregating different code examples into a single working solution. For Strapi CMS challenges, we reworked and modified components and modules, creating custom database queries via knex.js using MySQL syntax. The architecture was designed for multi-location scalability — supporting more venues, more users, and higher order volumes without costly rebuilds. Our AI-accelerated senior engineering approach enabled faster prototyping and automated testing — while all architecture, quality, and technical decisions remained under senior control. Structured delivery with dedicated PM and QA ensured transparent communication, predictable milestones, and clean execution from discovery to release, completing the project in 7 months.

Results
The new ecosystem transformed the restaurant network's operations, delivering measurable improvements in order processing, delivery coordination, and customer engagement. We added several key features for both the mobile app and web platform to create the best restaurant delivery software and make the user experience pure bliss. The platform became widely embraced in the region due to its convenience, resulting in a surge in consumer interest. Sales and customer loyalty experienced significant growth, and the app contributed to the creation of new job opportunities for couriers and administrative personnel. Key outcomes included seamless integration with Cybersource payment gateway enabling secure transactions; successful integration with InFile (NIT) for compliant tax invoice processing; centralized administration with role-based access for admins, call centers, and store managers; real-time GPS tracking for delivery monitoring and route optimisation; and multilingual support enabling seamless customer experience. The platform now serves as the backbone for the restaurant network's digital operations, enabling continued growth with predictable delivery, clear documentation, and a healthy vendor-independent ownership model. The solution helped streamline order processing, improve delivery coordination, strengthen customer retention, and simplify operational management across multiple business units and locations.
