Case Study
Overview
We partnered with an innovative technology company specialized in Artificial Intelligence (AI) solutions to design and develop a comprehensive subscription management system and a robust integration ecosystem. The project spanned everything from building fluid front-end interfaces, to implementing back-end services, cloud deployment, and advanced synchronization with corporate CRM platforms.
The Challenge / Objective
Automating subscriptions, payments, and enterprise connectivity
The client needed to automate and efficiently manage their subscription model, payments, and plan selection directly from their web platform. Additionally, they required a scalable technical architecture capable of connecting their main AI product with external business ecosystems (such as Salesforce and HubSpot), while guaranteeing at the same time secure real-time data handling, high service availability, and a flawless user experience.
Case Study
Solutions Implemented
During the execution of the project, our engineering team carried out the following technical solutions:
Modern Frontend Development
Construction of a complete and interactive user interface in Angular for subscription management. This covered the development of dynamic portals, corporate team administration (seat control, member viewing, adding and canceling seats), and detailed plan presentation.
Payment Gateway Integration
Implementation of a secure checkout flow integrated with Stripe for automated payment processing. Complex webhooks were configured to guarantee real-time notifications about billing and completed transactions.
Scalable Backend Services
Development of robust APIs (using Node.js and Python) responsible for calculating dynamic pricing, validating account cancellation requests, managing corporate license allocation, and processing data through asynchronous flows.
Integration with CRM Ecosystems
Native connections with the CRM platforms used by the client's own B2B customers, keeping commercial data synchronized in real time.
Salesforce
Development and installation of a managed package with secure OAuth 2.0 authentication and webhooks for real-time bidirectional synchronization of statuses and customers.
HubSpot
Development of a microservice using a serverless architecture to keep the company's business flows centralized and synchronized.
Cloud Architecture & Infrastructure
Secure deployment of services using multiple automated environments on AWS, provisioned entirely through infrastructure as code (OpenTofu).
Hybrid Database Management
Implementation of a high-performance data model, using PostgreSQL as the relational database (source of truth) together with DynamoDB for agile transactional operations.
Case Study
Results & Impact
The result was a highly scalable and 100% automated software platform. The successful integration with Stripe allowed the client to process payments and manage their SaaS subscriptions without requiring manual intervention, drastically optimizing the adoption of their users.
In addition, the solid cloud-native infrastructure and direct integrations with leading systems such as Salesforce and HubSpot provided the company with enterprise-level operational capacity, facilitating fluid and secure data communication with their own B2B clients.
