Developing Core Revenue and Engagement Modules for a High-Scale HR Platform

As part of the development team for a US-based HR platform with over 70,000+ users, I developed and maintained multiple software modules to enhance user engagement, enable live certification programs, and integrate payments, all while working within the original platform's existing legacy tech stack.


🧭 Context: Scaling Engagement and Monetization

The HR platform was experiencing significant user adoption but lacked the core modules necessary to monetize advanced training and manage high-volume professional development events. The need was critical: to transition from a content-only platform to a comprehensive, interactive, and revenue-generating educational tool.


🎯 Objective: Feature Delivery and Revenue Enablement

The project focused on delivering three high-impact, integrated modules to support a growing professional user base.

  • Engagement: Develop robust Event and Program modules capable of managing thousands of registrations and live attendance simultaneously.
  • Monetization: Implement a reliable and secure Stripe payment gateway for both recurring subscriptions and one-time program enrollments.
  • Value Creation: Introduce a Live Certification feature to attract new professional subscribers and increase platform value.
  • Reliability: Ensure scalability and reliability for the existing 70,000+ users and anticipated growth.

⚙️ Solution: Feature Development on Existing Stack

I utilized the current Express.js, React, and PostgreSQL stack, focusing on clean, scalable API design to integrate complex business logic into the existing framework.

Key Technical & Functional Highlights:

  • Event Management Module: Built a full-cycle event creation and registration system, handling state management for RSVP, attendance tracking, and capacity limits.
  • Live Certification Module: Designed and implemented the logic for tracking user progress, verifying completion requirements, and automatically generating digital certificates upon successful program finish.
  • Robust Payment Integration: Seamlessly integrated Stripe to handle secure credit card processing for program enrollment and managing recurring billing for platform subscriptions.
  • High-Volume Data Layer: Structured PostgreSQL schema for efficient querying of user, event, and certification data to ensure quick load times, even with 70,000+ user profiles.
  • AWS Deployment Strategy: Managed scaling and deployment using AWS Elastic Beanstalk to ensure the backend could reliably handle sudden spikes in traffic during event launches and program sign-ups.

✨ Results & Impact: Driving Subscriptions and Revenue

The successful delivery of these core modules directly influenced platform growth and monetization goals, transforming the user experience and the company's financial model.

💻 Technical & Operational Impact

  • High Scalability: The Express.js backend, deployed via AWS Elastic Beanstalk, successfully scaled to handle thousands of simultaneous event registrations without performance degradation or service outages.
  • Data Integrity: The PostgreSQL data layer maintained high integrity and fast query times, essential for instantly verifying certification requirements for 70,000+ users.
  • Feature Velocity: The project demonstrated the ability to rapidly deploy complex, high-impact features (payments, events, certifications) on an established platform, ensuring continuous business growth.

The development of the Live Certification module was the single most successful growth driver during this period, significantly increasing the platform's perceived value and converting free users into paying subscribers.
