Project Overview

Led backend architecture and development for Hoo Talk, a digital consumer intelligence platform designed for startups to analyze, monitor, and act on online conversations. Inspired by Brandwatch, the platform enables businesses to track consumer sentiment, trends, and engagement in real time. I designed the backend architecture and models, built the full payment and subscription system (supporting plans, upgrades, and flexible feature toggles), and developed the dashboard module for analytics and insights. Security was a core priority, ensuring robust endpoint protection and compliance with industry standards. Collaborated with the team to deliver a scalable and flexible system ready for growth.

Key Features

• Flexible Payment System: Designed and implemented a modular subscription engine with payment plans, upgrades, and feature-based billing.
• Analytics Dashboard: Developed a backend-driven dashboard for real-time consumer insights, sentiment analysis, and trend monitoring.
• Scalable Architecture: Created a backend architecture and data models that allow independent feature development and future scalability.
• Secure Authentication & Endpoints: Integrated Keycloak for role-based access control and enforced security best practices across all APIs.
• Business Intelligence: Enabled businesses to analyze online conversations similar to Brandwatch, providing actionable consumer intelligence.

Challenges & Solutions

The biggest challenge was designing a flexible system capable of handling multiple subscription tiers, payment flows, and feature upgrades without creating technical debt. I solved this by developing a modular payment module where each feature could be independently activated or upgraded. Another challenge was securing sensitive endpoints while maintaining scalability, which was addressed through robust authentication, encryption, and API security layers.
