During my internship at TechnoHana Training and Consulting, I was responsible for designing, developing, and deploying a robust notification system integrated into the CRM module that significantly improved the communication workflow for end-users and business stakeholders.

Project Overview

The notification system was designed to deliver real-time, multi-channel notifications via email, SMS, and in-app alerts. The goal was to provide timely, prioritized messages that respected user preferences and ensured high availability and reliability across various business scenarios.

Key Responsibilities

• Frontend Development:

  • Developed highly responsive and accessible user interfaces using React.js.
  • Created customizable notification preference panels allowing users to select channels, set priority levels, and configure quiet hours.
  • Implemented real-time UI updates to reflect incoming notifications and status changes using React state management and Firebase real-time capabilities.

• Backend Development:

  • Architected scalable backend services with Node.js, focusing on modular and maintainable code to support notification processing workflows.
  • Designed RESTful APIs for communication between frontend clients and backend services.
  • Integrated MongoDB for flexible and efficient storage of notification data, user settings, and delivery logs.

• Priority Queue & Scheduling:

  • Designed and implemented a priority queue system to manage notification dispatch order based on urgency and user preferences.
  • Utilized cron jobs to schedule batch notifications, retries for failed deliveries, and timed notifications, ensuring robust and timely message delivery.

• Real-time Data & Security:

  • Leveraged Firebase to implement real-time push notifications, enabling instantaneous updates for users without polling overhead.
  • Applied best security practices to prevent unauthorized access and data leaks, adhering to company policies .

• System Integration & Collaboration:

  • Integrated the notification system with the existing CRM platform, ensuring seamless data flow and consistency.
  • Collaborated closely with cross-functional teams .

Impact and Learning

• Successfully launched a feature-rich notification system that improved user engagement and operational efficiency by ensuring critical messages reached the right audience at the right time.
• Gained hands-on experience in managing asynchronous workflows, real-time data streaming, and distributed system challenges.
• Deepened knowledge of full-stack web development tools and frameworks, including React.js, Node.js, MongoDB, Firebase, and cron scheduling.
• Developed a strong understanding of prioritization algorithms and how technical decisions impact business outcomes and user satisfaction.
• Improved collaboration and communication skills by working in a professional Agile environment and receiving feedback from senior developers and stakeholders.

This internship was instrumental in accelerating my growth as a full-stack developer and provided practical insights into building scalable, secure, and user-centered enterprise applications.
