Challenge
A legacy reporting application used by thousands of users lacked critical functionalities — advanced filtering, scheduling, emailing, logging — and delivered a poor user experience.
The system needed a complete modernization: migration from an outdated stack to Vue 3 and Node.js, performance optimization for high-volume report generation, and high-availability architecture to serve a large distributed user base.
Approach
We conducted a detailed architecture design with emphasis on security, performance, scalability, and operational efficiency.
The core application was rebuilt using Vue 3 and Express.js with a modern component architecture. We implemented comprehensive reporting features: advanced filtering and sorting across all columns, multi-format export (PDF, CSV, Excel), email distribution, one-time and recurring scheduling, and centralized logging. The application was containerized with Docker and deployed on Kubernetes with auto-scaling for high availability. We built secure APIs and implemented a lock mechanism for concurrent report generation.
Outcome
Delivered a modern, high-performance reporting platform that replaced the legacy system with zero data loss.
Users gained self-service capabilities for filtering, scheduling, and exporting reports. The containerized architecture on Kubernetes ensures high availability and auto-scaling during peak report generation periods.
