Financial Accounting Assistant – SaaS Web Application

This project focused on improving the performance, scalability, and maintainability of an existing Ruby on Rails application while delivering a robust admin experience and production-ready infrastructure.

The platform includes a dynamic Admin Dashboard, secure file handling, advanced search, analytics tracking, and multi-currency support. Emphasis was placed on clean architecture, automation, and performance optimization to ensure long-term scalability and smooth operations.

The existing system faced performance bottlenecks, limited admin visibility, and growing maintenance complexity. Key challenges included:

Slow and tightly coupled Rails models

Manual admin workflows and limited reporting

Unoptimized file uploads and background processing

Lack of automated deployment and monitoring

Scaling issues with international users and multi-currency handling

The goal was to modernize the backend while ensuring stability and production reliability.

Refactored and optimized Rails models for performance and maintainability

Designed and implemented a dynamic Admin Dashboard using Administrate

Built secure, scalable AWS S3 file uploads with background processing via Sidekiq

Developed responsive UI components using HTML, JavaScript, and AJAX

Designed RESTful APIs for frontend and third-party integrations

Implemented analytics, testing, and automation for production readiness
