Connecteed represents a complete solution for companies that need to manage their digital presence on multiple platforms. The project required a complex migration of the software from its legacy environment to a modern, containerized architecture with integrated permissions and backup system. My intervention involved a complete code refactoring due to accumulated technical debt, transforming an unstable platform into a robust and scalable digital ecosystem.

Project Overview

The main challenge was twofold: modernize the technical infrastructure while keeping the service active for hundreds of business clients, and resolve accumulated technical debt that impacted performance and reliability. The project required not only advanced technical skills, but also a deep understanding of the SaaS business model and operational continuity needs.

Critical Migration and Refactoring

The migration required careful planning across multiple phases due to the critical nature of the legacy system:

Infrastructure modernization: Complete system architecture redesign to resolve critical storage limitations Platform evolution: Migration towards modern containerized architecture with separated frontend and backend

The system presented a critical storage problem with exponential data accumulation: files were being stored multiple times without proper cleanup mechanisms, causing severe resource consumption issues.

I implemented comprehensive solutions:

• Modern container orchestration for improved scalability
• Granular permission management system with integrated backup
• Automated cleanup mechanisms with intelligent lifecycle management
• Zero-downtime deployment pipelines for continuous service availability

This transformation reduced storage usage by 90% and eliminated consistency issues across environments.

Legacy Issues Resolution

The legacy system presented numerous critical issues accumulated over time:

• Resource management: Inefficient file handling causing exponential storage growth
• Memory management issues causing periodic system instabilities
• Failed data synchronizations due to processing limitations on large datasets
• Database inconsistencies affecting data integrity
• Performance degradation on complex operations

I implemented systematic solutions:

• Intelligent cleanup system with automated lifecycle management
• Complete code refactoring with modern optimization practices
• Strategic caching implementation to reduce database load
• Asynchronous processing architecture for heavy operations
• Robust retry mechanisms for failed synchronizations

Architecture and Results

The platform utilizes a modern separated frontend/backend architecture designed for scalability and maintainability. The frontend provides an intuitive user interface with advanced data visualization capabilities, while the backend handles complex business logic and data processing.

Key architectural decisions:

• Containerized microservices architecture for improved scalability
• High-availability database setup with replication
• Advanced caching strategies for optimal performance
• Intelligent storage management with automated cleanup
• Comprehensive monitoring and logging systems

Implementation outcomes:

The modernization project delivered significant improvements:

• 60% reduction in system response times
• 95% increase in service uptime and reliability
• 10x increase in data processing capacity
• Automatic scaling capabilities based on demand
• Streamlined deployment processes with zero downtime

This transformation established Connecteed as a robust, enterprise-grade platform capable of supporting hundreds of business clients with mission-critical operations.
