Overview
GC Europe is an enterprise operations and workflow management platform built for European clients. The system handles complex business processes across multiple departments, automating workflows that previously required manual coordination.
The platform integrates with existing enterprise tools while providing a unified interface for operations management, task tracking, and cross-team collaboration.
My Role
As lead software engineer and systems integrator, I owned the technical implementation:
- Systems Integration — Connected platform with existing enterprise software
- Full-Stack Development — Built both the Node.js backend and React frontend
- Workflow Engine — Designed and implemented the automated workflow system
- API Development — Created REST APIs for internal and external integrations
- Performance Optimization — Ensured system handles enterprise-scale loads
Architecture
Enterprise architecture designed for reliability and integration:
Backend
Node.js with Express. Service-oriented architecture for independent scaling. PostgreSQL for relational data with strong ACID compliance.
Workflow Engine
State machine-based workflow execution. Queue-based task processing for reliability. Retry logic and dead-letter handling for failed operations.
Integration Layer
Adapter pattern for connecting external systems. Webhook support for real-time updates. Rate limiting and circuit breakers for resilience.
Frontend
React with TypeScript. Role-based UI rendering. Real-time updates via WebSocket. Internationalization for European markets.
Hard Problems
1. Legacy System Integration
European enterprises run on decades-old systems. Built adapters for SOAP APIs, fixed-width file formats, and proprietary protocols.
2. Multi-Language Support
Platform needed to work in 6+ languages with different date/number formats. Implemented robust i18n with locale-aware formatting.
3. Compliance Requirements
GDPR and industry-specific regulations required careful data handling. Built in data retention policies, export tools, and audit capabilities.
4. Workflow Complexity
Business processes had dozens of conditional branches. Created a visual workflow designer that non-technical users could modify.
What I'd Improve Today
- Add low-code workflow builder for business users
- Implement event sourcing for better audit and debugging
- Use GraphQL for more efficient frontend data fetching
- Add AI-powered process mining to identify bottlenecks
- Containerize with Kubernetes for better scaling
- Implement comprehensive observability with distributed tracing
