Hunel
HR Tech Transformation
Modernized legacy HR systems with intelligent automation and modern architecture.
The Challenge
Hunel had a legacy HR management system that was struggling to keep up with modern workforce demands. The system was built on outdated technology, making it difficult to add new features, and the user experience was causing adoption problems. They needed a modernization that could happen without disrupting their existing customer base.
The challenge was compounded by complex integrations with payroll systems, time tracking tools, and compliance requirements across different jurisdictions.
The Approach
Applied the Strangler Pattern to gradually migrate from legacy to modern architecture
Built new features in a modern stack while maintaining backward compatibility
Redesigned the user experience with a focus on daily HR workflows
Implemented intelligent automation for repetitive HR tasks
Created a unified API layer to simplify third-party integrations
The Stack
Frontend

The Outcomes
Key Insight
" The hardest part of legacy modernization isn't writing new code — it's understanding why the old code exists. We found multiple "bugs" that were actually features customers depended on. Taking time to document existing behavior before changing anything saved us from breaking critical workflows that weren't in any specification. "
