Introduction: Choosing the Right Path for Modern App Development

As businesses aim to automate processes, improve customer experiences, and modernize internal operations, the need for custom software has skyrocketed. But the question every business owner and IT leader faces is:

This decision will impact:

  • Development speed

  • Scalability

  • Security

  • Maintenance

  • Integration

  • Long-term ROI
