Hi, I have strong experience in both PHP/CodeIgniter and C# ASP.NET MVC5, and I can successfully migrate your Perfex CRM system with full feature parity, preserving its existing UI while significantly enhancing performance, scalability, and security. A key technical challenge is replicating the dynamic behavior and third-party integrations in a new tech stack—I address this through modular development, unit-tested service layers, and careful mapping of CodeIgniter controllers to MVC5 patterns. I will mirror the UI precisely using Razor views and Bootstrap, while optimizing backend logic with async processing, Entity Framework, and caching strategies. I’ve handled similar CRM migrations, improving response time and adding data encryption, input sanitization, and secure authentication layers. Thanks, Hercules
