I will build custom CRM erp and business software
Sinan Kinik
About this gig
Need a CRM, ERP, admin dashboard, or custom business application built around your workflow?
I develop custom business software from scratch, not just templates or pre-built CRM configurations.
I can build solutions for:
- Leads, customers, deals, and sales pipelines
- Inventory, orders, suppliers, and purchasing
- Employee and HR workflows
- Admin dashboards and reporting
- Custom business processes and automations
- API and AI integrations
Your application can include a secure database, authentication, role-based access, responsive UI, REST APIs, and production-ready deployment.
I have 10+ years of FullStack development experience, and my portfolio includes working CRM, ERP, HR, and AI-powered business software. Live demos of selected projects are available, so you can explore real working applications before starting your project.
The Basic package is designed for one focused CRM or business module. Larger systems can be built through Standard, Premium, or a custom offer.
Every business workflow is different. For larger or custom requirements, please message me before ordering so we can define the right scope.
