About
Kurawal
Kurawal — business systems, Odoo ERP, HRIS, and digital transformation, from requirement to production.
Founder
Rain Marpaung · IT Solutions Architect · Full Stack Engineer
I help companies turn business processes into reliable digital systems — ERP workflows, HRIS, internal tools, and integrations — from requirement to production.
With 10+ years of experience across software development, infrastructure, and ERP implementation, I work as both a technical builder and a business solution partner. I combine hands-on development with a practical understanding of operations, approvals, reporting, and production deployment.
I help companies turn manual and fragmented business processes into reliable digital systems — including HRIS, ERP workflows, internal tools, and system integrations.
From requirement gathering and solution design to development, deployment, and user training, I deliver end-to-end business applications that are ready for real operations.
How I work
- Business process understanding before coding
- End-to-end solution delivery
- AI-assisted development for faster execution
- Production-ready deployment and support
