About

Engineering with business context.

Hi, I'm Haris Lukman Hakim.

I am an IT professional focused on system analysis, full stack development, and system integration. I design and deliver end-to-end web and enterprise solutions, from requirement analysis and architecture design to implementation, deployment, and operational handover.

Over 8+ years, I've developed scalable platforms across ERP, Medical CheckUp App, HRIS, payroll, medical, insurance, and logistics domains using PHP, C#, Python, and Node.js with Laravel, .NET MVC, Next.js, and Odoo.

I also specialize in integration-heavy solutions including SAP data synchronization, OPC/SCADA connectivity, AWS-based secure file systems, and WhatsApp automation. My approach is practical, maintainable, and aligned with measurable business outcomes.
