IndonesiaWhat I'm looking for
I’m a highly experienced Architect and construction professional with 20+ years managing residential, commercial, and hospitality projects. I lead site operations with strong project coordination, architectural design/technical review, and construction supervision to keep work aligned with design intent.
Most recently, I’m managing the construction of villas, pools, and facilities as a Senior Site Manager, overseeing workforce and site operations while handling material procurement and logistics. Previously, I reviewed and approved shop drawings, coordinated contractors/subcontractors, issued RFIs and site instructions, and led townhouse, hotel, and apartment projects—backed by detail-oriented quality control and effective team leadership.
