What I'm looking for

I want a role in maritime navigation or shipping/port operations where I can ensure safety and compliance, manage certificates and documents accurately, and support crew recruitment and vessel coordination with strong responsibility and adaptability.

I’m a maritime professional with experience across port operations, crewing, and vessel administration, with a strong emphasis on compliance and maritime safety. In my Harbour Master role, I handled ship certificate issuance, verified certificate requirements, and managed data and document administration to keep operations running smoothly.

Previously, I supported operational vessel needs by checking ship certificate validity, coordinating vessel berthing and unberthing, and helping coordinate vessel entry into Indonesia with the required permits. Earlier, as a Crewing Staff, I verified Certificate of Competency (COC) and Certificate of Proficiency (COP), arranged crew sign on/sign off, and managed recruitment for vessel crew.
