What I'm looking for

I am seeking HR/administration roles that value accuracy, data-driven decision-making and multilingual communication, offering stability, cross-functional collaboration and opportunities to work on AI moderation or back-office analysis.

I am an experienced HR and administrative professional with extensive experience across corporate, construction, maritime and tech environments, delivering precise office management, HR operations and back-office analysis.

I have led recruitment, payroll, policy creation and employee relations, managed invoicing, accounts and reporting, and supported projects with timekeeping, procurement and ERP/CRM tools. I also worked as a moderator and AI trainer, refining datasets, tracking errors and improving model performance.

I bring strong multilingual communication, meticulous data reporting and a pragmatic, problem-solving approach. I seek opportunities to combine HR, administration and analytics to streamline processes and support teams to perform at their best.
