What I'm looking for

I seek a role combining e-commerce and operations leadership where I can improve inventory accuracy, optimise fulfilment, and drive marketplace growth in a collaborative, improvement-focused team.

I am an operations and e-commerce specialist with hands-on experience leading store and digital marketplace workflows, inventory control, and financial processes. I specialise in marketplace management across TikTok Shop, eBay and Vinted and building fulfilment and packaging workflows that reduce losses and improve customer satisfaction.

As Acting Assistant Manager at Clarkes of Sussex I manage end-to-end store operations, financial reconciliation, stock control, supplier purchasing and rota planning while maintaining audit compliance and zero discrepancies. I founded an online brand and freelance operations service, growing visibility through SEO, algorithm-driven optimisation and process improvements that increased repeat buyers.

I combine practical retail leadership with data skills—Power BI, Excel Macros, VBA and Access—to improve accuracy and reporting. I deliver measurable results in inventory accuracy, packaging optimisation and operational resilience, and I am proactive, organised and focused on continuous improvement.
