“Different sectors have different appeals”
“I've always done a lot of international work, particularly on cross-border disputes or global rights clearance projects. Europe and US are the markets that I've worked with most, followed by Asia.
Different sectors have different appeals. The challenging and enjoyable thing about tech is its ever-evolving nature - and having to apply the law creatively, to address new concepts, like AI. With retail, it’s the relatability - everyone understands and is interested when M&S and Aldi fall out over caterpillar cakes! With insurance, it’s the variety of claims that the business model yields, plus being able to assist businesses who wouldn't necessarily be able to instruct us if they weren't insured.
I'm very dedicated and committed to client matters and go above and beyond to provide a tailored service based on individual client needs. I also like to think that I'm responsive, approachable and very easy to work with from a client perspective.”
