“They made a big impact on our team, especially on product pages and checkout, always pushing for thoughtful, user-centric improvements. Our discussions on identifying opportunities and framing them with Product Managers were my favourite, both insightful and strategic. They’re proactive, always bringing valuable feedback in critiques, and aren’t afraid to challenge the status quo to create better experiences. Their ability to balance business needs with user needs makes them a strong asset to any team!”**
