Individually those requests are all reasonable; in aggregate they contribute to increased load times and a worse experience for users. Performance here is a question of composition: what queries each page needs before it can render, what queries can add to that set, and how those boundaries hold as the product grows. You'll define those boundaries and make the calls they depend on.</p> <p>This role is frontend-led but architecture-deep and organizationally wide. You'll spend time shaping other teams' designs and building consensus across boundaries, and you'll own execution of your own plans when that's what it takes to land them.</p>
