I will diagnose and fix one clearly reproducible frontend issue on an existing website or web app. Included: • Reproduce the issue and identify the likely cause • Fix one scoped HTML/CSS/JavaScript/React issue • Verify desktop, tablet, and mobile behavior where relevant • Run available build, lint, and tests • Provide a concise handoff with files changed, test results, and remaining risks Good fits include mobile overflow, a broken responsive layout, a visual regression, a simple interaction bug, a broken link or path, or a small accessibility or performance defect. Before starting, please share the URL or repository, reproduction steps, expected result, and current framework or hosting. Redesigns, backend migrations, and multiple unrelated bugs are quoted separately.
