My production web application needs a quick but thorough round of bug fixing and performance tuning. I am seeing issues on both the frontend and the backend, so I need someone who can dive into each layer without disrupting the current architecture. Current pain points • Slow page load times that appear to stem from heavy assets and sluggish database queries • Occasional UI glitches in the layout that throw off the design, plus responsiveness problems on tablets and some mobile devices Your mission Track down and resolve the offending code, tighten up any slow queries or inefficient API interactions, and make sure the interface looks and behaves correctly across modern browsers and major devices. Deliverables 1. Clean, well-commented fixes for the identified frontend and backend bugs 2. Measurable improvement in load speed and database response time (before-and-after metrics) 3. Polished layout with fully responsive behavior 4. A concise report summarizing the changes, tests performed, and recommended next steps I’d like to wrap this up within the next day or two. When you reply, please include a brief note on similar projects you have handled, the tools or approaches you used (e.g., Chrome DevTools, Lighthouse, SQL profiling, caching strategies), and any quick observations you have based on the description above. Clear, timely communication is essential—let’s get this app running smoothly again.
