My production site already works as intended, yet the backend is lagging behind our growth curve. I need a specialist to dig into the current code-base and infrastructure, identify the bottlenecks, and implement the fixes that will noticeably boost speed, tighten database efficiency, and prepare the application to scale without hiccups. Key areas that must be addressed • Speed improvement – faster page and API responses under real-world load • Database optimization – leaner queries, smarter indexing, and healthier connections • Scalability – code, cache, and server tuning that lets us add traffic or new features without rewriting later I will provide full access to the repo, staging environment, and performance logs so you can benchmark before and after. When you reply, include a brief note on similar backend tuning projects you have completed; links or metrics that show the results will help me understand your approach and fit. Deliverables are simple: a commit or pull request containing the changes, a changelog of what was adjusted, and a short report summarizing observed performance gains.
