I can take a focused audit to remove the transactional stalls that appear under peak load and stabilise the backend.
One important nuance to watch is long-running transactions causing row locks and high contention when indexes are missing.
Could you attach a recent slow-query log or a short profiling snapshot so I can identify the worst offenders and reply with concrete next steps?

Hello! I have over 9 years of commercial PHP development experience, having worked with practically every possible tech stack. I have deep, hands-on expertise in e-commerce architecture, optimizing heavy MySQL databases (including profiling and cleaning up multi-gigabyte tables), and fine-tuning Redis caching. I would be glad to help you conduct the audit, resolve performance bottlenecks, and refactor the legacy code within your specified milestones. Ready to discuss the details!
