I am looking for someone who: Has strong experience with CodeIgniter (legacy projects), MySQL/MariaDB performance, and PHP-FPM/Apache. Can: Read existing code and logs, Identify all internal HTTP self-calls, Optimize the critical queries and DB indexes, Tame high-frequency polling endpoints like /noticnt, Remove bad patterns like global SQL mode changing from PHP. Works carefully in production: No wild experiments directly on live without backups. Explain what changes you plan to make. Provide before/after timings (e.g., curl TTFB, reduced queries). If you’re interested, please: Mention similar performance optimization work you’ve done on CodeIgniter or similar LAMP stacks. Propose a rough action plan: Step 1: audit & confirm, Step 2: fix internal curl + /noticnt polling, Step 3: refactor heavy queries/indexes, etc. I already have: Access to server logs and code, Clear pointers to problematic functions and routes (as listed above). I need someone who can own the clean-up, make the application efficient, and stop the pattern where the site is fast after restart but then becomes slow again over time.
