I run an established online business on a custom-built PHP site and need a reliable developer to step in whenever hiccups occur. Most of the code is clean and documented, but it still requires periodic attention—bug fixes, minor feature tweaks, security and version updates, plus the occasional performance optimization. There is no rigid schedule: I’ll reach out whenever an obstacle appears or a new improvement is planned, and I expect quick turnaround and clear communication at those moments. You should already be comfortable working with existing codebases, troubleshooting under pressure, and deploying fixes without disrupting live traffic. When you bid, please focus on your relevant PHP maintenance experience rather than sending generic portfolios or lengthy proposals; concrete examples of similar sites you’ve kept running smoothly will help me understand whether we’re a fit. If you value long-term collaboration and can be available on an as-needed basis, I’d love to hear how you’ve handled comparable responsibilities in the past.
