My core-PHP application has started throwing a mix of runtime errors, warnings, and a few stubborn logic issues inside the backend processes. I will hand over the full source code along with server or local environment access and simply need you to hunt down every culprit, patch it cleanly, and leave the project running exactly as intended—no new features, no visual tweaks, just solid error resolution. Here is what the engagement looks like: • Pinpoint and eliminate all current errors and warnings. • Refactor only what is necessary so the app runs smoothly end-to-end. • Keep me posted on findings; clear communication is key. The budget is a fixed ₹1200 and the turnaround I have in mind is 1–2 days, depending on how deep the issues go. If you are comfortable with focused PHP debugging, have a knack for tracing backend problems quickly, and agree to the fixed rate, let’s get this sorted right away.
