Website & Web Server Troubleshooting
Something is broken, but you cannot figure out why? I can help. I troubleshoot website and server problems from the application layer down to the infrastructure—whether you are dealing with a blank white screen, broken connections, 400/500/502/503 errors, server timeouts, PHP or database failures, crashed services, memory problems, slow requests, or unexpected configuration issues. I trace the underlying cause and fix the problem properly, rather than masking the symptoms.
No Fix, No Charge Guarantee
If I cannot successfully resolve the errors or bugs on your website or server, you won't pay a dime.
Fair & Transparent Pricing
We will discuss the price upfront only after I determine the error and the estimated time needed to fix it.
Expert Diagnostics & Server Repairs
When your website goes down or features break, every minute costs you credibility and revenue. Whether you are dealing with an elusive 502 Bad Gateway, database connection failures, sudden CPU spikes, or application-level bugs, I perform deep troubleshooting to isolate the root cause.
I don't just apply temporary band-aids. I analyze server logs, audit your application code, and deploy permanent fixes to ensure stable, resilient operations.

Upwork Review
Troubleshoot Redirected Domains
"Mir is one of the best service providers I have had the good fortune of encountering, on Upwork or anywhere else for that matter. He helped me promptly and graciously at a very difficult moment after my directory had been hacked into and my main domains were all being redirected. I was amazed at how quickly he was able to understand how this had happened and correct the issue. Mir subsequently assisted me with a number of other, related, items, in equally expert fashion. He was consistently prompt, efficient and patient/gracious (given my ignorance about so many aspects of the situation). His English is superb and he also impressed me as a very kind and caring person, as well as highly intelligent. In short, I could not recommend him highly enough."
