I can't say enough great things about Matt. He absolutely saved me this week…read more My Lenovo laptop completely failed to boot after a graphics driver cleanup utility corrupted the Windows boot configuration and recovery environment. The system was stuck in a recovery loop, BitLocker was triggered, and Windows wouldn't load or even reliably enter repair mode. Multiple shops I called said it would take several days just to diagnose the issue. Matt turned it around in essentially one day. He was able to manually access the system, unlock BitLocker, repair the corrupted boot configuration, rebuild the necessary Windows files, and get the machine fully operational again -- without wiping my data. That was critical, as I had local files that weren't backed up to the cloud. Beyond the technical expertise, what impressed me most was: * Clear communication * Fast turnaround * Extremely reasonable pricing * No upselling, no unnecessary "reinstall everything" approach He diagnosed the real issue quickly and fixed it correctly the first time. If you're an independent contractor who depends on your machine daily, or you run a small to mid-sized business and need reliable, competent IT support, Matt is exactly who you want on your side. Look no further. Highly, highly recommend.

He is a very knowledgeable, personable, fairly priced and I would highly recommend him to anyone having any type of computer issues.
