About
I bring a professional, outcome-focused approach to computer and tech help, not guesswork or rushed fixes. I have several years of hands-on experience supporting Mac and Windows users, setting up home offices, troubleshooting networks, and helping people make their technology work reliably and securely.
What sets me apart is scope discipline and clarity. I don’t oversell or complicate problems. I identify the real issue, explain options in plain language, and implement the right solution the first time—whether that’s speeding up a slow computer, stabilizing Wi-Fi, securing accounts, or setting up backups so problems don’t come back.
I operate lean and independently, which means:
• No upsells or unnecessary hardware
• Faster response times
• Lower overhead passed on as fair pricing
• Clean, documented setups you can understand and maintain
My goal is simple: reduce frustration, increase reliability, and leave you with technology that just works.

Sebastian has helped our nonprofit, ChileMass, several times with computer setup, troubleshooting, and printer devices. He is very attentive to detail, works efficiently, and is great at explaining technical issues in a way that is easy to understand.
Whenever we’ve had problems with our computers, he’s been able to diagnose the issue quickly and get everything working again. He’s reliable, patient, and clearly knows his way around technology. I highly recommend him to anyone who needs help with computers or tech support.
