Hired on Thumbtack
Alex did a great job fixing my home security alarm system. He accommodated my schedule and arrived on time. He was professional, patient, and very knowledgeable about my alarm system and the problem that I was having with it. He pre-ordered & purchased the battery ahead of time that I needed. Then to complete the job, he drove 40 minutes out of his way to purchase a missing part that I had somehow lost. And on top of all that, Alex is a super nice person! I would definitely hire him again!

Alex helped me set up my new work laptop and the office workspace. He configured Google Workspace/Gmail Business, updated the DNS records for the domain, checked email delivery and made sure everything was working correctly.
He also connected the monitors, dock, peripherals and configured the office network. I’m a C++ developer, so I needed a reliable setup for daily work, not just basic installation. He tested everything, fixed a couple of connection issues and explained what was changed.
Everything works well and the setup has been stable. Alex knows both hardware and networking, and was easy to work with. I would use his services again.

Alex has helped us with several projects over the past few months. It started with TV mounting, but over time he also helped with Sonos setup and integration, built-in speakers, security cameras, a smart doorbell, garage door opener installation, Wi-Fi improvements, and a number of other technology projects around the house.
What I liked most was that he didn't just focus on the immediate task. He took the time to understand how everything worked together and helped improve the overall setup. Whenever we ran into an issue, he was able to figure it out and explain the options clearly.
We've hired Alex multiple times and have always been happy with the results. He's reliable, knowledgeable, easy to work with, and takes pride in doing quality work. I would definitely recommend him for smart home, networking, audio/video, TV mounting, and other home technology projects.

Alex is my guy. Since we moved into our house he’s mounted 5 TVs including three 100 inch TVs, set up the whole Wi-Fi system for all 3 floors plus the backyard and pool, handled cable management, hung 30+ pictures and mirrors, and assembled most of the furniture. Everything came out solid and clean. I just text him whenever I need something done. Highly recommend.
