About
Technology should make your life easier, not more stressful. I’m Serge, a local IT professional based right here in Boca Raton. With 25+ years of experience as a software engineer in enterprise environments, I bring deep technical expertise along with practical, hands-on problem solving for home and small-business technology. When you work with me, you get my direct line and a commitment to solving your problem the right way, the first time. If the issue turns out to be simple, I’ll explain it clearly and make sure you only pay for the work that actually needs to be done. I specialize in fast, 24-hour turnaround for home and small-business PC & Mac network and hardware issues. My focus includes hardware repair, system optimization, printer troubleshooting, and advanced home and small-office networking. Whether you need pro-grade Wi-Fi setup, router optimization, or secure VPN configuration, I’ve got you covered - no job is too complex for decades of expertise. I am ready to repair, upgrade, build, or install new hardware to ensure your entire system meets the demands of 2026 and beyond. Note: I do not provide iCloud / Activation Lock bypass services and do not install new in-wall Ethernet cabling.

Sergei was amazing! He came to my home on time, reviewed what the issue was and had it fixed and working immediately. I was able to return to work without delay. I would recommend Sergei to everyone who expects a professional to take care of their computer needs. A very happy client, Melissa
