About Bay Area Coffee Service

Why we built Bay Area Coffee Service.

A family-owned shop with real factory training and a phone that gets answered when your machine goes down. Built for cafes and kitchens that need a clear diagnosis and a straight repair plan, not a sales pitch.

The owner

Andrew Kuznetsov, owner.

Bay Area Coffee Service is run by Andrew Kuznetsov, who grew up in an engineering family in Ukraine and came to the United States as a refugee in 2019. He rebuilt his career from scratch in the San Francisco Bay Area in technical field service and founded the company in 2021.

Andrew has always preferred the wrench to the sales pitch. An espresso machine is a pressure vessel with a boiler, pumps, valves, and a control board, and he reads it like one. Engineering instinct first, parts catalog second, no guesswork in the middle. Every call in the early years built into a service playbook we still run today.

We operate out of San Ramon, hold an A+ rating with the Better Business Bureau, and carry California state contractor and EPA refrigerant credentials in good standing. Andrew is a Franke certified service technician, trained on the A-Line and McDonald’s in-house technician programs in 2026. We service La Marzocco, Nuova Simonelli, Astoria, and the rest, and pull genuine Astoria, CMA, and Wega parts through the RCW distributor.

Andrew is lead tech on most calls. When we send a second tech, it is one he trained personally on this playbook. No call center, no subcontractors. If you book Bay Area Coffee Service, that is who walks in.

Zlata Velikaia, co-owner of ADRIUM Service Solutions and Bay Area Coffee Service

Zlata Velikaia, co-owner.

This is a family company: Andrew and his wife Zlata own it 50/50. Andrew runs the tools. Zlata runs the business.

Scheduling, invoicing, the books, licensing and insurance paperwork, vendor accounts — that side of the company is hers. When your confirmation lands on time and the invoice matches the quote, that's Zlata's desk at work. Every job crosses it twice: once when it's booked, once when it's closed.

It's also the plain answer to why the company is listed as a woman-owned business: half of it is owned by a woman, and the business side of it is run by one.
