About

Senior Field Service Engineer at Prima Power. I handle the full cycle of putting high-tech CNC sheet metal machinery into operation: installation → commissioning → acceptance testing → training the customer's staff at every level, from operators to engineers, in Russian and English.

Currently a Resident Engineer in Saudi Arabia: commissioning a fleet of Prima Power machines and automated lines, introducing preventive maintenance standards, training and certifying technical staff. I take on non-standard problems.

Projects

P-01

Resident Engineer — Saudi Arabia

Riyadh, Saudi Arabia. A comprehensive project: commissioning the Night Train Genius automated production line and a fleet of modern servo-electric machines.
The full sheet metal processing cycle has been successfully launched. The first Shear Genius + LD/STS cutting cell is fully installed, tested and handed over to production (the customer already manufactures on their own).
For bending operations, a fleet of high-precision eP-series servo-electric press brakes was commissioned in standalone mode.
