About

Field Service Engineer at Siemens Energy with 10+ years of hands‑on field experience across international industrial and power projects. I operate where engineering meets real‑world execution: installation, coordination, site supervision and safe handover of critical equipment—always with a strict focus on reliability, safety and uncompromising quality. In my current role I support multiple photovoltaic power plant and substation sites in Bulgaria and Romania, delivering successful installations of: • Siemens compact switchgear 3AP1 DTC 145 kV • 3AP1 FG 145 kV circuit breakers (including multi‑unit deployments) • Power transformers in configurations 110/20 kV, 110/33 kV, 110/33/6.9 kV, with ratings up to 70/100 MVA and 80/105 MVA On several sites I also take Site Supervision responsibility—planning and sequencing activities, coordinating teams/subcontractors, tracking progress, and ensuring workmanship and documentation meet project standards. Previously, as Electrical Field Supervisor with SGS Industrial Services, I contributed to the 783 MW CCGT Flémalle project in Belgium (Siemens SGT5‑9000HL), supporting cable routes, instrumentation and motor cabling, medium‑voltage cable works, and installation of power/operational panels in PCCs. With Christof Industries I worked on top‑tier grid and industrial modernization projects, including the Amprion Schwanheim 420 kV GIS (SF6) substation for Siemens Energy (6 bays, 8DQ1‑1 with GIB and coupling bay), plus decarbonization and plant upgrades such as the Koehler Paper boiler house renovation (cable route upgrades, instrumentation cabling replacement, MCC panel replacement/upgrade). I also have experience in automation/logistics, including conveyor system installation for the AEON/Ocado project in Tokyo. What you can expect from me on site: disciplined execution, structured problem‑solving and troubleshooting, strong HSE mindset, clear communication with multicultural teams, and consistent delivery under real conditions—because in the energy sector, “almost finished” is not an option.
