For about 7 years I worked in my first company as a hardware engineer andRF pcb designer. The work consisted in the creation of military devices forRF frequency 1-3 GHz using EMC in programs PCAD,Altium Designer. Theproduction included a full cycle with subsequent testing of finishedproducts in the field.+5 years of professional experience in the IT Technology: IoT,LoRa,wireless,Bluethooth,Wi-Fi (full-lifecycle product development);Rich expertise in development schematic diagramm and multilayers PCB board up to 10 layers, with microcontrollers,microprocessors based on High-Speed interfaces (SPI,I2C,USB,ETHERNET,SATA,HDMI,DDR3,LVDS...)• 7+ years experience in PCB design.•Working with geometry (DXF)• Development of multi-layer printed circuit boards of high complexity (HDI, BGA, MicroVIA, Blind VIA, Controlled impedance board.)Up to 20layers• Familiar with the technique of high-speed signal routing (High speed designer), differential pairs, length control, length matching, no stub routing, etc (PCI, PCI-express, Ethernet, 10G Ethernet, SATA, SAS, IDE, USB3.0 , DDR, DDR2,DDR3, DDR4, Power hight current devices up to100Amps• Experience with EMI and Crosstalk design and practices.• Experience with High Speed design practices.• Understanding of fabrication methods, film processing, board manufacturing and production techniques - including paste/reflow, wave solder, robotic assembly, SMD placement.• Involved in the creation and maintenance of component libraries.(3D models included)• Layer structure preparation (Stack-UP), parameters calculation to meet the impedance of conductors (Single,Differential impedance)• Flexible and flexiblerigid PCBs• Antenna and RF design, according torequred impedance with coplanar ground. Draw schematic in Altiumdesigner and Orcad. Total work experience-20years.Also worked with:Altium designer and Cadence Allegro-use it on my current job for create schematic diagram,PCB design and 3D modelsThe production of the whole needed package of documents for pcb manufacturing (Gerber files, pick&place files, stuckup, mechanical drawing,bill of materials,3D models)Also I have an experience of communication with Chinese manufacturers, finding the solution for best price/quality pcb production

Listed skills include Altium Designer, Cadence Allegro, Pcb Design, Orcad, and 25 others.
