✅ 100% Client Satisfaction ✅ Top Embedded and Firmware developer ✅ Top Hardware designer ✅ Top Software design ✅ Top Mechanical design and industrial design ✅ Top Enclosure design I'm a Certified Multidisciplinary Product Design Engineer with more than 10 years of hands on experience in product design, development and manufacturing support. Using SolidWorks, AutoCAD, and Autodesk Inventor, I help clients turn early ideas, sketches and existing models into practical products that can be prototyped and manufactured. I enjoy solving the details that make a design work in the real world not only making it look good on the screen. That means thinking carefully about how each part fits, how the product will be assembled, where the electronics will sit, and whether the manufacturer can produce it efficiently. Services: 1) Hardware/Electronics design (Power, Analog, Digital/High-speed and RF electronics design) 2) Precertification testing (EMI, ESD, EMC, FCC, CE, UL) 3) Firmware design С/C++ (Bare metal MCU/MPU, FreeRTOS, Zephyr RTOS, Embedded Linux, Wireless protocols, Security, Interfaces, etc) 4) Industrial and Mechanical design (Enclosure design, 3D printing, IP standards, Prepare all for injection molding, etc) 5) UX/UI design (Embedded devices with displays, Mobile and Desktop applications) 6) Software design (Android, IOS, Linux kernel and user space development) 7) Embedded Quality Assurance(QA) and testing 8) Manual verification/testing PCB/FPC, functional and unit testing of the Firmware/Software, stress testing, temperature range testing Service->Hardware design service: - Power electronics design: (PFC, Solar charging controller, chargers, high voltage control, Motor controllers DC/AC/BLDC ) - Analog electronics design: High-accuracy analog measurements, Noise filtration, Digital to analog conversion, Amplifying signal - Digital and high-speed electronics design: - Memories DDRx/LPDDRx, SDRAM, Camera and display interfaces (MIPI-DSI, MIPI-CSI, DisplayPort, etc), Data communication interfaces (QSpi, SPI, UART, I2C, FMC, I2S, USB 2/3.x, etc), ( - RF Designs: ( 50-60 GHz (Radars), 1-6 GHz (UWB, Wifi, BLE, ZigBee, GPS, NB-IoT, LTE-M/LTE, Z-Wave, etc), 13,6 MHz, 128 kHz (NFC, RFID, etc), 433 MHz (Custom protocols) Service -> Industrial and Mechanical Design Industrial concept design : I develop several suitable design ideas based on the product's size, purpose, industry, appearance and user experience. Mechanical CAD design : I create accurate 3D parts and assemblies with practical dimensions, tolerances, materials, fasteners and manufacturing details. PCB integrated enclosure design : I design the enclosure around the actual PCB, battery, buttons, display, antennas, connectors, sensors and wiring rather than treating the electronics as an afterthought. Design review and problem solving : I look for interference, weak features, poor alignment, difficult assembly, leakage risks, heat buildup, and other issues that may cause trouble during prototyping or production. Technical drawings : I prepare clear manufacturing and assembly drawings, exploded views, BOMs, and properly organized STEP, STL, DWG, DXF and PDF files. Thermal calculation and simulation : I evaluate heat sources, airflow, enclosure temperature and cooling options to help protect the electronics and maintain reliable operation. 3D printing and verification : I prepare print ready models and use prototypes to check fit, PCB placement, button movement, fastening, accessibility and complete assembly. Injection-molding preparation : I refine wall thicknesses, ribs, bosses, draft angles, fillets, parting considerations and other details needed for practical mold production. Cost and manufacturing optimization : I look for sensible ways to simplify parts, reduce material use, shorten assembly and control production costs without weakening the design. Service -> Project Support I organize the work into clear stages so you always know what is being developed and what will be delivered. I communicate directly and honestly, especially when I see a technical risk or a simpler way to solve a problem. I work comfortably with clients, electronics engineers, manufacturers and prototype shops to keep everyone aligned. I remain involved through reviews and revisions so the final files reflect both the design intent and the realities of manufacturing.
