Whether you need help with prototyping, validation, troubleshooting, or building reliable engineering workflows, I can help. - Experience with RF systems, embedded hardware, Python tools, and lab/test automation - Loves to work on long-lasting custom wearable tech! - Support from concept development through integration, validation, and production handoff - Strong communication, documentation, and cross-functional collaboration

# Altium Designer # Work on complex designs with FPGAs (>1000 pins), CPUs, DDR2/3/4, Ethernet Switches. # Most designs have USB, SATA, RGMII, SGMII, 1G/10G Eth, PCIe. # Controlled impedance/length matching, via back-drilling, blind/buried vias, HDI. # Designs range from small (<100 comps) to large systems (multiple PCB >2500 comps each). # Worked on Automotive, Mil-spec, Space, High Power (> 50A, > 500V), Audio, Mixed A/D, & RF. Services provided: # PCB Layout -- High Speed, Mixed A/D, RF, Audio, High Power, Telecom, Test, Mil-spec. # Schematic Capture -- Hierarchical or Flat, BOM selection, Sim/Signal Integrity. # Library Management -- Schematic symbol, PCB footprint, integrated 3D info in footprints. # Electronic Design -- High Speed, A/D, Audio, Mixed. # Electronic Design starting from the ground up to the end.

With more than 15 years of experience developing electronic devices, I have been leading R&D and manufacturing teams using innovative approaches to design, test, assembly and validateinnovative products. I am an experienced electrical engineer with experience developing innovative products integrating technoligies, such as RFIDs, Battery Management Systems, Robots, Drones and IoT devices. I provide my customers with the engineering packages to be transfered to manufacturing. I develop and guarantee my customers the suppy chain for their products. I have a fully equipped laboratory to design, prototype and validate the systems. I have also access to capabilities for microfabrication (cleanroom facility) for the development of sensors and integrated circuits.

• PCB Design (New and Sustaining): Schematic Capture / Layout in Altium Designer • PCB Level Hardware Prototyping, Debug, Assembly • Contract PCB Manufacturer Management • Microcontroller Firmware Development in C (5000 lines of code or less)

I am a senior electronics and embedded systems engineer with 47 years of experience in hardware design, firmware development, PCB layout, debugging, testing, and product development. I help clients turn electronic product ideas, prototypes, and hand-wired circuits into working embedded systems and manufacturable PCB designs. Typical projects I can help with include: * ESP32 and STM32 / STMicroelectronics MCU-based products * Power conversion and low-power battery-powered product design * Custom wireless and RF communications, including LoRa and ESP-NOW peer-to-peer networking * Circuit design and component selection for manufacturing * Schematic entry and multi-layer PCB design. * Ordering fabs and coordinating assembled boards. * C/C++ firmware for sensors, displays, audio, wireless, and control systems * Embedded graphics and touchscreen user interfaces using LVGL * Digital audio filtering, FFT spectrum analysis, and voice activity detection * Cloud API integration for speech-to-text, text-to-speech, and language translation * Embedded bus and peripheral interfaces: I2C, SPI, I2S, UART, RS-485, CAN, and SD/MMC * Prototype debugging and board bring-up * Converting breadboard prototypes into clean PCB designs * Design reviews before manufacturing * Analog and digital circuit troubleshooting * Production-oriented improvements for reliability and manufacturability I have founded and managed engineering companies and consulting firms, led technical teams, and helped bring electronic products from initial concept through prototype, testing, manufacturing, and production. For clients, this means fewer design mistakes, faster debugging, lower development risk, and a clearer path from concept to a working, manufacturable product.
