    A multi-disciplinary inventor and designer with expertise in quartz crystal and SAW technology, materials science, electronic design, antennas and RF, RFID, embedded firmware and hardware design, and much more. I am a creative and innovative problem solver who is equally comfortable with the big picture or working out the small details in an ongoing project. More recently I have been working with BLDC controllers up to 48V/600W and with charge controller layouts. In December 2021 I retired from IntelliSAW and began only consulting. I am seeking projects between tens of hours and 100 hours or so in scope with availability about 24 hours a week. I have been Florida-based for the past five years, but since July 2021, I am working remote in Belize. This relocation will impact shipping for any hardware support but will not affect my ability to perform design work or design reviews.

    As an engineer that has spent my entire career helping startups, I know what it takes to create an MVP quickly and on a limited budget. Multiple times I have been part of a small team taking a product from concept to production run. Each time the requirements have been different, ranging from consumer IoT devices to industrial robots. A holistic view and clear communication is the key to a successful project. At my last full-time role, I was a product owner and worked in customer success. There I developed a highly customer-focused approach to my work. Combining this with an agile working methodology, I can help ensure you get what you need through quick iterations and constant feedback. This means you always understand how the project is progressing and are able to quickly provide input, so costly changes (time & money) can be avoided. While I have a broad range of skill-sets, my core strengths - built through studying at a world leading university and years in industry - are as follows: * Firmware (C/C++) - this has been a major part of all of my previous full-time roles, including in a robotics company where safety and reliability is mission critical. I have worked with a wide range of MCUs, interfaces, wireless technologies and sensors. * Circuit & PCB design (KiCAD) - my highlight is a small wearable I designed for Felcana and took to production in China. On a board measuring just 12 x 25mm, I squeezed in an MCU, large flash storage, multiple sensors and two wireless front-ends (BLE & LoRa). * Prototyping - whether it's for a trade show, grant application or the first customer, I've been there! The key to my success is having laser focus on the bare minimum required to get the desired outcome. Once you're ready to start working with me, the first step is to schedule a call. During this, we will go over your project to ensure we're both clear on expectations. Then, we will establish how we will communicate going forward and how often. Following this, work will commence with frequent updates & opportunities for feedback. So if you have an embedded project and are looking for a proficient engineer that iterates quickly and keeps you at the centre of attention, message me today.

    1) RF System & mmWave I'm a RF engineer having more than 20+ years experience in the development and production of RF system and Antenna and other electronic device development. I have rich experiences in designing of RF system and programming of several MCUs and high performance FPGAs. I also used to design various wireless circuits such as the antenna, the power divider, the directional coupler and so on using RF simulation program such as CST and ADS. I have plenty of experience designing embedded devices using many types of micro-controller or wireless modules. In this period, I have used various sensors such as cameras and have experience in driving LCD display and LED matrix display devices, and also have experience in controlling motor and design of audio circuits. Some of these devices have the modules of Ethernet, Bluetooth, WiFi, zigbee, LoRA, GSM, NBIOT and so on. I am designing the devices using the Altium Designer, CST Studio, ADS, AutoCAD, Solidworks and so on. 2) Development of firmware For high efficiency and high reliability, I have used to develop my own firmware of the devices which I have designed by myself. I have used several applications such as Quartus (including ModelSIM), Keil IDE, IAR IDE, MPLAB X IDE, Atmel Studio, Arduino and ESP-IDF for the firmware's development. I have a wealth of experience writing an RTOS-based firmware. I also developed many firmware based on various communication protocols such as RS485, CAN, MQTT, TCP / IP and NB-IOT. Of course, many more modern IOT-related firmware using Bluetooth, WiFi, and zigbee have also been developed. 3) Product Sourcing Agent I have been involved in electronic product development for a long time, and I have full experiences of a comprehensive research, development and production from electronic product design to production completion. Of course, for marketed goods, I have also my own methodology to manage whole processes to ensure that our products have the competitiveness in the world market. Actually, I have enough experience in the previous company to produce the access controllers of more than 50,000 per month for more than 7 years.
