My childhood hobby was taking something apart and putting it back together. As I grew older, I became fascinated with electronics and completed BSC on EEE. Over the last 10 years I have developed some consumer and IoT products for RISO, ME-Solshare Ltd, Walton Micro-Tech Corporation, Sinetek Ltd, ERROR Lab and I've acquired some rather unique skills along the way in embedded systems, RF/wireless, and harsh environment systems. In most of my projects I have developed firmware using TTD (Test-driven development), maintained firmware versions properly by git and followed industry best practices. 𝐌𝐲 𝐒𝐤𝐢𝐥𝐥𝐬: • 𝐋𝐚𝐧𝐠𝐮𝐚𝐠𝐞𝐬: C, C++, and Python • 𝐄𝐦𝐛𝐞𝐝𝐝𝐞𝐝 𝐎𝐒: Embedded Linux, Free RTOS, and Amazon free RTOS • 𝐏𝐫𝐨𝐭𝐨𝐜𝐨𝐥𝐬: UART, SPI, I2C, RS485, and WG26 • 𝐖𝐢𝐫𝐞𝐥𝐞𝐬𝐬: WIFI, BLE, GSM, GPRS, IR & RF • 𝐌𝐢𝐜𝐫𝐨𝐜𝐨𝐧𝐭𝐫𝐨𝐥𝐥𝐞𝐫𝐬: STM32, ESP32, Nordic, PIC and AVR • 𝐃𝐞𝐯 𝐁𝐨𝐚𝐫𝐝𝐬: Arduino (Uno, Mini, and Mega), STM37H745, NUCLEO-F070RB, ESP32 Devkit, NRF52840-DONGLE • 𝐆𝐔𝐈 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: TouchGFX • 𝐏𝐂𝐁 𝐃𝐞𝐬𝐢𝐠𝐧𝐢𝐧𝐠: Proteus, Altium • 𝐒𝐢𝐦𝐮𝐥𝐚𝐭𝐢𝐨𝐧: Proteus, Multisim, LTspice • 𝐒𝐜𝐡𝐞𝐦𝐚𝐭𝐢𝐜 𝐃𝐞𝐬𝐢𝐠𝐧: Designed SMPS, Inverter, and some circuits for home automation, IoT energy meter, IoT Attendance Machine and home appliance products. • 𝐂𝐢𝐫𝐜𝐮𝐢𝐭 𝐓𝐞𝐬𝐭𝐢𝐧𝐠: Performed circuit analysis, signal integrity, and reliability testing of different circuits. I have a lab at home with all the necessary hardware/firmware development equipment including oscilloscopes, signal generators, power supplies, power loggers, uA meters, soldering stations, development boards, etc. It's highly likely I have already worked with the technologies you need to make your project successful. Thank you for taking time to consider me for your project.
