Shadab R.

Need hardware that actually works in the field? I design PCBs and write embedded firmware for ESP32, STM32, Arduino and Raspberry. From schematic to production-ready prototype. Having 25+ years of hands-on experience. Clean layouts, stable firmware, and real-world tested results." I’ve worked extensively with microcontrollers, processors SOCs and development boards. My work includes 𝗲𝗺𝗯𝗲𝗱𝗱𝗲𝗱 𝗰𝗼𝗻𝘁𝗿𝗼𝗹𝗹𝗲𝗿𝘀, 𝗜𝗼𝗧 𝘀𝘆𝘀𝘁𝗲𝗺𝘀, 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 𝗰𝗶𝗿𝗰𝘂𝗶𝘁𝘀, and wireless communication setups such as 𝗪𝗶-𝗙𝗶, 𝗕𝗟𝗘, 𝗟𝗼𝗥𝗮, and 𝗚𝗦𝗠. 𝗜 𝗰𝗮𝗻 𝗵𝗲𝗹𝗽 𝘆𝗼𝘂 𝘄𝗶𝘁𝗵: • PCB design (KiCad, EasyEDA, Altium) • Firmware development in C/C++ • ESP32/STM32 projects • Sensor automation & motor/servo control • MQTT/Firebase IoT dashboards • Long-range wireless communication • Converting ideas into working prototypes My approach is 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗮𝗹 𝗮𝗻𝗱 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲-𝗱𝗿𝗶𝘃𝗲𝗻. I focus on clean 𝗰𝗶𝗿𝗰𝘂𝗶𝘁 𝗱𝗲𝘀𝗶𝗴𝗻, 𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲𝗱 𝗳𝗶𝗿𝗺𝘄𝗮𝗿𝗲, and proper debugging to ensure 𝗹𝗼𝗻𝗴-𝘁𝗲𝗿𝗺 𝘀𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆. If you need a senior engineer who understands electronics from the 𝗳𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻 𝗹𝗲𝘃𝗲𝗹 and can deliver a 𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲, 𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻 then i am your guy.
