I’m an Embedded Systems Developer with over 13 years of hands-on experience designing reliable, efficient, and production-ready firmware for microcontroller-based products. From writing modular, event-driven C++ code on Arduino and STM32, to building complete low-power systems with sensors, motors, data logging, and communication protocols — I bring deep expertise in embedded development that bridges hardware and software. I have expertise in designing electronic products and thus successfully developed automation solutions for solar plants, PLCs, data loggers, SMPS, VFDs, and much more. My Expertise ✅ Firmware Development – Industry-leading high-quality, optimized, and fail-safe firmware for microcontrollers and embedded systems ✅ PCB Design – Eagle, KiCad ✅ Microcontrollers & Embedded Systems – AVR, Arduino, STM32, ARM, ESP32, NRF ✅ FPGA - worked with Artix 7, Lattice LCMXO2 , Spartan. (HDL coding, mainly verilog and vhdl) ✅ IoT & Connectivity – ESP8266, ESP32, LoRa, Zigbee, Wi-Fi, RF Wireless ✅ Industrial Automation – Designed PLCs, Data Loggers, SMPS, VFDs, Predictive Maintenance System ✅ Communication Protocols – MODBUS RTU, CAN Bus, TCP/IP, UDP ✅ Software Development – GUI development using VB.NET in Visual Studio for device communication I take pride in my highly optimized firmware development process, which ensures precision, reliability, and long-term stability for mission-critical applications.
