Hire the Best Embedded Applications Freelancers
in India

I am an embedded systems consultant and entrepreneur with 15+ years of experience developing products from concept to production across startups and multinational companies. My expertise spans system architecture, schematic design, PCB layout, embedded firmware, prototype bring-up, testing and product validation. I specialize in transforming product ideas into reliable, manufacturable embedded systems. Rather than simply designing PCBs, I engineer complete products by balancing hardware, firmware, performance, cost, reliability and manufacturability. **Representative projects include:** * Multi-axis robotic assistive devices * Air purification and environmental monitoring systems * IoT-based monitoring and control platforms * Automated hydroponic and smart agriculture systems * Sensor acquisition, motor control and HMI development * Bluetooth and wireless-enabled embedded products I have worked with a wide range of technologies including digital and analog sensors, power electronics, motor drivers, wireless communication, MCU-based systems and embedded user interfaces. This breadth allows me to quickly understand complex requirements and develop practical, scalable solutions. Whether you need a product designed from scratch or improvements to an existing design, I can help with: * System architecture and component selection * Schematic capture and PCB design * Embedded firmware development * Prototype bring-up, debugging and validation * Design for Manufacturability (DFM) and production readiness Alongside embedded product development, I continue to expand my expertise in hardware-software co-design, FPGA SoCs and RISC-V systems, enabling me to tackle increasingly complex embedded applications.

I'm a hardware and embedded systems engineer with 8+ years of experience in PCB design, embedded firmware, and scientific instrumentation, currently working on geomagnetic sensing and space-mission hardware. My work spans schematic design and multilayer PCB layout, embedded firmware development (ESP32, Raspberry Pi Pico/RP2040, FPGA-based systems), and full assembly-integration-and-testing (AIT) of flight hardware for sounding rocket and balloon payloads. Core skills: PCB design and high-speed layout (Altium Designer, Easyeda, Auto desk Eagle) Embedded firmware: ESP32, RP2040/Pico, PIO-based real-time capture, ISR-driven timing control, UART/I²C/SPI peripheral integration FPGA design: for precision timing and measurement systems Sensor and instrumentation systems: precision frequency/timing measurement, sub-nT magnetic field sensing, data acquisition and logging (SD/SD_MMC) Flight hardware AIT: Field deployment and testing at high-altitude observatory sites, sounding rocket payload integration M.Tech in VLSI Systems (NIT Trichy), prior teaching experience, peer-reviewed publications in instrumentation I take projects from architecture through schematic, layout, DRC/ERC, prototype bring-up, and field debugging, not just isolated design tasks. I provide clear documentation, realistic timelines, and direct communication throughout.
