Dheeraj Shakya

I’m a Senior FPGA Engineer with experience in embedded systems, digital design, and signal processing. Currently at Varuni Systems, I work on building and deploying FPGA-based communication systems, including real-time data transmission using OFDM and QPSK.

My background spans FPGA development, RF communication, and embedded software, with hands-on expertise in tools like Xilinx Vivado, GNU Radio, Verilog, and MATLAB. I’ve contributed to high-impact projects such as GPON solutions at Tejas Networks and automation frameworks that significantly improved testing efficiency.

I’m passionate about solving complex hardware-software integration challenges and building efficient, real-world communication systems.
