About

Electronics Engineer with 8+ years of experience working across defence electronics, RF systems, FPGA-based digital design, and embedded platforms, contributing to mission-critical airborne and aerospace systems. My work spans the complete lifecycle from subsystem testing and integration to FPGA/embedded support and system-level validation. I began my career at Astra Microwave Products Limited, where I worked on RF and microwave subsystems for defence applications, gaining strong hands-on experience in RF testing, S-parameter measurements, performance characterization, and environmental stress screening. This role built a solid foundation in real-world RF system behavior and reliability requirements. At Bharat Electronics Limited (BEL), I contributed to Electronic Support Measures (ESM) systems deployed on Indian Navy airborne platforms, working closely with cross-functional teams on RF subsystem testing, FPGA and embedded system integration, system commissioning, calibration, and qualification testing. I supported FPGA receiver processor logic verification and developed MATLAB-based automation frameworks to streamline RF and system validation workflows. All activities were performed in compliance with MIL-STD and aerospace quality standards. Currently, I am working as a Senior Engineer, focusing on embedded firmware development (STM32, RTOS) and FPGA-centric system design, including RTL development using VHDL/Verilog, hardware bring-up and integration of FPGA logic with RF and embedded subsystems.
