Work Experience Summary:I am a Senior SDE (L6) at Amazon Development Centre India with 12+ years of expertise in embedded firmware development, specializing in IoT, wireless technologies, and storage systems. I hold a B.E. in Electronics and Communication Engineering with CGPA:9.08.Currently, I lead/hands-on firmware development for Amazon Ring products (Doorbells, Cameras, Chime devices) and FireTV BLE Remote Controllers. My work includes unified architecture across multi-platform devices with various SoCs (ESP, MTK, Amazon, RTK, Telink), ownership of memory-constrained MCU projects, and cross-functional collaboration with App, Backend, Connectivity, Multimedia, QA teams and SoC vendors. I won the Amazon DemoCrawl event for developing a fingerprint authentication PoC for FireTV profile switching. Actively leverage AI tools daily for enhanced development efficiency.As Software Engineer at Cisco Systems, I contributed to NCS5500 router platform infrastructure, implementing boot time optimization, interrupt handler enhancements, and an auto-triage framework. I automated comprehensive test suites for Module Port Adapter (MPA), developed the Board Definition File Generation tool with plugin architecture and Python Flask web UI, and filed a patent on \"Network Packet Handling in Transport Domain.\" I achieved top 10 finalist position in a company hackathon.As Staff Firmware Engineer at Western Digital Corporation, I developed firmware for SD/microSD cards across multiple memory technologies (BiCS4/BiCS5/BiCS6), implementing closed block management, block exchange for multi-metaplane support, and dynamic relinking. I led product ownership for Ultra Speed Bump cards and conducted memory architecture analysis for 2TB cards.At Schneider Electric, I developed Acti 9 Smartlink gateway connected products for final distribution and LV panels using ZigBee and BLE technologies. I implemented antenna diversity, EEPROM mirroring, auto-discovery of wireless devices, Modbus TCP/IP, web server coding, and led the FDM 128 HMI project with access control security implementation.I am proficient in C, Python, C++, Shell scripting, RTOS, Linux Kernel, and networking concepts, with extensive experience across communication protocols (Modbus TCP/IP, Ethernet, SPI, I2C, UART, RS-485, Zigbee, BLE). I have conducted international on-site visits to Taiwan, US, Qingdao, and Shanghai for vendor collaboration. I am passionate about designing innovative embedded products, solving complex technical challenges, and actively participating in hackathons and innovation activities.
