Manoj Kumar Selvaraj

37degrees, Inc, Chicago

Lead Embedded & Firmware Development Intern

• Led full lifecycle embedded development for the CultureON portable incubator, taking the system from early concept through EVT → DVT → PVT and delivering pilot-ready hardware and firmware.
• Architected the hardware platform, including sensor/actuator selection, power-tree design, protection circuitry, and interfaces; designed 5 custom PCBs and assembled five production-quality units.
• Integrated the TPS25947 power switch to replace diode-based muxing, improving overall power efficiency by ~15% for continuous-duty operation.
• Developed production-grade firmware using FreeRTOS, implementing multi-task scheduling, inter-task messaging, and sensor fusion with deterministic control of actuators.
• Implemented the connectivity stack, including custom BLE GATT services for mobile/desktop integration and Wi-Fi station mode + MQTT telemetry for secure cloud-based data streaming.
• Built a reliable OTA update pipeline with image validation, rollback capability, and version control for remote firmware deployment.
• Developed manufacturing test firmware and automation scripts, reducing board bring-up and verification time from ~2 hrs → ~30 mins per unit.

YantraVision Software Pvt Ltd, Bangalore

Senior Software Engineer

Client [Xilinx-AMD] : Multicore DSP Kernel Optimization & Validation (Hardware Accelerator, HPC, FPGA)

• Accelerated and benchmarked DSP libraries (GeMM, 2D-FFT) on FPGA (Versal ACAP) and AIE SIMD processors using Xilinx Vitis, documenting detailed performance metrics.
• Optimized a 4096-point FFT on AI Engine by reducing data-transfer bottlenecks, achieving 1.5× MSPS speedup over the baseline HLS kernel.
• Established a Jenkins-based CI/CD regression suite, automating functional and performance testing for 72+ DSP libraries.
• Designed and validated single- and multi-core kernels for AIE; performed pre-silicon validation (QEMU) and post-silicon bring-up including power characterization.
• Spearheaded a three-member team to develop a multithreaded host application on ARM Cortex-A72, reducing 5G FR2 signal-processing latency by 75%.
• Integrated Linux kernel driver interfaces (XOCL) with XRT APIs for efficient interrupt handling and inter-process communication between the host and FPGA.

Machine Vision Systems & High-speed Imaging for Carton Printing (Computer Vision, Real-Time Processing)

• Implemented GPU acceleration using CUDA and OpenMP, maintaining inspection throughput at 300–350 meters per minute while improving computational efficiency.
• Engineered automated workflows for annotating 40,000+ Braille points on medical packaging, achieving 94.8% detection accuracy at 50 FPS.
• Enhanced Braille inspection speed using Haar Cascade classifiers, achieving ~5 ms processing time per carton with improved defect-detection reliability.
• Developed robust image-processing pipelines using dark-field illumination to detect embossing defects and ensure consistent print-quality inspection.
