What I work on

Software, AI & Security

  • Deep-learning segmentation and computer vision
  • Hardware-security research on CNN accelerators
  • SIEM monitoring, threat hunting and MITRE ATT&CK detections

Electronics & Embedded

  • RTL design in Verilog, FPGA and digital arithmetic
  • AMBA AHB/APB bus design and approximate FP16/BF16 multipliers
  • Edge AI and sensor fusion on Raspberry Pi: INT8 ONNX YOLO, GPS tagging and LoRa links

Featured repositories

  • ICE_KATTI_GLOF_Challenge — glacial lake segmentation from satellite imagery with U-Net++ and an EfficientNet-B3 encoder in PyTorch, a hybrid Focal + Dice + Boundary loss and test-time augmentation. 4th place, GLOFeagles'26.
  • Edge_AI_Based_Road_Anomaly_Detection_using_raspberrypi — real-time pothole and obstacle detection on a Raspberry Pi using an INT8-quantized ONNX YOLO model on CPU, with GPS tagging and event-based logging.
  • file-change-tracker — lightweight Linux file-integrity monitor in Go with SHA-256 baselines, an admin-approval workflow and a systemd service.

Also working on

  • Security analysis of a CNN accelerator: a hardware Trojan in a LeNet-5 FPGA design, a defense bypass and a stronger trigger (Artix-7, <1.1% LUT/register overhead)
  • AHB-to-APB bridge in Verilog with a three-state controller FSM
