⚡ Engineering Summary

role: "IoT, Embedded Firmware & Robotics Engineer"
education: "B.Sc. in IoT and Robotics Engineering — University of Frontier Technology, Bangladesh (UFTB)"
core_focus:
  - "Deterministic RTOS firmware & concurrent embedded state machines (ESP32-S3 / C++)"
  - "Physical sensor fusion, on-chip vibration FFT DSP & RF Channel State Information (CSI)"
  - "Autonomous mobile robotics with ROS Navigation & differential drive kinematics"
  - "Edge machine learning deployment on resource-constrained microcontrollers"
toolchain: "C/C++, FreeRTOS, ESP-IDF, Python, PyTorch, ROS, Altium Designer, EasyEDA, Linux"

I build systems that bridge physical hardware and intelligence — from schematic capture and multi-layer PCB routing to deterministic real-time firmware, digital signal processing, and low-latency cloud telemetry.

🚀 Featured Engineering Projects

🛰️ 1. Edge Sensing & Digital Twin Systems

 

  • Bridge Structural Health Monitoring (SHM): Low-cost IoT structural monitoring using ESP32-S3 + MPU9250 MEMS. Performs real-time 1024-point on-chip FFT vibration spectrum analysis, predictive micro-crack alerting, and renders an interactive 3D digital twin dashboard.
  • Wi-Fi CSI Indoor Localization: 100% privacy-preserving human presence localization using ESP32-S3 56-subcarrier OFDM RF sensing. Features Hampel & Butterworth filtering, Doppler feature extraction, Random Forest classification, and 2D Kalman Filter state estimation.

⚡ 2. Safety-Critical RTOS & Bio-Telemetry Devices

 

  • RTOS Railway Level Crossing Platform: Deterministic FreeRTOS implementation across dual-core ESP32-S3 with 6 prioritized concurrent tasks. Eliminates race conditions via atomic queues and enforces a fail-safe FSM gate control with dual-sensor obstacle validation. (Accepted at ECCT 2026 / Taylor & Francis)
  • SmartSpiro IoT Spirometer: Award-winning (ImpactX 2026 Finalist) clinical screening spirometer utilizing differential pressure sensing and on-device machine learning for early respiratory pattern classification (FVC, FEV1, PEF).

🤖 3. Autonomous Robotics & Applied AI

 

  • AgroBot Autonomous Rover: Field-deployable agricultural robot combining ROS move_base autonomous row navigation with an ESP32 differential drive controller, RS485 7-in-1 NPK soil telemetry, and precision spot irrigation actuation.
  • Multimodal AI Video Summarizer: High-performance video intelligence pipeline using Faster-Whisper (CTranslate2 int8) for 4–5× accelerated speech-to-text, BART abstractive summarization, and cross-platform native execution.
