What I Work On

  • Embedded and IoT systems with ESP32, Raspberry Pi, Arduino, C/C++, and Python.
  • Robotics software for autonomous behavior, perception, control, and hardware integration.
  • Industrial automation workflows involving control panels, diagnostics, PLC logic, and maintenance systems.
  • Computer vision and AI-assisted tools using Python, OpenCV, PyTorch, and modern APIs.
  • Mechanical and mechatronics design using CAD, simulation, and prototype validation.

Featured Projects

A compact security monitoring stack for IoT labs. It ingests MQTT/TLS, Syslog, and CoAP/DTLS events, stores tamper-evident JSONL logs, and displays alerts through a local dashboard.

Focus: IoT security, Raspberry Pi, ESP32, MQTT, CoAP/DTLS, Python, embedded networking.

Receptionist Robot

An AI-powered receptionist robot combining speech interaction, autonomous navigation, real-time database connectivity, perception, embedded control, and hardware integration. The source is private, but the project is a major autonomous robotics milestone.

Focus: autonomous robotics, Python, OpenAI APIs, speech interaction, navigation, embedded systems, database integration.

An advanced 2-DOF precision-pointing mechanism project comparing compliant and non-compliant actuation architectures. It includes SolidWorks assemblies, STL/STEP manufacturing files, SimMechanics/Simscape models, MATLAB inverse kinematics and trajectory generation, MATLAB-to-Arduino serial control, stepper-motor firmware, ANSYS structural analysis, design drawings, reports, presentations, and a technical reference library.

Focus: compliant mechanisms, flexure-based motion, thruster pointing, precision mechatronics, structural validation, Simscape, SolidWorks, ANSYS, MATLAB, Arduino.

An end-to-end mechatronics build for a 3-DOF spherical parallel mechanism, including CAD design iterations, manufacturing files, PCB/Gerber assets, Arduino firmware, MATLAB inverse kinematics, torque-transmission analysis, ANSYS structural analysis, reports, poster, and presentations.

Focus: parallel robotics, kinematics, embedded servo control, PCB design, structural validation, SolidWorks/Inventor, ANSYS, MATLAB, Arduino.
