Project details

Overview

Design and production of a VTOL drone that switches between quadcopter and fixed-wing modes. Take-off and landing are handled vertically to broaden their location possibilities, once airborne it transitions to plane mode for a more efficient cruise, higher speeds and extended range. First flight was successfully completed in February 2026. All of it's specifications were validated during it's second test flight in july of 2026.

Key features / highlights

  • 3m Wingspan
  • 500g Payload
  • 4.1kg AUW (all-up weight)
  • 30 minute flight time

Project details

Overview

Differential drive mobile robot designed for autonomous navigation and obstacle avoidance using ROS2. The robot follows a two layer philosophy: the first, a lower layer comprised of a custom designed PCB handles low level control and perception whilst the second made of a raspberry pi manages more computationally heavy higher level functions. The robot is designed to be compact and efficient, whilst using well known hardware and software to focus on maintainability.

Key features / highlights

  • Encoder based odometry
  • Autonomous navigation using the NAV2 stack
  • Interruption and timing Management
  • Compact size

Tech & tools

  • ROS2 Jazzy
  • Gazebo
  • 3D Printing
  • Arduino IDE
  • C/C++
  • Python
  • OpenCV
  • Raspberry Pi
  • Proteus
  • JLC PCB
  • ATMEGA328P

My role

Designed the overall architecture and implemented the core functionality of the robot's control system.

Website code snippet.

Project details

Overview

Static portfolio website built to showcase my projects and serve as an extension to my resume hosted on my own domain. It allows visitors to learn more about me, my work, various projects, experiences and how to get in touch with me. The website is designed to be simple, clear and easy to maintain using modern web technologies such as HTML, CSS, and JavaScript. And depending on it's advancement focus on accessibility and usability across all devices (computer and smartphone).

Key features / highlights

  • Reusable templates across the entire site
  • Multiple media management (computers, smartphone ...)
  • Continuous integration workflow
  • FTP deployment to OVHcloud servers
