About Me
Background
I'm a 3rd year Aerospace Engineering student at the University of Sheffield, on track for a first-class masters degree. I enjoy working on projects that combine practical problem-solving with creativity from turbojet engines to simulations and games.
I have a strong foundation in engineering principles, programming, and design, with a particular interest in propulsion systems. I hope to be able to apply my skills and experience in a real-world setting, where I can contribute to innovative projects and learn from experienced professionals.
What I Do
I prototype and attempt to develop full-stack solutions and systems with hands-on experience in:
- π Propulsion system R&D and aircraft design
- π§ Real-time digital signal processing and audio systems
- πΉοΈ Various games and mini-games, including some game jams
- π Full-stack web development, from design to deployment
- π§ Machine learning and AI, including neural networks
Whatβs Next?
Iβm currently open to internships, freelance work, or collaborative projects. Particularly those related to product design, simulation, or software that blends technical depth with user-focused design. I'm based in Sheffield and Nottingham and happy to work locally or remotely.
Long term, I'm hoping to launch my own tech/engineering company focused on future-facing, meaningful design. Until then, I'm building towards that vision one system at a time.
