View my CV

2026 - Now

I recently joined HeadBox as their sole Product Designer, with a focus on AI-powered B2B SaaS platforms.

2022 - 2026

I owned end-to-end design and acted as a bridge between product, commercial, and engineering teams, ensuring business goals were met while championing inclusive design.

2020

I enabled the team to demonstrate feasibility to clients by developing simulations for three robotic logistics cell concepts. I also redesigned the core sales deck, driving client acquisition.

I have a background in user-centred design and engineering, and thrive in cross-functional environments.

2017 - 2021

My course followed a hands-on approach on the design process, user research, user testing, and design psychology.
