About Ben

Hi, I'm Ben, a UI/UX designer with 4+ years of experience helping startups & scaleups create deeply functional user interfaces. I've worked on e-commerce, climate tech, and hospitality projects.

Key Credentials
=============
- 4+ years of professional experience in UI/UX design for e-commerce and sustainability.
- 1st Class Honours in Design Engineering (MEng) from Imperial College London.
- Founded & sold my own B2C product business (see below)

My background in engineering gives me the unique ability to understand what is feasible in terms of front-end development, while my experience starting my own company allows me to view design problems also as business opportunities that can help drive growth and revenue.

I'm particularly experienced in collaborating with startups and scale-ups in cross-functional teams. Having worked in startups my whole career, I'm very comfortable working with early-stage ideas and uncertainty.

How I Can Help
=============
- End-to-End Product Design: From initial concept to implementation hand-off, I’ll bring your mobile or web app to life.
- Usability Testing & UX Improvements: I’ll assess your existing interface and provide actionable recommendations to enhance the user experience.
- UI Touch-Ups: I can elevate your current design with a refined visual style and improved usability.
- User Research: I’ll help validate ideas for new products or features through in-depth user research.

Core Skills & Tools
===============
- Figma (UI design & prototyping)
- Responsive Design
- User Journeys/Flows
- User Research
- Usability Testing
- UX Analysis Reports
- Wireframing
- Style Guides & Design Systems

No matter what stage your project/idea is—whether it's a rough idea or a developed concept—I’d love to help bring it to the next level. Reach out, and let’s create something exceptional together!
