I design complex B2B products and systems, connecting product direction, design quality and AI-assisted prototyping.
An interactive prototype to make product configuration visible in real time.
Redesigning a real-time rules engine without losing the flexibility that made it valuable.
Building the shared foundations behind very different B2B products.
I grew from Junior to Lead at GiG, taking on broader responsibility for product quality, systems and team direction. That mix of product judgement, craft and leadership shapes how I work today.

“In his role as Senior Product Designer and eventually as team Lead, he played a key part in driving product design initiatives and improving the overall user experience across our backoffice platforms.”
Small projects built with AI.
A different space to explore and make.

Ternside, experiment 1 of 4.
Five practical questions about the work, the team and what I’m looking for next.
I start by making the problem smaller and clearer: understanding the users, the business context, the technical constraints and what we actually know.
From there, I explore flows and interactions, prototype when it helps us learn faster, and work closely with Product and Engineering through implementation.
I don’t follow a fixed process. I use the level of research, exploration and fidelity the problem needs.
I try to find the best balance between user needs, business goals and what is technically realistic.
That means understanding why each constraint exists, making the options visible and being clear about what we gain or lose with each decision.
I’d rather make a conscious compromise than design an ideal solution that cannot ship.
It depends on the evidence available.
I use user and stakeholder feedback, usability findings, product behaviour and metrics when they are available, then keep learning after implementation.
I care about whether the product became easier and more effective to use — not just whether the final UI looks better.
Leading design has changed how I think about impact in a team.
Beyond my own design work, I enjoy giving clear feedback, mentoring designers, improving shared patterns and systems, and helping maintain a consistent quality bar.
I’m comfortable moving between product detail and team-level decisions depending on what the work needs.
I’m looking for a Senior Product Designer role where I can shape complex products hands-on and raise design quality.
I’m especially interested in B2B products and complex platforms, working closely with Product and Engineering.
My Lead experience adds mentoring, clear feedback and a systems perspective to the hands-on product design I bring to a team.
