Product Designer focused on systems, complex workflows, and shipped outcomes

I design and build complex digital products that help real users solve high-stakes, operational problems—particularly in enterprise and data-heavy environments.

My work sits at the intersection of product thinking, systems design, and hands-on execution. I’m most interested in shaping how entire workflows function end-to-end, not just refining individual screens.

Over the past few years, I’ve worked across product areas including design systems, enterprise costing and estimating tools, mobile and desktop workflows, and data reporting platforms. Much of this work has involved navigating ambiguous requirements, evolving legacy systems, and translating complex business logic into usable, scalable product experiences.

Previous Work

Bolster Systems app interface

1Bolster Plus — Enterprise Costing & Operational Platform

Led design across a major multi-part product initiative spanning costing, estimating, timesheets, reporting, and project workflows. Defined flexible system architecture to support highly variable client processes, working closely with engineering and stakeholders to deliver a unified platform for operational and financial visibility.

2Document Library — End-to-end feature ownership

Owned design delivery for a cross-platform feature spanning desktop and mobile. Responsible for UX, UI, and parts of frontend implementation, ensuring the system aligned with both user workflows and internal data structures.

3OSCIL-8R — Interactive desktop music visualiser (personal project)

A fully designed and built Tauri desktop application exploring real-time audio visualisation and generative motion systems. This project combines product design, interaction design, and engineering into a single independent build.

Bolster Systems app interface

4Design System — Foundations for scalable product development

Built and introduced a design system from the ground up to improve consistency, accelerate delivery, and create shared structure across a growing product ecosystem. Worked directly with engineering to ensure implementation feasibility and long-term maintainability.

About Me

How I Work

I focus on understanding the underlying system before designing solutions. That usually means spending more time on structure, constraints, and workflows than on surface-level UI decisions.

I’m comfortable working in environments where:

  • Requirements evolve
  • Systems are partially legacy
  • Multiple stakeholders influence direction
  • Design needs to align closely with engineering reality

My goal is always the same: to turn complexity into something coherent, usable, and scalable.
