The strategic problem

The company enables GPs to unlock private equity data and route it to insight - real-time, granular, and investor-facing. But the product had a foundational gap: user needs were undefined, journeys were poorly structured, and no usability validation existed.

The surface problem was a confusing interface.

The real problem was that nobody had spoken to users yet - so any redesign would be redesigning assumptions, not reality. I made that case to the client and structured the engagement around research first, design second.

Why I pushed for discovery before any design work

The client's instinct was to start with screens. I reframed it as risk: without a validated user model, we'd be building on guesswork. A structured discovery phase would take longer upfront but prevent the far more expensive rework of shipping a product that users couldn't navigate. They agreed. That framing shaped the entire engagement.

Why build the design system before any screens

The faster path felt like designing screens directly. But screen-level work done without a shared component library creates a hidden cost: every component gets rebuilt from scratch, inconsistently. I proposed the system first — it added time upfront and saved a significant rework cycle later. The 100+ components we shipped became the foundation Phase 2 was built on without any reinvention.

Phase 1 - From chaos to clarity: discovery & design foundation

UX review & pain point mapping

Identified key accessibility and journey failures across the existing platform. Used these findings to define the scope of interview and testing work — not to jump to solutions.

User scripts for structured research

12 user interviews across two groups (MVP users + post-MVP). Informed the order bump structure, exclusive offers logic, and the checkout cross-sell approach.

User personas & journeys

Extensive wireframing based on research from workshops. Personas were grounded in actual LP types and private equity fund structures — not generic archetypes. Each journey mapped to a business scenario, not just a task.

Prototype for user interviews

Built a testable prototype early in Phase 2 to validate assumptions before committing to high-fidelity. This let us run structured user interviews and adjust core navigation decisions based on real behaviour, not intuition.


1st impact

The first phase established clear goals and built strong collaboration with the client, earning recognition letter. As a result, the business attracted more qualified leads and improved relationships with key stakeholders, paving the way for future expansion.

Atomic design system - 100+ components

Built using 'Atomic Design' principles - a unified component library spanning desktop and mobile. Modals, buttons, forms: all reusable and consistent, cutting future build time for designers and developers.

Before/after demonstrations

Created comparative examples to communicate design rationale to stakeholders. Gave the client a concrete language for discussing decisions and helped secure buy-in for Phase 2 investment.

High-fidelity designs

Dark-mode UI integrating complex data visualisation, optimised layouts, and mobile parity. Built on the Phase 1 design system — no reinvention, just application. Scalable patterns for the client's team to extend independently.

Investor presentation materials

Prepared the design assets the client used in their US funding presentation. Tight deadlines met through parallel workstreams - UI and presentation prep ran simultaneously.


Phase 2 moved from foundation-building to product definition. The brief expanded: the client needed not only a working platform, but materials that could be used to present to US investors — with a hard deadline.

I ran client workshops to gather insights into business strategy and LP expectations. We mapped the structure of private equity funds in detail, identifying distinct user types and roles, and used this to create an initial presentation for stakeholder alignment before any design work began.

What it delivered

Why prototype before high-fidelity?

The temptation in a deadline-driven project is to go straight to final designs. I pushed back: a mid-fidelity prototype took two days to build and saved us from a navigation model that early interview data showed was misaligned with how LPs actually think about fund data. That decision prevented a costly rework in the final sprint.

The high-fidelity designs delivered visually polished and user-friendly interfaces for the LP platform. By integrating insights from prototypes, we refined layouts, optimised data visualisations, and incorporated secure design practices. These designs laid the foundation for scalable features, ensuring a seamless user experience across desktop and mobile platforms.
