About Me

A Decade Of Turning Complex Problems Into Simple Products.

I'm Dinuka — a Senior UI/UX Designer with 10+ years shipping products across fintech, SaaS, healthcare, and enterprise. I start with the problem, not the pixels: deep research, rapid iteration, and accessibility as a baseline — design that scales through systems and gets out of the user's way.

How I Work

My Design Process

A human-centered approach, enhanced by AI, to deliver exceptional digital experiences.

Step 01

Discovery

I align with stakeholders, understand the business context, and define the right problems to solve — before a single pixel is drawn.

Key Activities
Stakeholder Workshops

Collaborate with key stakeholders to align on goals and expectations.

Requirements Gathering

Collect and document business, user, and technical requirements.

Business Goals

Define measurable goals and success criteria for the product.

Success Metrics

Interviews, analytics, and competitive audits to understand real user needs and where the current experience falls short.

Key Activities
User Interviews

Talk to real users to uncover needs, motivations, and pain points.

Competitive Audit

Benchmark rivals to find gaps and opportunities worth chasing.

Analytics Review

Read behavioural data to see where users struggle and drop off.

Persona Mapping

Synthesise research into clear, actionable user archetypes.

Step 03

Ideation

Sketching broadly with the team — How-Might-We framing, Crazy 8s, and honest critique to converge on the strongest direction.

Key Activities
How-Might-We

Reframe problems into opportunities the whole team can rally on.

Concept Sketching

Explore many rough directions fast before committing to one.

Crazy 8s

Time-boxed divergent sketching to push past the obvious ideas.

Team Critique

Pressure-test concepts together with structured, honest feedback.

Step 04

Wireframes

Low-fidelity flows that nail structure and hierarchy fast, so we argue about the right things while change is still cheap.

Key Activities
User Flows

Map the paths users take through each core task and screen.

Information Architecture

Structure content and navigation so people find what they need.

Low-Fi Layouts

Block out hierarchy and grids before visual polish enters.

Content Structure

Draft real copy and states so layouts hold up in reality.

Step 05

Prototype

High-fidelity, clickable prototypes that feel real enough to test — motion, states, and edge cases included.

Key Activities
Hi-Fi Screens

Craft polished, pixel-accurate visual design and detail.

Interaction Design

Define how every control responds, from tap to transition.

Motion & States

Design loading, empty, error, and success states with motion.

Clickable Flows

Wire screens into flows that testers can actually use.

Step 06

Testing

Moderated usability sessions and A/B tests to validate decisions with evidence, not opinions.

Key Activities
Usability Sessions

Watch real users complete tasks to expose friction early.

A/B Testing

Compare variants with live traffic to settle debates with data.

Task Analysis

Measure success, time, and error rates against clear benchmarks.

Findings Synthesis

Turn raw observations into prioritised, shippable insights.

Step 07

Design System

Tokens, components, and documentation so what ships stays consistent — and the next feature ships faster.

Key Activities
Design Tokens

Codify colour, type, and spacing as a single source of truth.

Component Library

Build reusable, accessible components teams can trust.

Usage Docs

Document how and when to use every pattern and component.

Governance

Set contribution and review rules that keep the system healthy.

Step 08

Launch

Close partnership with engineering through handoff and QA, then post-launch metrics to keep improving what shipped.

Key Activities
Dev Handoff

Hand engineering clean specs, assets, and living documentation.

Design QA

Review builds against the design to catch drift before release.

Release Support

Stay close through rollout to resolve edge cases fast.

Post-Launch Metrics

Track real-world impact and feed learnings into the next cycle.
