KEY CONTRIBUTIONS

  • Designed the full product experience for DEX, including search flows, catalogue structure, metadata hierarchy, and community features

  • Drove research with Whole of Government (WOG) officers, synthesising insights into actionable archetypes and UX priorities

  • Crafted and optimised AI prompt engineering for guided search

  • Collaborated with a DBA team member to translate designs on Lovable.dev

  • Spearheaded a 3-day MVP pivot, including discovering that Lovable could rebuild UI with ~98% accuracy when fed PNG mockups + structured prompts

  • Delivered a working MVP for mid-hackathon validation, accelerating stakeholder buy-in and incubation

Rapid MVP Pivot (Hackathon Build)

We initially explored building the MVP on Outsystems, but development velocity was not keeping pace with the design direction. With only 3 days left before the mid-hackathon Feedback Bazaar, we needed a faster way to prototype.

My DBA/Engineer teammate rebuilt our flows in Lovable.dev while I refined the prompt engineering behind the AI-guided search. On the final day, we discovered that Lovable could generate interfaces even more accurately when we uploaded PNGs of my designs together with structured prompts — allowing us to match ~98% of the intended experience.

Through tight collaboration, experimentation, and extended hours, we delivered a functional MVP in time for the feedback session, giving us early validation two weeks before the finale.

Context

There was no central source of truth for WOG digital products. Officers relied on memory, scattered links, old documents, and spreadsheets - leading to duplicated ideas, prolonged search times, and stalled execution.

During a preliminary research, these pain points were discovered:


83% of officers rely on ad-hoc discovery methods, and satisfaction with current search approaches averaged only 2.8/5.

Users highlighted these as key blockers:

Fragmented Documentation

Low Awareness.png

Low Awareness of Existing Solutions

Delay.png

Delays from difficulty engaging product teams

Problem Statement

This surfaced a broader issue across the Whole-of-Government:

WOG officers need an easy way to discover and understand existing digital solutions, but fragmented information hinders discoverability and reusability. This leads to prolonged search times and impacts timelines.

To address this, we set out to create a one-stop, searchable, AI-guided platform that brings together all WOG digital products — making discovery faster, collaboration easier, and decision-making more informed.

AI & BETTER SEARCH AS TIME-SAVERS

Finding

~70% rated an AI chat tool as highly valuable for refining problem statements and improving search accuracy.

Impact

AI-guided search can reduce search time and make results more relevant.

ProductInfo.png

NEED FOR RICHER PRODUCT INFO.

Finding

75%+ want detailed product pages (tech specs, roadmaps, team, adoption metrics).

Impact

Transparent product info helps officers quickly assess fit and viability.

Community.png

COMMUNITY FEATURES MATTER

Finding

~85% see commenting, voting, and feedback as essential; strong support for peer-driven validation.

Impact

Community tools help validate quality, share real use cases, and drive continuous improvement.

Direct Access.png

DIRECT ACCESS TO PRODUCT TEAMS

Officers often struggle to find or reach product owners, and want clearer contact points or simple ways to ask questions.

Impact

Direct engagement (Q&A, comments, discussions) speeds up evaluation and builds trust across agencies.

Incentive.png

INCENTIVES DRIVE CONTRIBUTION

Finding

~65% say incentives (badges, leaderboards, recognition) would motivate them to contribute regularly.

Impact

Thoughtful gamification can sustain engagement and keep the repository up to date.

Impact & Outcomes

BEFORE

  • No central repository

  • Reliance on memory/ scattered documents

  • Hard to compare tools

  • No clear way to reach product teams

  • Inconsistent discovery workflows

AFTER

  • One-stop platform

  • AI-guided search

  • Interactive product catalogue

  • Rich product detail pages

  • Discussions, upvotes, and team visibility

  • Discovery time reduced from days → minutes

📉 80% REDUCTION IN DISCOVERY TIME

Search time went from 5.2 days → minutes, enabling officers to make faster, better-informed decisions across agencies.

👍 100% POSITIVE PROTOTYPE VALIDATION

All officers who tested the prototype said they would use DEX, citing improved clarity, speed, and confidence in evaluating tools.

📈 INCREASED VISIBILITY OF WOG PRODUCTS

Officers reported that DEX made it significantly easier to:

  • understand what already exists

  • compare available tools

  • identify the correct product team - this directly supports better reuse of digital solutions.

🤝 STRENGTHENED CROSS-AGENCY COLLABORATION

Features like discussions, comments, and upvotes made it easier for officers to learn from one another and surface real use cases — reducing silos across WOG.

🚀 EARLY MOMENTUM FOR INCUBATION

The strong validation and clear demand enabled the project to progress into a 6-month incubation backed by leadership support.

Key Takeaways

VALIDATE EARLY TO MOVE FAST

Rapid testing gave us clarity on priorities and reduced guesswork, enabling confident decisions under extreme time pressure.

PIVOTING IS STRATEGIC, NOT RISKY

Switching from Outsystems to Lovable showed that choosing the tool that gets you closest to outcomes is sometimes the smartest product decision.

GOOD IDEAS NEED STRONG SPONSORSHIP

Community tools only succeed when leadership alignment is secured early; organisational buy-in is as critical as UX design.

LEADERSHIP IS INITIATIVE, NOT HIERARCHY

I contributed the initial idea and partnered with colleagues across divisions to bring it to life. The experience showed me how influence can come from collaboration, not position.

MOMENTUM IS A DESIGN ENABLER

Clear direction, positive reinforcement, and focused collaboration helped the team deliver efficiently and avoid unproductive cycles.

TECHNICAL CURIOSITY EXPANDS CAPABILITY

Experimenting with prompt engineering and PNG-to-UI generation strengthened my ability to bridge design and engineering quickly.
