SCOPE OF OWNERSHIP

First designer on the product team.
No system. No process. No library.

As the first and lead designer in a 4-person product pod, I designed the complete user experience across all five product surfaces — from the merchant POS to the consumer loyalty app — delivering high-fidelity prototypes, a token-based design system, and interaction logic that engineering built directly from. Field research at partner venues was my primary method: peak-hour observation translated into measurable reductions in onboarding time, support tickets, and End-of-Day (EOD) reconciliation effort.

I owned the complete UX architecture across five core product surfaces: Bridge Mobile Point-of-Sale (MPOS), Partner Backend, Kitchen Display System (KDS), QR Ordering, and the Elite consumer app. I translated the extreme operational complexity of high-volume restaurants into highly scalable, cohesive digital workflows.

I conducted deep contextual field visits implementation shadowing and peak hour observation at partner venues. This research was not a design phase it was the strategic foundation used to strictly measure and reduce the cognitive load our interfaces imposed during live service.

I produced high-fidelity prototypes, comprehensive user flows, and cohort maps that closed the gap between product requirements and the engineering source of truth. I embedded complex operational rules — dynamic discount logic, tax calculations, and pricing tiers — directly into the design architecture so engineering built from specification, not interpretation.

I built a scalable component library using a token-based architecture from a blank canvas. This became the definitive visual and interaction language across all five core product surfaces, fundamentally accelerating engineering velocity and enabling rapid platform scaling across new restaurant partners.

THE STAKES

Three compounding failures
that defined the design brief.

Follow the money through a scaling venue's operations. Revenue enters healthy — then leaks at three joints. None is individually fatal. At volume, the combination is.

Revenue in · Live service
fragile margin · What survives
PLATFORM CEILING:

The Version 1 system hit a hard ceiling against enterprise requirements. Scaling to major metros demanded a comprehensive financial operating system — not a basic POS with a menu bolted on. I defined the scope gap and drove the case for the V2 platform architecture.

RESEARCH FOUNDATION

Field research was not a phase.
It was the foundation.

Four parallel research tracks ran before a single screen was designed — embedded with post-sales and implementation teams, observing live onboarding at partner venues.

DESIGN PRINCIPLE — EMERGED FROM FIELD RESEARCH

In a high-pressure hospitality environment, the interface that demands the least attention wins. I designed around that constraint from the first frame — every additional tap is a direct training cost and a live service risk.

Core system layers.
Built from the operational floor up.

THE OPERATIONAL CORE

Bridge & Mobile POS (MPOS) Architecture

Transformed desktop and Mobile Point-of-Sale (MPOS) systems to proactively guide staff. Shifted the interface from static data entry to a predictive visual first engine to accelerate service delivery.

Cognitive Offloading (MPOS): Replaced dense data-entry screens with visual-first order flows — cutting training overhead and eliminating the hesitation errors that spiked during peak service.
Predictive State Transitions: Designed context-aware prompts that surface the correct next action automatically — removing decision paralysis at the moments that slow a live service down.
Live Action Centre (Bridge): Built a spatial floor plan view unifying all order channels — walk-in, QR, and MPOS — with live alerts that let managers intervene before a problem became a complaint.
Reduced staff onboarding time
Consumer Acquisition Pipeline

QR Digital Dine-in

Eliminated service bottlenecks by enabling instant frictionless ordering. Built an acquisition pipeline that captures impulse revenue without requiring an initial app download.

Frictionless Ordering: Designed instant browser-based ordering with zero app download required — capturing impulse spend the moment a guest sat down, bypassing floor service queues entirely.
Real-Time Ping: Gave guests a direct service request button from their browser — cutting wait times at the table and removing the waiter as a bottleneck for common requests.
Acquisition Nudges: Embedded discount triggers at the bill moment — converting one-time QR diners into Elite app users at the highest-intent point in the customer journey.
Increased table turnover velocity
The Consumer Growth Engine

Elite B2C App

Engineered a unified consumer platform designed to drive high margin footfall, increase average order value, and build long term customer loyalty.

Elite Tier Discount Engine: Designed a dynamic AOV-threshold reward system that surfaced personalised discounts as cart value climbed — directly driving the 35% merchant revenue lift.
The Conversion Loop: Aggregated diner demand data across the app to surface high-performing independent venues — converting top venues into enterprise platform clients through demand-led evidence.
Lifetime Value Engine: Designed subscription and loyalty mechanics that rewarded repeat visits — shifting diner behaviour from occasion-based to habitual and compounding customer LTV over time.
35% merchant revenue lift
AUTONOMOUS CORE OS

Partner Backend Part 1

Designed a decentralised operating system that gives local teams full operational independence — covering franchise onboarding, daily workflows, and large-scale event logistics without requiring central IT support on every action.

The Complete OS: Architected an enterprise-grade platform interface from zero — covering franchise onboarding, system governance, and large-scale operational workflows across production and event logistics in a single unified surface.
Business-to-Business (B2B) Supply Chain & Vendors: Integrated automated supplier management and seamless Purchase Order creation alongside split Goods Receipt Note (GRN) workflows to optimise backend efficiency.
Maker-Checker Protocol: Built a mandatory dual-approval flow for all high-value modifications — protecting margins against accidental pricing errors and preventing unauthorised discount changes from leaking through undetected.
40% Drop in Support Calls
50% Faster Onboarding
THE MARGIN DEFENCE LAYER

Partner Backend Part 2

Designed automated accounting and inventory workflows that eliminated manual data entry, secured profit margins at the ingredient level, and connected back-of-house procurement directly to front-of-house revenue reporting.

Recipe-Backed Diminishing Inventory: Designed real-time variance reporting tied directly to recipe yields — flagging waste and pilferage at the point of pour, not at end-of-shift when it was too late to act.
Master SKU Architecture: Designed a hierarchical stock unit structure handling complex combos, modifiers, and shared ingredients — generating the granular margin reports that made the 90% EOD reduction possible.
Multi-Owner Payout Routing: Automated daily settlement across equity stakes — replacing the nightly manual calculation that introduced human error, and cutting End-of-Day (EOD) reconciliation effort by 90%.
90% reduction in EOD reconciliation effort
OPERATIONAL HARDWARE

Additional Systems

Designed the operational hardware layer — FOH event entry and KDS — to handle high-traffic edge cases and physically demanding environments without service interruption.

Front of House (FOH): Designed the event entry experience — secure digital ticket purchasing and rapid QR scanning that kept guest queues moving and removed cash-handling bottlenecks at the door.
Kitchen Display System (KDS): Designed intelligent Kitchen Order Ticket (KOT) routing to the correct preparation station — eliminating the shouted-order system and ensuring simultaneous execution of complex multi-station tickets.
