About The Project
Platform: Web-app & Mobile-app
Role: Lead UX/UI Designer for Southeast Asian Countries
Duration: 2019 - 2021
———————
Project Overview
Mercedes-Benz Financial Services (MBFS) identified a growing need to modernize its after-sale experience for customers who financed their vehicles. The existing post-purchase experience was fragmented, paper-based, and inconsistent across channels. Our mission was to design an intuitive, scalable, and secure digital platform (web-app and mobile-app) that offers customers the ability to manage their contracts, payments, renewals, and support their needs efficiently and independently.
As the Lead UX/UI Designer, I spearheaded the end-to-end design process - from research and conceptualization to stakeholder alignment, prototyping, and final design handoff - navigating a complex enterprise ecosystem to deliver a product that balanced user needs with strict corporate, legal, and technical constraints.

Objectives
Create a unified digital interface for MB-financed customers post-vehicle purchase.
Enable customers to:
View and manage active contracts
Make one-time or recurring payments
Initiate and complete contract renewals
Contact customer support and track support ticket status
Receive relevant notifications and updates
Key Challenges
Internal Challenges
Bureaucratic complexity: Decision-making within the corporate structure involved multiple layers of approvals, which slowed design iteration and implementation.
Legacy systems: The digital infrastructure was built on outdated backend technologies and inflexible data models, making design innovation difficult.
Siloed departments: Each team used different design libraries, component systems, and documentation formats, leading to inconsistency and fragmentation.
Restricted user access: Due to the confidentiality of financial data and strict NDAs, we had limited ability to conduct user research, usability tests, or gather direct feedback.
External Challenges
Brand governance: Mercedes-Benz brand partners had strict brand identity rules and minimal involvement in UX decision-making, limiting creative freedom.
Strategy volatility: Frequent shifts in corporate digital and product strategy caused confusion and disrupted the team’s ability to maintain focus and momentum.
Design Approach
1. Discovery & Research (within constraints)
Despite the lack of access to real users, we conducted:
Stakeholder interviews across departments (product, support, finance, legal) to understand user pain points indirectly.
Internal usability audits of legacy systems and customer-facing portals.
Data analysis of support ticket logs and CRM systems to identify frequent customer issues and tasks.
We also referenced indirect benchmarks from other high-end automotive and fintech experiences to define expectations.
2. Problem Framing
From the research, we defined key pain points:
Customers were unaware of contract status or deadlines.
Payment processes were cumbersome, often requiring physical interaction.
Renewing contracts was complex and lacked clear guidance.
Support access was slow and inconsistent.
These insights shaped our design principles:
Transparency: Visual clarity of contract status, payment history, and next steps.
Simplicity: Reduce cognitive load by guiding users through complex financial actions.
Empowerment: Give users full control over their post-purchase experience, asynchronously and remotely.
Key Features Designed
Customer Dashboard
A centralized hub offering:
Active contract overviews with real-time status indicators.
Visual summaries of monthly payments, deadlines, and contract milestones.
Notifications and important updates (e.g. renewal eligibility, overdue alerts).
Payments Center
Support for one-time payments, scheduled payments, and installment views.
Secure integration with payment gateways (compliant with Mercedes-Benz and financial regulations).
Receipts and transaction history available for download.
Contract Renewal Flow
Simplified multi-step renewal wizard.

Digital consent and e-signature capability integration.
Customer Support Portal
Open and manage support tickets by category (billing, contracts, technical).
In-app ticket status tracking and agent communication threads.
Knowledge base and quick-help section for self-service.
Design System & Collaboration
To bridge the gap between siloed design efforts:
I audited all internal design libraries, identified redundancies, and collaborated with other designers to standardize a scalable UI component system.
Advocated for an internal cross-functional design guild, enabling knowledge sharing between siloed departments.
Defined documentation standards and Figma libraries to align with Mercedes-Benz’s corporate design language.
Stakeholder Management
Working in such a layered organization required strong stakeholder facilitation. I:
Conducted regular design walkthroughs with product managers, IT, and senior executives.
Created prototype-driven storytelling decks to illustrate concepts clearly and reduce ambiguity during reviews.
Navigated legal and compliance reviews by creating design exception reports to rationalize user-first design decisions.
My Role & Responsibilities
As Lead UX/UI Designer for Southeast Asian Countries, I was responsible for:
Leading design strategy, research, and execution focusing on SEA markets.
Working closely with other fellow designers from MB HQ, MB USA, MB Europe, MB China to keep design and branded content consistent.
Translating ambiguous requirements into actionable user flows and interfaces.
Managing stakeholder relationships across departments and external brand partners.
Establishing design standards and promoting cross-team alignment.
Delivering final prototypes and design specs to the development team.
