Evidence of how I solve problems—not just how I style screens.
Ten case studies spanning regulated onboarding, lending, transactional web, healthcare, travel tech, tourism, community, and campaigns.

Stanbic Customer Onboarding
Case study
A 17-screen regulated onboarding journey made progressive, legible, and reassuring.
17-screen journeyIdentity + document captureEditable final review
The challenge
Opening a bank account asks customers to make product choices, verify contact details, submit identity evidence, share personal information, and confirm everything accurately. The risk was a long, compliance-heavy process that felt opaque or overwhelming.
My approach
I broke the journey into clear commitments: choose an account, understand requirements, verify contact details, capture ID and signature, add preferences and personal data, then review editable sections before submission. Each screen asks for one meaningful decision and keeps progress focused.
The outcome
The concept demonstrates a complete onboarding path across individual, joint, and business account entry points, OTP verification, ID and KRA handling, next-of-kin and occupation data, selfie capture, review, and confirmation.

Stanbic Vehicle & Asset Finance
Case study
A 23-screen finance journey connecting discovery, application, fulfilment, and tracking.
23-screen service flowApplication + fulfilmentStatus + support states
The challenge
Vehicle finance stretches far beyond a single application form. Customers need to understand eligibility, register securely, provide asset and seller details, review costs, generate an offer, submit fulfilment documents, and follow progress after applying.
My approach
I designed the experience as one continuous service: a clear product landing page, registration and secure access, a loan dashboard, staged asset and seller forms, financial summaries, confirmation, document checklists, notifications, support, and a visible status tracker.
The outcome
The resulting concept covers the full relationship from first interest to release, giving customers context at every stage and giving delivery teams a structured map of the states, data, documents, and handoffs the service requires.
03 · Fintech · Mobile + USSD2025
Product design · UX/UI · Design system
Musoni Digital Lending
Case study
Complex loan journeys translated into a trustworthy, accessible mobile experience.
~57 mobile screensEnglish + KiswahiliAndroid, iOS + USSD
The challenge
The product had to explain loan logic without overwhelming customers and remain usable across different devices, languages, and levels of connectivity in Kenya.
My approach
I designed the Android and iOS experience alongside a USSD path, keeping the same mental model across both. Loan application, check-off loan, validation, error, and edge-case states were made explicit, with English and Kiswahili content considered from the start.
The outcome
The v1.0 package created a coherent product foundation for app and low-bandwidth use: a reusable visual system, complete core journeys, USSD wireframes, bilingual variants, and handoff-ready interaction states.
04 · Fintech · Web flow2024
UX/UI design · Responsive web · Transaction flow
Stanbic UPL Web
Case study
A short loan-linked payment journey with clear terms, confirmation, and completion.
Four-state web flowFinancial reviewClear success state
The challenge
The experience needed to connect a customer’s approved limit with a real purchase while making order reference, tenor, repayment date, cost, insurance, and terms understandable before commitment.
My approach
I kept the flow deliberately compact: enter the order ID, choose a repayment period and date, review the complete financial summary, accept terms, and receive a clear paid state. The layout keeps the active task visually dominant inside a broader banking interface.
The outcome
The four-state web concept gives customers a predictable path from eligibility to confirmation, reducing ambiguity at the points where financial commitment and transactional trust matter most.
05 · Healthcare · Website2025–26
Web design · Frontend · Digital strategy
Celestial Dental
Case study
A patient-first website that turns clinical trust into clear action.
Four branch journeysAppointment-first UXResponsive web system
The challenge
Dental care is personal and often urgent. The website needed to help families understand a wide service range, choose a nearby branch, and reach the care team without adding friction or anxiety.
My approach
I organised the experience around the questions patients ask first: Can I trust this clinic? Is the service I need available? Where can I visit? How quickly can I book? Clear service routes, branch context, social proof, and persistent appointment actions keep those answers close.
The outcome
The finished experience presents Celestial as a modern, approachable multi-branch practice. Appointment and WhatsApp paths remain prominent while service, safety, opening-hour, and location information build confidence before the first visit.
06 · Community · Website2026
Website design · Information architecture · Frontend
GracePoint Thika Road
Case study
A welcoming digital home for first-time visitors and the church community.
Visitor-first navigationSermon + event discoveryResponsive content system
The challenge
A church website serves two audiences at once: people deciding whether to visit and members returning for sermons, events, gatherings, counselling, and giving. Both groups needed to find the right next step quickly.
My approach
I shaped the navigation around real participation rather than internal structure. A distinctive, message-led hero establishes GracePoint’s identity, while visit and location actions sit alongside direct access to sermons, gatherings, events, counselling, and community stories.
The outcome
The result is a warm, media-rich church hub that helps a newcomer plan a Sunday and gives the wider congregation one dependable place to reconnect with teaching and church life.
07 · Education + tourism2024–26
IT lead · UX/UI · Web development
Foundations of Tourism
Case study
A digital platform connecting tourism education to real-world opportunity.
Tours + journalStudent pathwaysPartner journeys
The challenge
FoTI needed to speak clearly to students, universities, tourism partners, and travellers while showing how hands-on learning, tour experiences, research, and career development belong to one ecosystem.
My approach
I centred the story on a direct promise—learn by doing, earn by creating—then separated key journeys for tours, journal content, students, careers, and partners. The interface balances institutional credibility with the energy of travel and enterprise.
The outcome
The website gives FoTI a focused digital front door: prospective students can understand the model, partners can see how to participate, and visitors can move from the mission into real tours and stories.

FoTI Tours
Case study
A student-led tourism marketplace where academic research becomes a bookable experience—and a career path.
Three role-based journeysM-Pesa booking flowResearch + approval system
The challenge
FoTI Tours serves three connected audiences with very different needs. Travelers need discovery, trust, booking, communication, and payment; students need tools to create tours, prove their research, manage bookings, and earn; lecturers need a dependable approval and quality-control workflow.
My approach
I designed the product as a role-based service ecosystem. Travelers move from destination discovery into verified tour detail, booking, M-Pesa payment, messaging, and reviews. Student guides use a five-step tour builder with itinerary, pricing, documentary, and academic-publication requirements. Lecturer approval keeps every live experience academically grounded.
The outcome
The v1.0 React Native product connects traveler, student, lecturer, and administrator journeys in one marketplace. Firebase supports real-time profiles, listings, bookings, messages, and approvals, while the student dashboard connects earnings and fieldwork to FoTI’s wider career pathway.

BCB Onboarding
Case study
A structured mobile onboarding flow designed to make every next step feel obvious.
Multi-step onboardingReusable form patternsPrototype-ready flow
The challenge
Multi-step onboarding can quickly become dense: identity details, verification, forms, feedback, and exceptions all compete for attention. The flow needed to preserve trust while keeping progress visible.
My approach
I used progressive disclosure, focused screens, clear completion cues, and consistent form patterns. Happy paths and recovery states were mapped as one connected journey so the interface could support momentum without hiding important requirements.
The outcome
The work produced a coherent, prototype-ready mobile flow with reusable interaction patterns and a clear screen map—giving product and engineering teams a more dependable foundation for implementation.

Stellar HR Recruitment Campaign
Case study
A social campaign that turns recruitment support into an immediate, memorable offer.
Two campaign routesBilingual messagingDirect-response CTA
The challenge
Recruitment services are process-heavy, but social audiences decide in seconds. The campaign needed to explain the value to employers quickly, feel recognisably Kenyan, and make the phone response path impossible to miss.
My approach
I combined bold brand orange, human expressions, short service checklists, and high-contrast calls to action. The second route uses bilingual English and Kiswahili copy to add familiarity while keeping sourcing, screening, checks, and onboarding clear.
The outcome
The two coordinated creatives give Stellar HR a flexible campaign system for direct-response social posts: one process-led route and one conversational route, both designed around a clear contact action.
