Case Study 01
OnePlusOne — Bank transaction flow
2025 · Fintech · Mobile
The problem
Users trusted the bank, but not the app.
Transfers took too many steps, transaction history buried the
answers people came for, and unclear states made users
double-check everything outside the app. A UX audit traced high
bounce and weak retention to
friction in the core transaction flow — the one journey
every user takes.

TeamProduct, Engineering, Marketing
Timeline~3 months, iterative sprints
Stage A — Low fidelity
Structure before style
I rebuilt the flow's skeleton first:
surface balance and recent activity on one screen, cut the
transfer journey from five steps to three, and give every
transaction a state users can read at a glance. Wireframes were
tested with quick hallway reviews before any visual design began.
balance first
scannable states
WF-01 · Home / activity

one primary action
WF-02 · Transfer — 3 steps
unambiguous state
receipt inline
WF-03 · Confirmation
Decision: transfer reduced 5 → 3 steps
Decision: status legible without opening detail
Killed: promo carousel above activity feed
Stage B — High fidelity
Calm surfaces · zero ambiguity
The visual language is deliberately quiet —
a dark, low-glare surface with one accent, generous type for
amounts, and color reserved for meaning: green in, neutral out,
amber pending. Every state was prototyped and refined against
stakeholder and usability feedback across sprints.

Case Study 02
Rapido — Driver app redesign
2023 · Mobility · Mobile
The problem
Drivers work the app one-handed, on the move, in sunlight.
Rapido's driver experience buried the two things drivers care
about — the next ride and today's earnings — under
cluttered navigation. Onboarding friction slowed new-driver
activation, and mid-ride screens demanded too much attention at
exactly the wrong moment.
RoleProduct Designer — driver experience
ScopeUser flows, wireframes, full interface redesign
TeamProduct, Engineering, Ops
Timeline6 months, launch + iteration
Stage A — Low fidelity
Glanceable · thumb-first
The wireframes enforced one rule:
anything a driver needs mid-shift lives in the bottom half of the
screen, reachable by thumb. Ride requests became a single decisive card
with the three facts that matter — fare, distance, pickup — and
earnings got a permanent home instead of a buried menu item.
map = context only
go online: thumb zone
WF-01 · Driver home
3 facts only
accept ≠ decline size
WF-02 · Ride request
Decision: ride card readable in under 2 seconds
Decision: earnings promoted to primary nav
Killed: hamburger menu hiding core tasks
Stage B — High fidelity
High contrast · big targets
Hi-fi screens use
oversized type, high-contrast surfaces, and one warm accent
tuned for outdoor visibility. Within two months of launch, the
redesigned interface lifted driver engagement by 30% and cut
onboarding friction for new drivers.
