UX/UI design for
complex products,
not decorative screens.
Devlopa designs interfaces through research, systems thinking, prototyping, and evidence-based iteration. Every design decision is connected to user behavior, technical constraints, business goals, and product risk.
Start a UX EngagementOur UX process
Nine stages. Evidence at every step.
Discover
Stakeholder interviews, context mapping, and defining what success looks like for the product and its users.
Research
User interviews, task analysis, workflow observation, competitive review, and cognitive load assessment.
Map
FigJam journey maps, service blueprints, system maps, and information priority mapping, making the invisible visible.
Ideate
Sketch multiple layout models, compare tradeoffs, and converge on a design direction with stakeholder input.
Structure
Information architecture, content hierarchy, navigation design, and component inventory.
Prototype
High-fidelity Figma prototypes with interactive states, design system tokens, and responsive variants.
Test
Scenario-based usability tests, error rate measurement, confidence calibration, and synthesis of findings.
Handoff
Developer-ready Figma files, design tokens, component documentation, and handoff notes.
Iterate
Post-launch feedback loops, A/B testing collaboration, and continuous design improvement.
Tools & methods
Representative case studies
Five fully developed UX engagements.
These are representative case studies based on real UX engagement patterns. Each shows full research-to-handoff detail.
Geospatial Intelligence Command Platform
High-stakes interface design for geospatial event monitoring.
The Problem
Operators needed to monitor geospatial events, satellite-derived indicators, sensor feeds, field reports, and risk zones in one interface. Existing workflows required switching between GIS tools, spreadsheets, message threads, and static reports, creating cognitive overload and delayed decisions.
User Research Findings
- Cognitive load assessment revealed layer overload reduced decision speed by 40%
- Task analysis showed analysts switched tools 12+ times per investigation
- Time-critical decision points required sub-30-second triage capability
- Color-coding misuse created false urgency in 3 of 5 test scenarios
Users
Key Design Decisions
- Progressive disclosure to prevent map overload at initial load
- Separated observation, analysis, and recommendation layers to reduce confirmation bias
- Confidence indicators on all model-derived insights with source timestamps
- Spatial clustering at low zoom to prevent visual noise
- Temporal scrubber for change detection across time ranges
- Audit trail for all analyst decisions and escalations
- Accessibility for color-blind users and low-light command environments
Delivery Phases
Figma Prototype Screens
Fintech Risk Monitoring Dashboard
Precision risk interface with audit-grade decision traceability.
The Problem
Risk analysts needed to identify suspicious activity, monitor financial exposure, and escalate cases quickly, across multiple data sources with strict audit requirements.
User Research Findings
- Analysts scanned 200+ alerts per shift, prioritization was the core problem
- Alert fatigue led to escalation delays averaging 47 minutes
- Compliance required every decision to have a documented rationale
Users
Key Design Decisions
- Alert triage interface with severity hierarchy and smart grouping
- Entity profile drawers with cross-referenced transaction history
- Audit trail visible at every decision point
- Escalation workflow with mandatory documentation fields
- Color system based on severity, not category, reducing misclassification
Delivery Phases
Healthcare Patient Intake System
Accessible, form-forward intake design for diverse patient populations.
The Problem
Patient onboarding was slow, repetitive, and confusing, especially for elderly users, non-native speakers, and patients with low digital literacy.
User Research Findings
- Form abandonment occurred most often on step 3 of 6, medical history
- 29% of patients needed admin help to complete digital intake
- Plain language reduced re-read rates by estimated 40% in prototype testing
Users
Key Design Decisions
- Multi-step intake with progress indicators and save-and-return
- Plain language throughout, no medical jargon in patient-facing screens
- Accessible first, WCAG 2.1 AA, keyboard-navigable, screen reader tested
- Mobile-first layout, 64% of patients accessed via smartphone
- Clear error recovery with specific, actionable messages
Delivery Phases
E-commerce Personalization Experience
Reducing discovery friction and improving conversion through design.
The Problem
Customers struggled to find relevant products and abandoned shopping journeys, even when the product they needed was in stock.
User Research Findings
- Search-to-purchase conversion was 40% below industry average
- Customers compared 5+ products before purchasing, no comparison tool existed
- Wishlist abandonment correlated with checkout complexity, not price
Users
Key Design Decisions
- Personalized homepage with progressive personalization, no account required
- Product comparison drawer with side-by-side specifications
- Streamlined checkout with one-click return for saved addresses
- Performance-aware design, images lazy-loaded, animations disabled on slow connections
Delivery Phases
Logistics Fleet Operations Interface
Operational clarity for dispatchers managing time-critical fleet events.
The Problem
Operations teams needed better visibility into vehicles, drivers, shipments, exceptions, and delays, but existing tools were slow, cluttered, and required too many clicks for time-critical decisions.
User Research Findings
- Dispatchers made 30+ decisions per hour, UI latency created cascading delays
- Exception alerts were buried in general notifications, critical events missed
- Map vs table debate: dispatchers preferred map, managers preferred list, solution: both
Users
Key Design Decisions
- Split-view interface: fleet map + sortable shipment list
- Exception queue as first-class UI element, always visible
- Driver detail panel with ETA timeline and contact action
- Role-based views: dispatcher mode vs manager mode
- Reduced cognitive load through alert hierarchy and visual scanning patterns
