2023 — UX/UI Designer
REDEP
Designing a map-based data platform for Angola's E&P sector
REDEP is an E&P data repository built for ANPG, Angola's national petroleum agency. I designed a map-first interface that turns complex technical data — concessions, wells, rigs and related documentation — into a visual, accessible experience.
The challenge
E&P data is deeply technical and geographically anchored. The challenge was to move users beyond tables and lists into an interface that let experts locate, understand and access information faster.
The approach
Bringing the database closer to the real field
Instead of designing the experience only around abstract data structures, I focused on a more familiar mental model: geography.
Users could explore the repository through an interactive map where concessions, wells and rigs were represented as visible assets.
Each map element worked as an entry point into the database. By selecting an asset, users could access its information, metadata and related documentation.
This made the experience feel closer to how users already understand E&P data: through location, assets and relationships between them.
Wireframes
Before moving to high-fidelity UI, I explored the core screens and user flows through wireframes to validate structure, hierarchy and interaction patterns.

Key UX decisions
Map-first exploration
The map became a central part of the experience, allowing users to search visually and understand where each asset was located.
Asset previews
When selecting a concession, well or rig, users could see a quick preview before opening the full detail page. This helped them check relevance faster.
Structured detail pages
Detail pages were organised around clear hierarchy: primary information first, then metadata, related records and documentation.
Search and filtering
For users who already knew what they were looking for, the platform also supported direct search and filtering by relevant criteria.
Core user flow
REDEP supports distinct journeys for data consumers and administrators — from free and purchased asset access to full platform management.
Map exploration
Browse an interactive map to discover concessions, wells and rigs across Angola's E&P landscape.
Asset access
Preview asset details, access free documentation or unlock purchased records, then dive into full technical profiles.
Administration
Manage users, assign roles, curate the product catalog and control which assets are available to different user groups.
My role
As UX/UI Designer, I worked on:
- —User flows
- —Information architecture
- —Wireframes
- —High-fidelity UI
- —Map interaction patterns
- —Search and filtering experience
- —Asset detail pages
- —Reusable interface components
- —Developer handoff
Outcome
The final design transformed a technical repository into a visual, structured platform. Map-based exploration, search, filtering and detailed asset pages connected technical data to its geographic context, making concessions, wells and rigs easier to find and understand.
