+
+## About Me
+
+![bg  left](../img/interns/lindie-strijdom.webp)
+
+* Intern at **Kartoza**
+* Background in spatial analysis
+* Passionate about data-driven decision making and map design
+
+---
+
+## Analysis Problem
+
+* What’s the shortest route between two points?
+* Which roads need repair?
+
+---
+
+## Why These Problems?
+
+Poor road conditions near my home inspired me to analyze routes and identify problem areas.
+
+---
+
+## The Workflow
+
+<div align="center">

+
+## The Tools
+
+|        |     |
+|-------------------|---------------------|
+| QGIS              | PostgreSQL/PostGIS  |
+| QFieldCloud       | pgAdmin             |
+| QNEAT3            | VS Code             |
+| Git and GitHub    | Marp                |

+
+## Field Collection
+
+Data collected in the field using the QFieldCloud mobile app
+

+
+---
+
+![bg left](../img/roads-collection.png)
+
+## Collection Results
+
+* 108 points
+* 139 lines
+* 1,9 km² study area
+
+---
+
+## Methodology

+
+## Results - 1
+
+### Shortest distance analysis
+
+* ~1,2 km travel distance
+* ~2 min travel time
+
+![bg right](../img/roads-results-1.png)
+
+---
+
+## Results - 2
+
+### Road condition
+
+* 24% in need of repair
+
+![bg left](../img/roads-results-2.png)
+
+---
+
+## Insights
+
+* 30 segments need repair (~2,6 km total)
+* 3 segments critical (~639 m total)
+
+---
+
+## Recommendation
+
+* Fully reconstruct Burg Street
+* Partially repair Berg Street
+
+---
+
+## Further Research
+
+If I had more time, I would:
+
+* Use more advanced networking tools (pgRouting)
+* Digitize bridge and speed bump features
+* Increase the study area
+
+---
+
+## My Internship Experience
+
+### Highlights
+
+* ✅ Learned to use QGIS and multiple other software/tools
+* 🤝 Collaborated on a real project and gained experience
+* 🎯 Gained confidence in presenting and communication
+* 💬 Learned effective time management
+

+
+## Other Projects
+
+---
+
+### Bob Ross in QGIS
+
+Recreated a Bob Ross scene using only QGIS symbology and tools.
