About me

- I am a PhD-trained GeoAI researcher (Lincoln University, NZ) focused on GIS, Remote Sensing, and climate-risk applications. My work connects Earth observation data with practical interventions in urban resilience and environmental management.

- I work across QGIS, ArcGIS, Google Earth Engine, Python, and geospatial analytics pipelines to build end-to-end workflows: from data ingestion and modelling to decision-ready outputs.

- I am currently seeking roles as a GIS Researcher / Remote Sensing Scientist / Geospatial Data Scientist, with a focus on delivering measurable, decision-ready outcomes.

Selected GeoAI / Remote Sensing Projects

I design operational geospatial systems that translate Earth observation data into decisions cities and organisations can execute. I am currently open to roles in GIS Research, Remote Sensing Science, and Climate Risk Analytics.

Projects

Extreme Heat Resilience Decision System (On going)
Built a neighbourhood-level heat-risk workflow combining satellite EO, weather inputs, and local vulnerability layers for 24-72h action planning. Target outcomes: 2-5°C hotspot cooling, >=20% reduction in heat-exposure hours, and 10-25% cooling-energy reduction in intervention sites.
High-Accuracy Rice Identification Tool (ESA-funded case study, Dong Thap)
Developed geospatial classification workflows for rice mapping in the Mekong Delta using multi-source remote sensing data to support agricultural monitoring and planning.
UAV + Satellite Crop Monitoring Workflows (Lincoln Agritech)
Developed Python-based pipelines for imagery download, preprocessing, feature extraction, and reporting from Sentinel and UAV datasets to improve reproducible agronomic analysis.
Bucket Test from Space (PI)
Developed an AI tool using satellite imagery to detect irrigation issues and improve farm water efficiency.
Geospatial Capacity Building and Applied Research Delivery
Led workshops, technical documentation, and collaborative implementation across researchers, field teams, and stakeholders to convert GeoAI outputs into operational decisions.

Geospatial analysis is a rapidly growing field that combines geography, spatial data and technology to provide insights into a wide range of applications. Whether you're analyzing urban planning, disaster response, or the spread of disease, geospatial analysis provides a unique perspective on complex problems. In this blog, we will explore the latest trends, techniques and tools in geospatial analysis, and how it is changing the way we understand the world around us.

1. Spatial Programming & Remote Sensing - Spatial programming and remote sensing are essential components of modern technology and are transforming the way we understand our world.
2. Apply masks on Satellite Images - When we use Satellite Imagery, they usually provide masks for clouds, water, etc. I will show you how to apply masks to remove water pixels from satellite images.
3. Remove photo background by Python - Removing the background of an image using Python can be done using image processing and computer vision techniques. One popular method is using the OpenCV library, which provides a range of tools and functions for image processing and computer vision.
4. Watermark Photos with Python - To watermark photos using Python, you can use the Python Imaging Library (PIL) or OpenCV library. Both libraries provide tools for image processing and can be used to add a watermark to an image.
5. ChatGPT API with Python - To use the OpenAI API with Python, you will need to use the OpenAI API client library, which provides a Python interface for the API. The API client library makes it easy to interact with the API, allowing you to send requests to the API and receive responses in a convenient and easy-to-use format.
