I built Build4Me to address a trust problem in diaspora-funded construction projects.
Many families send money home to build houses but have no reliable way to verify that work is actually being done. Photos can be reused, progress exaggerated, or projects abandoned after funds are sent.
Build4Me introduces milestone-based funding where each construction milestone must be verified before funds are released.
The system verifies progress using: - geotagged photo capture - GPS location verification - AI image analysis - duplicate image detection
It runs on serverless AWS architecture using services like Rekognition, Bedrock, Lambda, DynamoDB, and Amazon Location Service.
Would love feedback on the architecture and fraud detection approach.
