Micro-services for a Billion people
summary
A startup builds an Android marketplace for 12.8 million retail FMCG owners, iterating from SMS to app to microservices and saving supply chains money and waste. Architecture uses DynamoDB + Kinesis + Elasticsearch, later swapping lambdas for services and introducing a virtual backend cart that batches same-day swipes to cut shipping. Results: revenue grows from $200 to $8,000/day, retail reach 10→400, and 27% food wastage reduction while cloud costs jump from $500 to $4,500/month.
