The platform needed logistics and payments built from the ground up, capable of absorbing flash-sale traffic spikes and rolling out across four countries at once.
Java and Spring Boot microservices with REST APIs, integrating third-party logistics and payment providers through API Gateway and Lambda. Kafka carried async event streaming at the core of every transaction flow, with circuit breaking for fault tolerance. Data pipelines fed analytics and recommendation models.
Two million requests a day. The platform absorbed ten times normal traffic during flash sales without degradation, and shipped zero-downtime across four countries simultaneously, with our co-founder leading the engineering effort.
Four microservices powering retrieval, generation, configuration and memory as a knowledge agent inside a larger agentic system.
