NGR

I owned the pre-launch reliability strategy for 6 national eCommerce brands: end-to-end, functional and load test plans, with JMeter load tests run in a dedicated performance environment. Over about 3 months, regression bugs fell by 33%.

I also built a multi-agent customer-service chatbot prototype (FastAPI, LangChain and Azure Postgres) to test customer-service automation, and defined how to measure it: order accuracy, cross-sell and time-to-serve.
