What mattered in the build
Tso 2.0 ran live restaurant operations while the business grew from two locations to five. Tso 3.0 is the ground-up redesign built to address the architectural limits 2.0 had run into.
Developed and supported Tso 2.0 in production through the expansion to five locations, and migrated payment processing from Stripe to Cybersource.
Designed Tso 3.0's architecture from the ground up: microservices, and GraphQL in place of the REST APIs, which unblocked the other teams building on top.
Built the CI/CD pipeline, where a pull request label deploys any branch into an isolated Kubernetes preview namespace, with a Go service on Lambda cleaning up namespaces and ECR images once a branch is gone.
Led a cross-functional team of up to 7 while staying hands-on in the codebase.
A live commerce system where a bad architecture call would have hit real kitchens, drivers, and payments.
