EXPERIENCE

Starbucks

Technology Intern

Seattle, WA | Jun 2024 - Aug 2024

Transformed Starbucks’ Mobile Order & Pay multi-cloud SaaS platform by architecting a Kotlin + Spring Boot role-based admin system to streamline business data management.
Revamped the legacy Thymeleaf + HTML interface into a dynamic single-page application by migrating to React + TypeScript.
Developed the Spring Boot (Kotlin) backend serving as a REST proxy and cache and constructed file-based mocks for local testing.
Developed a React + Spring Boot feature for in-admin creation and testing of mobile orders, eliminating the need for Postman calls via corporate VPN and cutting setup overhead by 80%.
Implemented comprehensive unit and integration tests in TypeScript and coordinated QR testing and deployments across Kubernetes environments.
Won the Sweet 16 Award for a hackathon project that integrated customer survey feedback into the Starbucks app using Expo and React Native.
Participated in SCRUM ceremonies, including daily stand-ups, sprint planning, reviews, retrospectives, and user story refinements.

Cell Signaling Technology

Software Development Engineer Intern

Danvers, MA | Jun 2023 – Aug 2023

Designed and built an event-driven, microservice-based web app, “web2pdf,” using Spring Boot and Apache Kafka to convert webpage URLs into PDFs for later storage in a database, handling scheduled task traffic of up to 1k QPS.
Loose-couple the microservice for scalability and fault tolerance by developing an Kafka publish-subscribe architecture to handle burst traffic requests as async jobs; used Gradle to package the application and Dockerfiles to define its multi-stage build on a Debian image.
Integrated a Kafka KTable pipeline with a persistent state store to enable robust key-value lookups in Spring Boot RESTful APIs; maintained the API documentation on Swagger.
Deployed microservices to Kubernetes by creating resource manifests and validating with Docker Compose for auto-scalability; optimized pod resource usage to 7% using s6-overlay and tripled throughput as confirmed by Apache JMeter load tests.
Participated in the full SDLC, including building the CI/CD pipeline with Git Actions, Terraform, Amazon ECR, and ArgoCD to automate build processes and setup integration test for verification before promoting to next stage.

DeZhao

Software development engineer

Remote | May 2022 – Dec 2022

Led the front-end team in designing and implementing core features for the forum website “tietieus.com” including the user authentication framework, posting, content filter, and search, using Next.js (React), MongoDB and Node.js, then deployed on Vercel.
Developed the single page application by using AJAX functionalities to construct data pipelines; employed React data-fetching (static-site & dynamic routing) to reduce site latency by 20%; proficient in utilizing React Hooks to manage component states.
Enhanced forum post data integrity by using Mongoose to define robust schemas with strict validations. For advanced analytics, built MongoDB aggregation pipelines and integrated Python-based ETL tools to load partitioned data into BigQuery.
Completed team lead duties including hosting standups, interviewing candidates, conducting code review, and mentoring new hires, and coordinating with backend and mobile app teams
