- Developed automated Linux Bash scripts for application setup and configuration, cutting manual deployment time by 60% and standardizing environment initialization for consistent performance across client systems.
- Delivered rapid post-installation updates based on client feedback, enabling same-day patch delivery and improving system stability by 35%, leading to higher user satisfaction.
SDE Internship at Xi’an Suoer Software Technology Co., LTD, Xi’an, China
- Developed a real-time public transportation management system using Spring Boot + Vue.js, enabling live route tracking and status visualization for a local bus company.
- Implemented WebSocket-based real-time data streaming with incremental patch updates, reducing redundant polling and cutting P95 front-end latency from 1.2s to 350ms.
- Optimized UI performance with virtualized list rendering and frame-synced map animations, lowering first-screen load time from 2.8s to 1.6s and sustaining 60 FPS during interactions.
Projects
AWS-Based Reimbursement Automation System
- Developed an automated reimbursement approval platform on AWS, integrating Flask + MySQL (RDS) + Docker + Terraform to enable end-to-end submission, approval, and notification workflows.
- Automated infrastructure provisioning with Terraform and Packer, cutting deployment time from about 1 hour to less than 10 minutes and ensuring environment consistency via custom AMIs and remote state management (S3 + DynamoDB).
- Implemented serverless email verification and alerting using AWS Lambda + API Gateway + SendGrid API, achieving 45% lower cold-start latency through scheduled prewarming and CloudWatch monitoring.
- Integrated ChatGPT API to automate receipt validation and anomaly detection, streamlining the review workflow and improving overall processing efficiency by 35%.
Online Meal Ordering Platform
- Developed a cross-platform online meal ordering system, featuring a customer-facing web client built with React (Vite + Redis) and an admin mobile app using React Native (TypeScript) + React Query, delivering unified and performant user experience.
- Implemented event-driven architecture with RabbitMQ and WebSocket for real-time synchronization and designed an idempotent ordering and dual-ledger inventory model combining PostgreSQL + Redis, achieving 0% duplicate orders and near-zero overselling.
- Integrated secure, tokenized payments with Stripe SDKs and isolated Webhook services as microservices to strengthen security and system resilience.
- Validated the new platform through A/B testing, where 80% of users preferred it for its faster checkout flow and smoother mobile experience.
