8 years engineering high-concurrency SaaS applications and cost-optimized AWS architectures that save budget and scale seamlessly.
Rescued a client's Next.js financial portal from a fragile, local SQLite database and manual FTP deployments. Migrated schema to AWS RDS PostgreSQL, deployed scalable ECS Fargate tasks behind an ALB, and designed a query cache system to support 100+ concurrent trade-show visitors under a strict $100/month AWS budget. Integrated automatic CI/CD so the client can safely merge code to production.
Solo-architected a multi-tenant marketing automation platform with 6 applications, 55 data models, multi-LLM AI engine, dual payment systems (Stripe + WeChat Pay), and social media integration with Chinese platforms.
Solo-engineered an original RPG guild management game (*This Guild is Paying Off Debt*) using Cocos Creator 3.8 and TypeScript. Designed a decoupled, 100% configuration-driven game loop (Core gameplay logic separated from visual assets). Configured WeChat CloudBase serverless synchronization for billing, sub-packaging rules for fast startup, and automated configuration validation. (Currently in active staging phase).
A production-ready SaaS template built with Next.js 15 App Router, Prisma ORM, Tailwind CSS, and a custom Multi-LLM Routing Engine. Includes user management, campaign dashboard with AI Copywriter generation, and Swagger API documentation.
A Spring Boot 3 matchmaking engine for influencer marketing campaigns. Uses a custom 4D weighted cosine-similarity algorithm to rank KOLs based on category, followers, engagement, and budget. Integrates Redis for high-speed caching and RabbitMQ for asynchronous event processing.
