Dan Liu

I’m a Full Stack Software Developer with 6+ years of experience building scalable SaaS, marketplace, and real-time data-driven platforms. I focus on end-to-end delivery—from UI/UX design to robust microservices and RESTful APIs—so products perform reliably under pressure.

I’ve proven results optimizing backend and frontend architectures for high concurrency, reliability, and large-scale data processing. At Glacier FarmMedia (March 2022 – Present), I led full-stack system design using Laravel, React, Vue.js, and integration work to support 1M+ marketplace listings.

I also build for performance and resilience: I implemented Redis-based queue systems, caching layers, and asynchronous workflows for authentication, real-time notifications, and saved search alerts. I optimized SQL queries and Elasticsearch/AWS Cloudsearch, and I diagnosed production issues across APIs, database schemas, frontend state, mobile app, and background queue jobs—drastically reducing system downtime.

I bring an engineering culture that’s practical and collaborative. I’ve mentored junior developers on technical design, clean code standards, and best practices, and I’ve leveraged AI-assisted workflows (Claude Code, ChatGPT, LLM-Assisted Workflows) to fast-track debugging and system refactoring.
