Moses Qiu

I’m a product-minded backend and full-stack software engineer with production experience since 2021, delivering end-to-end ownership across 30+ web products. I’ve built systems serving 10,000+ users and processing 1M+ records, and I’m comfortable turning ambiguous requirements into shipped software using Python, Go, TypeScript, and Kotlin.

As a Technical Manager (Remote), I owned engineering for a production Django narrative-game platform—from legacy-code refactoring and feature delivery through releases, monitoring, and incident response. I moved session state and live leaderboards to Redis, cutting main-page latency by 200–300 ms and reducing database load, while also standardizing Linux and Nginx deployments.

Through freelance work, I delivered 30+ production web applications spanning SaaS, analytics dashboards, internal tools, and customer-facing websites—leading discovery, system design, frontend and backend implementation, authorization and data modeling, Docker deployment, production debugging, and client handoff. My recent projects include an Education data & analytics platform that reached 10,000+ registered users across 8,000+ schools and processed 1M+ grade records, plus backend-focused builds like Plystra Core (versioned capabilities, generated SDKs, integration tests) and Scoplen (event-driven idempotent flows, offline-ready sync, and a traced RAG pipeline).
