I build production-ready backends and automate the boring parts — APIs, scrapers, CI/CD, and AI/LLM integrations that ship and stay up. Shipping since 2018: 3 years at VNG Corporation (Vietnam's largest internet company, 50M+ users, 99.9% uptime) and 50+ freelance projects rated 5.0. ✓ 3 years at VNG Corp (Vietnam's #1 tech company) — game servers handling thousands CCU, payment integration across SEA markets ✓ Full-stack: Node.js, Python, TypeScript, Next.js, React ✓ DevOps: Docker, Linux/systemd, CI/CD, Nginx, Redis — air-gapped RHEL 9.6 deployments; merged fixes upstream to Floppy (784★) and opencode-mem (1.6k★) ✓ Latest Upwork contract (AI startup): engineering the memory layer + dev pipeline — 13 merged PRs in a single week against a measured team baseline, with regression tests and a mutation matrix on every risky change ✓ UTC+7 timezone — your code ships while you sleep, 3-4hr overlap with AU/EU business hours What I do best: • Backend architecture — Node.js/Python APIs, dual-DB systems, payment gateways (Stripe, Google/Apple IAP) • DevOps — Docker multi-shard migrations, systemd service management, SSH-based monitoring tools • AI integration — OpenAI gateway streaming, AI-powered CRM, OCR automation pipelines I work independently, communicate proactively in clear English, and treat your project like my own.
