Looks like you have JavaScript disabled. For the full Twine experience, you will need to re-enable it.

Ex-Google/Huawei · AI+Full-Stack Ship Fast I ship production software end-to-end: from API and data layer to UI, tests, and Docker handoff. Background. Former Google algorithm engineer and senior full-stack engineer on advertising / ad-serving related systems; previously Huawei full-stack and algorithm engineer. I design and harden pipelines under real traffic, then wrap them in clean APIs and ops that a small team can run without me. How I work. Problem → approach → deliverables. I clarify acceptance criteria early, cut scope into milestones, and leave you with runnable code plus a short integration guide—not a slide deck. What I deliver well - Full-stack web: JavaScript/TypeScript, React, Node.js, Python, FastAPI - AI/ML: PyTorch, TensorFlow, scikit-learn; LLM apps, RAG, and agent-style workflows - Automation & ops: scripts, browser automation, Gmail/Slack connectors, GitHub workflows, Shopify integrations - APIs, webhooks, data pipelines, Docker packaging, on-prem installs when data cannot leave your network - Interactive frontends: Three.js / WebGL demos and tooling UIs when the product needs them - Research → working PoC → documented handover (architecture, tests, README) Communication. Native Chinese (ZH) and working professional English (EN). Best for clients who want a single engineer who can own backend, ML glue, and a usable dashboard without a six-person squad. Open to fixed-price milestones on automation, AI integration, and compact SaaS/PoC builds. Prefer clear success metrics (latency, accuracy, "message in → reply out") over open-ended retainers.…Ex-Google/Huawei · AI+Full-Stack Ship Fast I ship production software end-to-end: from API and data layer to UI, tests, and Docker handoff.
