What I'm looking for

Seeking long-term remote full-stack, backend, or DevOps work involving Python APIs, React/TypeScript, AI knowledge systems, and cloud delivery. I value clear requirements, code reviews, async updates, and agreed overlap hours. I can contribute from design through implementation and CI/CD. I prefer Chinese or written English; spoken English is improving.

I am a full-stack engineer focused on Python backend development, AI knowledge systems, and DevOps. I currently work at Shanghai Deyi Information Technology Co., Ltd., contributing to an enterprise AI development workbench and knowledge services for United Automotive Electronic Systems (UAES). My work covers third-party document ingestion, connectors, directory services, authentication, rate limiting and retries, multi-source synchronization, and document search and preview.

Previously, at Shenzhen Fubao Taotaro Technology Co., Ltd., I contributed to backend architecture, development coordination, and Kubernetes-centered delivery workflows. My projects included Lumio, a fundraising platform for Hong Kong NGOs; BinaryOwl, a multi-cloud platform; and the HKTDC Filmart IP Platform. Earlier roles included Python development at Nanjing Jiangmen Information Technology Co., Ltd. and Jiangsu Juneng Machinery Co., Ltd.

My stack includes Python, Go, FastAPI, Flask, React, TypeScript, Vue, Node.js, WeChat Mini Programs, and Flutter; PostgreSQL, MySQL, MongoDB, Redis, Qdrant, and Elasticsearch; Docker, Kubernetes, Helm, GitHub Actions, GitLab CI/CD, ArgoCD, Alibaba Cloud, Azure, and AWS. I have experience with RAG, OCR, API design, authentication and authorization, asynchronous tasks, technical documentation, and continuous delivery.

Selected projects include StratArk (AI-assisted strategy analysis), Just Cook (AI cooking assistance), Personal Cards Manager, Cambria Tech Portal, Noodle POS, Zhiwei Sixue (education and practice management), Huoke Portal and cable layout tools, ServiceFlow CRM, CareHub (hospital companion-bed rental), Donggu medical tourism, multi-store retail systems, the enterprise AI workbench and knowledge base, Lumio, BinaryOwl, HKTDC Filmart, and Taotaro DevOps. I contribute across requirements, design, backend and frontend implementation, integration, testing, and delivery. I am interested in long-term collaboration in full-stack, backend, and DevOps roles.

I have not yet held a formal remote position. I prepare for remote collaboration with written requirements, clear acceptance criteria, task boards, asynchronous progress updates, code reviews, automated checks, and agreed overlap hours. I am comfortable reading English technical documentation and communicating in written English; spoken English is still improving.
