I am XXX Clark, a computer science graduate student and product-minded engineer in Chongqing. I work where AI research meets software that people can actually use: agent workflows, vision models, backend systems, and the stubborn last mile between a convincing demo and a dependable product.

Research that can reason. LangGraph workflows, hybrid Web/RAG retrieval, relevance scoring, reflection loops, streaming reports, and source-grounded answers. Python · LangGraph · FastAPI · Milvus
|
Models that see the edge cases. Road-crack segmentation with Mamba, frequency enhancement, lightweight directional features, and deployment-aware experiments. PyTorch · Mamba · Segmentation
|
Ideas turned into working software. Java APIs, Vue admin panels, WeChat mini programs, desktop utilities, data workflows, and the details that connect them. Java · Spring Boot · Vue · Redis

An agentic research engine that knows when the evidence is not good enough. Python · LangGraph · RAG · FastAPI
|
Built a multi-agent research workflow that turns an open-ended question into a source-grounded report through planning, hybrid retrieval, evidence judging, analysis, reflection, and writing. Key decisions: carry evidence through a typed shared state; keep retrieval, judgment, analysis, and writing as separate responsibilities; bind claims to source IDs; route incomplete research back into targeted supplementary search. |

One control surface for a fragmented commerce lifecycle. Java · Spring Boot · Vue · MySQL
|
Designed the integration layer between third-party commerce APIs and internal operations. The system unifies product, order, logistics, after-sales, customer, and wallet workflows behind a modular service boundary. Key decisions: combine scheduled reconciliation with callback-driven updates; preserve status histories and callback logs for traceability; model wallet balances, freezes, and transactions as separate concerns. |
|
A reusable baseline for business systems that need control, not just CRUD. Spring Security · JWT · RBAC · Vue
|
Built a full-stack application foundation around authentication, authorization, observability, and environment isolation so new products can begin with operational essentials already in place. Key decisions: database-backed permissions; automatic synchronization of permission codes from |
|
Turning spreadsheet operations into a controlled public service. Spring Boot · Vue · JPA · MySQL
|
Reframed a manual result-query process as a focused web product: administrators import structured records and manage claim channels, while participants receive a simple public lookup experience. Key decisions: access and refresh token separation with rotation; login lockout and endpoint rate limits; batch imports; isolated development and production configuration. |
Research track: MAC-Net explores Mamba-assisted feature extraction and frequency enhancement for road-crack segmentation.
- Model the failure paths before polishing the happy path.
- Keep boundaries explicit: domain logic, integrations, persistence, and interface.
- Treat research claims as hypotheses until experiments and implementation agree.
- Prefer a small system that can be understood over a large one that can only be admired.
