About Me — Narrative Poetry Meets Science

Memoire Est. 1926
Global Trade & Front-End Dev
"The intersection of art & commerce"

I am a researcher in digital trade, and an explorer of AI-Native engineering and front-end aesthetics.

My academic background comes from management science and international economics, focusing on the business dynamics behind cross-border e-commerce, platform data, geopolitical policy, and global retail networks; my practical path dives deep into information technology, using data modeling to understand trade flows, front-end interfaces to express complex logic, and automation alongside Agent workflows to solve efficiency problems in real businesses.

International trade and IT are not two isolated fields. Modern cross-border trade is itself a complex network jointly supported by platform rules, data APIs, algorithmic recommendations, payment links, logistics systems, and server architectures. To truly understand digital trade, one cannot rely solely on reading reports and papers; it also requires the engineering capabilities to model problems, automate processes, and build ideas into systems.

Therefore, I continuously integrate management science, trade research, full-stack engineering, and LLM toolchains: I research cross-border B2C direct mail, platform transaction data, and trade boundary reconstruction; I also engage in operations practices on platforms like Amazon and Mercado Libre to understand product selection, listing, claim SOPs, and process control. Simultaneously, I build personal websites, open-source tools, AI workspaces, and Linux collaborative environments to form a closed loop of research, product, and technology.

I believe valuable findings should not stay only in PDF papers, but should be seen, interacted with, and reused through high-quality information technology. Good tools do not exist just to show off skills, but are defined by real-world problems.

I hope to decompose abstract business problems into systems that are analyzable, deployable, demonstrable, and continuously iterative: let models serve decisions, let interfaces carry logic, let automation enter repetitive high-cost workflows, and let technology truly respond to reality.

General Tool Platform (AiNative-Tools)

Core Project Iterative Dev AI-Native Studio LangChain-style Workflow DEMO

Project Background

Built for cross-border e-commerce content production, automated product modification, image processing, and batch delivery, AiNative-Tools integrates product collection, Prompt orchestration, AI copywriting, white-background images, scene visuals, package delivery, and runtime observability into a local Studio workspace. The system uses directory contracts, task queues, plugin manifests, and status streams to organize sourcing, listing, asset generation, and delivery into configurable, resumable, and traceable production workflows. Its engineering shape follows a LangChain Workflow around e-commerce operations: each product batch moves through stable input, Prompt orchestration, model calls, structured parsing, image tools, and delivery tools.

My Responsibilities

Owned the productization of cross-border e-commerce content workflows, turning collection, product rewriting, translation, image generation, and delivery into an end-to-end local Studio process. I led the scope definition from business workflow decomposition to tool-boundary design and was responsible for making repetitive operations configurable, traceable, recoverable, and scalable for later expansion.

Technical Stack

A FastAPI + TaskManager + Manifest 3-layer control plane, where tasks progress from ingestion to delivery in batches, with real-time WebSocket state sync.

  • The frontend Studio Shell manages task queues, batch operations, and tool entrypoints in vanilla JS; the backend handles native/cloud/AI task channels via FastAPI async routes.
  • The Manifest layer auto-scans local SUM tool scripts and registers image processing, packing, and enhancement capabilities as configurable tool forms.
  • Core production chain: product URL/Excel input → Scraper → PromptComposer → AIClient → JSON Parser → Painter/PackTool delivery.
  • AIClient normalizes Gemini / OpenAI-Compatible model protocol differences; Structured Output Parser constrains model output into JSON consumable by downstream image tools.
  • Prompt Registry supports market-language substitution, stage slicing, and Sandwich-format packaging so different product batches run stably through the same pipeline.
  • Key Pool, state snapshots, and batch directories together provide recovery boundaries for retries, missing images, re-translation, and re-packaging.

Key Milestones

The project upgrades scattered operation tools into a visual, queued, and recoverable Studio control plane. It supports a full loop from product URL / Excel input to image-text collection, AI analysis, white-background preprocessing, batch scene-image generation, and delivery package assembly, while improving long-batch stability through directory contracts, state snapshots, Key Pool scheduling, and log replay. Batch folders act as stable input Schema, the self-built TaskStateStore works as Checkpoint, SharedGroupManager provides Memory-like State, and image / packaging scripts join the workflow as Tool Layer components, preserving clear recovery paths for failed runs, reruns, image supplementation, translation supplementation, and repackaging.
