An AI Skill plaza for agent learning: daily hot Skill browsing, batch Skill download and installation, and the Understanding AI Agents learning entry.

• Astro
• AI Skills
• Windows CLI

A production-shaped Hono/PostgreSQL/Redis/BullMQ SaaS engineering template with ten implemented interface locales for foreign-trade scenarios, API-key boundaries, OpenAPI, health probes, workers, and verification scripts.

• Hono
• PostgreSQL
• Redis
• BullMQ
• Docker

An invite-only Career Radar product that separates public discovery, tenant-scoped matching/explanation, delivery digests, AI assessment preparation, and inbox state into reviewable agent-labeled workflows.

• Account isolation
• Agent workflows
• Scheduled digests

An offline Gaokao physics question-bank desktop app for search, practice, paper assembly, rich question review, and export. Evidence supports a Tauri-style Alpha/Beta desktop workflow over SQLite-backed data; Windows/macOS packaging is kept as a target boundary rather than a published-release claim. Agent help stays bounded to supervised export/review workflows.

• Tauri
• SQLite
• Question review

A closed-source web controller for cell-location workflows: coordinate recording, image association, embedding, trimming, session organization, and export are shown through a limited public overview.

• Closed source
• Product engineering
• System design

The core 1D implementation in a VMD project family, using C++ and Eigen for signal-processing experiments.

• C++
• Eigen
• Signal processing
• VMD

A closed-source fashion design platform for product configuration, outfit composition, component choices, colors, pattern matrices, and layer-structure workflows.

The engineering record is limited to the latest resume-backed scope: REST API design, PostgreSQL/JSONB models for design sessions and product parameters, admin/backend modules, supply-chain data flows, and supervised AI-assisted delivery evidence.

• Path planning

A GPT-assisted tool for evaluating and improving IELTS writing drafts.

• JavaScript
• GPT
• English learning

A fork-based desktop pipeline that combines Bili23 Downloader with faster-whisper so completed Bilibili downloads can enter a local GPU transcription queue and produce subtitle/text outputs.

• Python
• Bilibili
• faster-whisper
• PySide6

A C++ implementation of CEEMDAN for empirical mode decomposition and signal-processing experiments, presented alongside the VMD project family.

• C++
• CEEMDAN
• Signal processing

A closed-source developer English learning site that presents the learning entry while course, account, and operational details stay outside the public portfolio surface.

The verified engineering scope comes from the latest resume-backed online education work behind it: React, NestJS, Drizzle ORM, PostgreSQL, REST APIs, course purchase, scheduling, payment/refund support, and teacher/student/admin role flows.
