| Direction | What it means in practice |
|---|---|
| Quantitative research | Backtesting frameworks, out-of-sample validation, factor analysis, data pipelines, and financial research tooling. |
| AI × automation | Agent-friendly workflows that turn repetitive professional work—resume preparation, job applications, research digestion—into controlled, reviewable systems. |
| Local-first products | Useful tools with transparent data ownership: local storage where it matters, deliberate external calls where they add real value. |
| Project | What it does | Stack |
|---|---|---|
| jev-A-share-trader | A jev-powered technical analysis workspace for China A-shares, combining eight analytical dimensions into an evidence-backed assessment. Supports interactive charts, watchlists, and batch scans. | Python FastAPI React TA-Lib |
| JSON-Resume | Turns structured JSON into polished, one-page DOCX/PDF resumes. Includes an agent skill, validation, rendering contracts, and visual QA. | Python python-docx OOXML |
| Offer-Rain | A human-approved, agent-assisted email application workflow that pairs naturally with JSON-Resume. | Python SMTP Agent workflow |
| AlphaPai · Lanbaoshu Briefing Generator | Collects financial news, produces structured Word briefings, and optionally syncs to Feishu or drives WPS distribution. | Python Selenium LLM DOCX |
| Vocabulary Notebook | A local-first vocabulary system with FastAPI, React, FSRS-4.5 scheduling, SSE, and optional AI enrichment. | FastAPI React Vite FSRS |
| IELTS Scribe | A distraction-free, local IELTS writing practice desk with timers, autosave, history, and dark/light themes. | React Vite Express |
| Walk-Forward Reverse Crypto | A VWAP mean-reversion research framework with reverse rolling optimisation and strict out-of-sample validation. | Python Polars NumPy |
- Evidence first. A result is not done merely because code runs; the data path, output, and failure modes should be inspectable.
- Automation with guardrails. External actions remain deliberate and reviewable—especially when an email, document, or financial conclusion is involved.
- Good interfaces respect attention. I prefer dense, calm software that removes busywork instead of creating a dashboard-shaped distraction.
- Robust research infrastructure for asset-pricing and systematic trading work.
- Agent-native professional workflows that preserve user control instead of hiding decisions behind a chat box.
- Better ways to turn long-lived personal knowledge into useful, private tools.
Most projects are built to be used, inspected, and improved—not just displayed.
