Building software for messy business operations.

Document-heavy workflows, operational tooling, and human-supervised AI systems. Built around real problems rather than predefined software categories.

01 / SELECTED WORK

Overline

Offline-First Mobile PDF Editor

A touch-first PDF editor for Android, built on the open-source PdfCraft Rust engine. Runs completely on-device without requiring accounts, subscriptions, or cloud processing.

Clover

Couple Life App

A cross-platform product for long-distance couples: shared schedules, timezone-aware free-window overlap, Cal.com calendar sync, and a full suite of couple-specific features across Flutter and a React PWA.

Translation Pipeline

Technical Document Translation

A pipeline for translating Chinese technical PDFs into reconstructed English documents while preserving tables, figures, formulas, and page structure.

XtracT

A hybrid OCR system that runs PaddleOCR and Tesseract in parallel, measures per-field confidence and cross-engine agreement, then decides whether to invoke a vision model, and in what mode.

02 / CURRENT FOCUSVisit Site

Integrated Processing Environment

Orinex

An operating system for businesses that run on messy documents and emails.

Built to solve real bottlenecks in a manufacturing business. Orinex replaces manual data entry and fragmented tools with an AI-native workspace. It treats emails, PDFs, and inventory lookups as independent objects that humans and AI agents can process in tandem, without rigid workflows.

Interactive Workspace

Next.js · Univer

Interfaces for reviewing items, working with spreadsheet-backed documents, editing data, and handling operational work.

Core Service

Spring Boot · PostgreSQL

Workspace-scoped backend handling templates, processing state, document data, inventory lookups, and persistence.

Document System

Univer · Rendering Pipeline

Structured spreadsheet documents hydrated from backend data and prepared for operational output.

Agent Layer

LLMs · Human Review

Agents prepare, extract, and transform work while people remain in control at judgment-heavy points.
