Services

I build custom software that saves time, cuts errors, and keeps running after launch. Every project starts with the workflow that hurts, ships a working slice fast, and improves from real use.

Remote worldwide, bilingual (English / 中文). Reliable beats impressive.

Custom Web App DevelopmentTurn the spreadsheet-and-email workflow into software your team actually uses.
SaaS MVP for FoundersThe first version paying customers can use - scoped honestly, shipped on time.
Web Performance and Core Web VitalsMeasured speed fixes - not a cache plugin and a prayer.
API Integrations and Data SyncConnect the systems so nobody copies data by hand.
Workflow AutomationReplace the two-hour weekly task with something that runs in seconds.
Practical AI and LLM IntegrationAI that cuts real work - no chatbot theater.
Legacy Modernization and Platform MigrationMove off the "temporary" system without losing what people quietly depend on.
Cloud Setup and CI/CDDeploys that are boring: push, build, test, ship - with a way back.
Fractional Engineering and Technical AdvisorySenior engineering on call - without the full-time hire.
