Learning the basics

Four years of algorithms, databases and networks. The groundwork for everything that follows.

First job, whole stack

The province's tourism websites were mine to build and keep alive. I wrote the pages, the C# behind them and the database under them, then trained the staff who ran them.

• tourzj.gov.cnZhejiang's provincial tourism portal
• wzta.gov.cnA city tourism site on the same platform
• Tourzj OAThe office system the bureau ran on

ASP.NET · C# · MSSQL · MySQL · jQuery · ExtJS

One system, end to end

Helios NetView NMS let operators check and configure mobile-signal repeaters from far away, over GPRS or SMS. I built all of it: the interface, the backend, the schema and the statistics. Then I taught customers to use it and kept it running.

• Helios NetView NMSRemote status and settings for signal repeaters

ExtJS · jQuery · Bootstrap · ASP.NET · C# · MSSQL · TCP/IP

The front end becomes the craft

From Sanming I moved fully to the front end. WioWise was a blogging and social publishing platform. I built its dashboard, cart and orders, and two tools that let people with no coding background make their own pages.

• WiseEditorRich-text editing for writers
• WiseBuilderA page and site builder that needs no code

React · Vue · webpack · Gulp · SASS · Rangy

Reading the signals

Trendalytics reads billions of online signals (searches, social posts, shared images) to tell fashion retailers which trends will sell before they produce anything. I built the dashboards that turn that data into answers for merchandisers.

Vue · Element UI · Node.js · Python · Elasticsearch · MongoDB

A thread that stays

Alongside everything else, one client has stayed with me: an AI platform for K-12 classroom teachers. Over the years I redesigned its classroom, moved its UI to Tailwind, rebuilt AI streaming on SSE, and designed the memory architecture for its core AI agents.

• Classroom v2Redesign, and the move from MUI to Tailwind
• AI streamingWebSocket to SSE, so replies stop dropping on school networks
• Agent memoryHow the core AI service remembers

React · Tailwind · Node.js · SSE · Claude Agent SDK

Data for cities

Quanturban builds data tools that help property developers and city governments plan and run cities in finer detail. In the same year I started freelancing on Upwork, which is where the next chapter came from.

Leading the front end

Know Your Customer runs identity and anti-money-laundering checks for financial institutions around the world. I joined as a senior frontend developer in February 2022 and was leading the front end by July. I also moved to Ireland. Today the work is a React and TypeScript codebase of 113,000 lines in 930 files, a distributed team, and the standards we hold it to.

• Organisation graphOwnership structures drawn with D3 and Canvas
• Risk dashboardsECharts views of each customer's risk profile
• Case managementEntity and Individual review workflows
• State and syncRedux Toolkit and RTK Query: 32 slices, 40+ cache tags, live updates over SignalR

Software that builds software

The newest stretch of the line is my own work. The largest piece is Kidoka. A bug or request becomes a ticket, AI agents plan it, write it and review it, and a person approves the pull request. It went from design doc to a working multi-agent platform in 12 days. Now it builds itself.
