Selected work
Practice and coursework projects: what each one is, what I did, what it does not do yet, and where to see it. The graduate research has its own page.
TechStarterWeb Consulting builds personal and small-business websites for clients in Taiwan, Hong Kong and Singapore. I co-founded it in October 2026 and lead the technical side. The studio's own site, live since 23 October 2026, is its first piece of work.
The need
The public pages take enquiries in three languages; a back office behind sign-in turns each one into an order with a status and a log of every change.
In use
Only the team's addresses can sign in to the back office, through Cloudflare Access with one-time email codes. The site is live on its own domain, with Google Search Console and visit statistics.
Limits
Enquiries are not yet emailed to the team, and Cloudflare's free plan has no servers in mainland China, so some networks load the site slowly or not at all.
How it was built
I set the requirements and review each change; the agent writes the code. Routine work goes to cheaper models: ten calls to the low-cost model came to about US$0.03.
Use the lowest layer that can do the job
How it stays on track
Each task card lists its goal and the files it may change, and CI fails a pull request that breaks the rules.
An individual Tableau story, submitted in December 2025: five dashboards on how mobile money is spreading across the Global South, built from World Bank Global Findex and GSMA data.
The data
An extract of 437 coded Findex fields across 174 economies was mapped down to 24 business-readable measures. The 2011 and 2022 waves were dropped for thin coverage, leaving 171 economies.
The story
A cover opens the story, five interactive dashboards follow, and a conclusion closes it.
What it found
Adoption expanded steadily from 2014. Digital payment use runs ahead of debit-card ownership, and savings trail both.
Limits
My critical assessment of each dashboard names the limits: no transaction-level detail and no qualitative evidence.
Where it led
Digital payment use running ahead of debit-card ownership raised the question my final-year project tested: what happens to banks' fee income as payments move away from cards.

The layered way of working that TechStarterWeb uses with AI coding agents. The five-layer figure is in the TechStarterWeb project above.
The idea
A lead agent turns a to-do into a task card, worker agents write the code, and scripts and CI check whatever a rule can decide.
State
Work state is kept in issues and handoff notes, so a new session can pick up where the last one stopped.
Rules
CI fails a pull request that edits files outside its task card, reuses a version number or skips the spec update.
Reuse
Published with tests, so that others can reuse or adapt it.
A panel of 39 commercial banks in Indonesia, Malaysia and Thailand, 2014–2022. The log specification shows a negative, statistically significant pooled association that comes mainly from differences between countries: a conditional association, not a causal effect.
