Software that
makes the work
flow better.

I’m Shen Yi. I simplify spreadsheet tasks, automate reports, and build practical web apps around the way people actually work.

From repetitive admin to complex internal processes, I focus on clear interfaces, useful workflows, and the details that help people get things done.

Original demo · Spreadsheet automation01

A weekly report,
without the copy-paste.

Combine two CSV exports, exclude matching duplicates, flag missing amounts, and create a category summary ready to open in Excel.

Try the sample to see the checks and download the result. It shows the kind of small, repeatable task I can help simplify for your business.

Internal software · Professional experience02

From image review
to a traceable workflow.

Internal tooling that brings image review, dataset preparation, training progress, and model exports into one interface.

My focus: clear review decisions, visible background progress, and version history that makes the process easier to follow.

Helping operators
stay in the workflow.

Prototype work on capture-and-review workflows and saved records, alongside experiments with voice and gesture controls.

Prototype work. Physical camera, recognition, and workshop performance need site validation. Illustration is not the company interface.

02 / Work with me

Start with one task.
Make it work better.

I take on small, clearly scoped software projects. We agree what’s useful, what’s included, and a realistic schedule before work starts.

01 —

Spreadsheet & report automation

Turn repetitive file processing, spreadsheet tasks, and recurring reports into a simpler sequence.

02 —

Internal web apps

Give a small team a clear place to review information, track requests, or manage a particular process.

03 —

Dashboards & integrations

Bring information from existing tools together, with useful summaries and a path into the details.

03 / A little about me

An engineering mindset.
A software toolkit.

My background spans hands-on engineering, field service, and software automation. Working close to physical operations has shaped how I approach software: understand the task, make the next step clear, and consider what happens when things don’t go to plan.

I’m currently an Assistant Engineer at Aetec, a systems integrator, contributing to software tools and automation workflows. Alongside work, I’m pursuing a part-time Bachelor of Technology in Computing at NTU.

I enjoy turning a complicated process into something people can understand and use.
