Building useful AI,
grounded in data.

I'm Evan Sun. I build research tools and data workflows that turn fragmented business and financial information into useful, checkable outputs.

FROM QUESTION TO SOMETHING USEFUL

Start with the source.

Public filings, company evidence, or a clearly defined dataset.

01

Build a useful workflow.

Connect the data, structure the task, and make the output usable.

02

Keep the result checkable.

Show the sources, the assumptions, and what still needs review.

ABOUT ME

Analytical mind.
Practical builder.

I'm Evan, a builder with a background in economics and business analytics at UC Santa Cruz and UC Davis. I work where company research, financial questions, and application development meet.

I turn scattered information into something useful: a report with sources, a repeatable data workflow, or an application whose results can be checked. My projects use AI where it helps and explicit rules where the result needs to be predictable.

I develop with AI coding assistance, review the output, and make the implementation's evidence and limits visible.

Small scope. Useful deliverables.

  • Source register
  • Missing-information log

Discuss a project

AI with a clear job.

Prototype a focused research or internal workflow with structured output, source references, and a review step before the result is used.

  • Failure and limitation notes
Discuss a project

Start with a sample input and an agreed output. I'll help define the scope, the checks, and the handoff.
