02 / WORKING APPROACH

Understand the work.
Then build the system.

The same habits connect my finance work and personal projects: get close to the problem, make the process clear, and keep improving.

01

Start with the decision.

Understand what someone needs to know or do before choosing a tool.

02

Make the details hold up.

Clear ownership, useful controls, and traceable information make a system easier to trust.

03

Build, use, improve.

Put an idea into a usable form. Learn from the friction. Refine what matters.

03 / A LITTLE ABOUT ME

Always curious.
Usually building something.

My career is in finance. Building software with AI gives me another way to understand problems, explore ideas, and make something useful.

That curiosity extends to robotics, 3D printing, and endurance sports. I like things that reward both careful thinking and consistent practice.

CASE STUDY / 01

LottoTally

An accounting problem, translated into a practical tool.

The problem

Lottery reconciliation brings together daily activity, scratch-off inventory, and settlement information. Those pieces need to tell a coherent story.

The approach

The MVP organizes daily entry and history, book tracking, and commission reconciliation around a repeatable review process. Discrepancies become something to investigate within the workflow.

My role

Product direction, accounting workflow design, and AI-assisted development.

Personal project · MVP. The portfolio illustration explains the workflow.

CASE STUDY / 02

Vantage

Exploring automation with operational discipline.

The problem

Combining market inputs and automated actions creates questions about risk, duplicate actions, reconciliation, and oversight.

The approach

Vantage brings research inputs together with risk checks and a record of decisions. Reconciliation and monitoring are part of the design, alongside the automation itself.

My role

Product direction, workflow design, and AI-assisted development.

Personal research project. This case study describes system design, without making performance or live-trading claims.

CASE STUDY / 03

Spellcraft

A weekly learning routine with a sense of play.

The problem

A word list is a starting point. Practice also needs variety, a clear next step, and a way to see progress.

The approach

Spoken pre-tests lead into four adaptive practice games, with a parent view for following progress across the weekly spelling adventure.

My role

Product direction, learning workflow design, and AI-assisted development.

Private personal project. The illustration uses an example word.
