MAMESTACKBY IVAN Say hello
Ivan's personal workbench

I make things I wish existed.

I’m Ivan. I explore markets, AI, product design, and playful software—usually by turning a question into something I can test.

See what I’m exploring What is MameStack?
MAME + STACK

Not a company or an accelerator. It’s the name I give to the body of work: questions, experiments, systems, and the few ideas worth carrying forward.

The through-line

Small questions can open into whole systems.

I look closely, build enough to make the idea real, and keep only what earns its place. MameStack is the record of that practice—not a polished catalogue and not a promise that every experiment becomes a product.

Recurring threads

The subjects I keep returning to.

Markets & decisions

How interfaces can make risk, liquidity, and uncertainty easier to reason about before a decision is made.

SEE THE PRESSURE

AI that follows through

How agents can hold context, use tools, and carry work to a verifiable finish while keeping people in control.

FINISH THE LOOP

Learning through play

How interactive systems can make a difficult idea felt and practised, instead of merely explained.

MAKE IT FELT

Everyday infrastructure

How quiet software can reduce friction around planning, memory, and the small operations of daily life.

LESS TO CARRY

On the workbench now

A snapshot of questions,
not a product catalogue.

01MARKETS

Can a trading interface show the cost of a choice before the choice feels obvious?

I’m interested in tools that expose pressure and trade-offs without pretending uncertainty can be removed.

02AGENTS

What changes when an assistant remembers the work, not just the conversation?

I’m exploring continuity, delegation, and verification as product materials—not invisible plumbing.

03PLAY

Can practice feel more like a game without making the subject less serious?

I’m looking for the point where consequence, feedback, and curiosity turn knowledge into judgment.

WORKING NOTE / 2026

Most of what I make stays private while it is still finding its shape. I’ll share more when the work can speak for itself.

How I build

Make the question tangible. Let use decide.

  1. 01

    Start with the friction.

    I begin with a decision, behaviour, or repeated annoyance—not a technology looking for somewhere to land.

  2. 02

    Build enough to think with.

    A working sketch reveals more than a perfect plan. The first version exists to make the real questions visible.

  3. 03

    Keep the edges honest.

    Real states, real constraints, and clear uncertainty matter even when the work is still rough.

  4. 04

    Keep only what earns it.

    Use is the filter. Some ideas deepen, some combine with others, and some are allowed to end.

About

Hi, I’m Ivan.

I’m an independent builder with a habit of crossing categories. Markets lead into interface design. AI leads into operations and memory. Games lead back to learning, risk, and human behaviour.

MameStack is my personal label for that body of work. It’s intentionally broader than a portfolio and smaller than a company: one place for the ideas, experiments, and lessons that connect what I make.

Does something here overlap with your world?
