I'm Cap · I help people build their ideas

Everyone is carrying an idea.

Tell me your ideaSee what I've built

No time, no first step, no developer

Most of them never get built.

An engineer who builds it with you

Tell me yours. I'll help you build it.

Tell me your idea

Mine · one live, one research paper, five on their way

Some of them are already being built.

Tell me your ideaSee all the work

The work.

Everything I've built so far: 17 projects across 6 domains, one scene at a time. Have a look around.

AI / ML

learning systems

Working with intelligence, memory and retrieval.

continual intelligence

NeuroDrive

A brain-inspired continual-learning substrate, built without backpropagation.

Learning persists across laps; nothing is ever retrained from zero.

rustbevyblas

media memory engine

Mnemosyne

A local-first media-memory engine, and the family of asset browsers built on it.

One engine owns the memory; every product just teaches it a new medium.

rusttaurireactonnx

measured, not predicted

Blaze

Contract-guarded kernel fusion: candidate plans race on the real GPU, and the winner holds only while its conditions do.

Measured per training step, with a real backward pass and real data: 4.9% past stock Burn's best setting, on a partition no static score can express.

rustburncubeclmetal

Finance

market machinery

Reading and executing the structures beneath price.

defi analytics

Aurix

Local-first DeFi analytics, from Uniswap V3 mechanics to cross-DEX arbitrage.

Uniswap V3 tick maths to cross-DEX arbitrage, decoded entirely on your machine.

rusttauritypescript

matching engine

Nyquestro

A lock-free limit-order-book matching engine, written in safe Rust.

Price-time priority with no locks anywhere on the hot path.

rusttokioratatuihdrhistogram

Systems

sharp instruments

Making the invisible costs of software visible.

where time goes

Performance Profiler

A profiler that shows where programs actually spend their time, without drowning you in it.

The hot path has nowhere to hide from a sampling profiler.

c#tmodloader

learning substrate

Tessarix

An interactive substrate for learning hard technical material by doing it.

Structure you traverse beats prose you skim.

reacttaurimdxkatex

Agents

software that acts

Where the users are programs: status, pipelines, commerce.

agent pipeline

Cernio

An agent-driven pipeline that runs a job search like an engineering project.

Hundreds discovered, dozens graded, a handful tailored; volume becomes precision.

rusttokiosqliteratatui

agent commerce

AgentFulfyl

A storefront built for AI agents to buy from, not browse.

Orders placed and fulfilled by software; the storefront speaks protocol.external →

Game Mods

mods for other games

New brains and progression for games I play: RimWorld, Tarkov and Terraria.

skills as progression

Escape from Tarkov RPG System

Escape from Tarkov's skills become the whole progression system: level a skill and its perks unlock.

62 skills, 27 of them dormant in the base game, now carry 922 milestones that unlock as you level them.

c#bepinexspt

colony-wide planner

Let Us Handle This

A RimWorld mod that takes over your colonists' work, needs and combat, so the Work tab is gone for good.

One planner gives every job to the colonist who will finish it soonest, and replans the moment the colony changes.

c#harmonyrimworld 1.6

ai companion

Multi... Player?

A Terraria companion that plays beside you: a flying orb that fights, mines and lights the way.

You never give it an order. It picks its next job from what is around you, and it grows stronger as you do.

c#tmodloader

Products

full-stack apps

Shipping the finished thing: software you download, open and use.

search by meaning

Lynceus

A local-first Mac image browser that finds any picture by what it means, not what it is named.

built on Mnemosyne

Thousands of images, searched by what they mean, none of them leaving your Mac.

rusttaurireactonnx

adaptive typing trainer

TypeNotch

An adaptive touch-typing trainer that lives in your MacBook's notch and drills the keys you actually miss.

Monkeytype measures you; TypeNotch trains you.

swiftswiftui

ambient agent status

VibeNotch

Your Mac's notch becomes a live status surface for coding agents.

Your agents' heartbeat, glanceable without ever switching context.

swiftswiftui

time into invoices

Vespora

A fully on-device macOS time tracker that narrates your day and turns it into billable hours.

The Mac's own AI writes up the day; nothing it reads ever leaves the machine.

swiftswiftuisqlite

workspace as tech tree

Nonlinear

A Linear workspace read as a horizontal tech tree on an endless canvas.

Read-only by design, and it runs on local demo data today rather than a live workspace.

Skills

the proof network

Symbols on the left, outputs on the right. A line means the two ends shipped together; unresolved claims say so.

outputs

the linker · symbols in / evidence out

46 / 18

46 symbols resolving into 18 outputs. A line means the two ends shipped together; its colour runs between the fields it connects. Dim symbols are unresolved: no public artefact yet.

Paid reach · open offer

Get paid to post.

I don't run brand accounts and I don't buy ads. I'd rather pay the people who post about the things I build. Pick any product, post what you actually think of it, then show me the numbers.

Starting rates. They'll move as I learn what reach is worth.

  1. 01 / post

    Any platform, any format, your own voice. Say what you think, including the parts that aren't flattering. And when you start posting, tell me: send an email or use the contact form below.

  2. 02 / send proof

    Analytics screenshots and the links, to ata02caner@gmail.com. One email is enough.

  3. 03 / get paid

    Bank transfer or PayPal, whichever you'd rather. A person reads every submission, and that person is me.

Disclose it Paid posts have to say they're paid, wherever you post them. That's UK advertising rules, not my preference. No disclosure, no payout.

Checked by hand I read the analytics myself. Bought or farmed views get nothing, and the call is mine.

Not a contract It's an open offer. It can change or pause at any time, so ask me first if the number matters to you.
