Ata Caner Cetinkaya: Rust systems engineer, compiler engineer, AI and machine learning engineer, and open-source contributor.
Rust / C++ / 9 projects / open source merged into burn
I work the whole arc of a product: sketch the interface, draw the system, write the Rust underneath, ship the thing. One person where you'd usually hire three.
Everything below is live. That's the point.
act i · the shape and the system
interface design
A page that keeps finding new shapes for itself. Drag a seam to resize two blocks, or hold a block and drag it over another to swap their places.
An interactive wireframe of a web page that rearranges between layouts on its own. Drag the divider between two blocks to resize them, or press and hold a block then drag it onto another to swap their places. The rest of the layout reflows to fit.
systems architecture
Hold to flood the system. Analytics gets sacrificed to keep the checkout lane up: it delivers every packet, at any load, on purpose.
An interactive diagram of a system under load. Checkout traffic rides a reserved fast-path straight through the core and is never dropped; analytics traffic flows through a bounded shared queue. Holding a pointer on the widget raises the arrival rate: the queue backs up and analytics packets are shed to protect capacity, while a live readout shows checkout staying at one hundred per cent delivered and analytics switching to shedding. Releasing lets the system drain back to steady state.
act ii · the discipline and the material

Everyone wants to ship faster. Skip a gate and see what your users get.

creative code
This site's field is not a stock effect. It is a material I built, and what you have been brushing past since the top of the page is running right here, dials exposed.
Sitting on an idea that deserves to exist? Commissions open.
Get in touchNothing above is a video. Hand-built simulations, live in this page: a slot-tree layout engine, a queue under real backpressure, a delivery line with consequences, and the site's own field.
9 projects, 4 domains, four screens. Hover anything; every card opens into its own landing page.
learning systems
Two projects working with intelligence, memory and retrieval.
continual intelligence
A brain-inspired continual-learning substrate, built without backpropagation.
Learning persists across laps; nothing is ever retrained from zero.
rustbevyblas
local semantic search
Semantic search across your own image library, running entirely on your machine.
Three models argue about every image; one answer leaves the room.
rusttaurireactpython
market machinery
Two projects reading and executing the structures beneath price.
defi analytics
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
A lock-free limit-order-book matching engine, written in safe Rust.
Price-time priority with no locks anywhere on the hot path.
rusttokioratatuihdrhistogram
sharp instruments
Two projects making the invisible costs of software visible.
where time goes
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
An interactive substrate for learning hard technical material by doing it.
Structure you traverse beats prose you skim.
reacttaurimdxkatex
software that acts
Three projects where the users are programs: status, pipelines, commerce.
agent pipeline
An agent-driven pipeline that runs a job search like an engineering project.
Hundreds discovered, dozens graded, a handful tailored; volume becomes precision.
rusttokiosqliteratatui
ambient agent status
Your Mac's notch becomes a live status surface for coding agents.
Your agents' heartbeat, glanceable without ever switching context.
swiftswiftui
agent commerce
A storefront built for AI agents to buy from, not browse.
Orders placed and fulfilled by software; the storefront speaks protocol.external →
