Projects

Tensho (2026). A mahjong roguelike: the tiles are familiar, the run structure is not.
Ouija + AI (2026). A Ouija board with a language model behind the planchette. The interface is the joke and the medium is the point.
LLM-driven system design (2026). A collection of system designs produced by driving language models through the exercise, written up as documents rather than transcripts.
Jumping Julia Maze (2026). A small mobile game, built to be finished rather than to be big.
Replica Island Reborn (2025). Replica Island, the open-source Android platformer, rebuilt as a web application.
mdreader (2025). A Markdown reader and editor that runs in the browser as a progressive web app, with nothing to install and nothing to upload.
Early apps, ported to the web (2025). The Android applications from early in my career, ported to the web so that they still run.
20 forms, 40+ design systems (2025). Twenty common forms, each implemented across more than forty different design systems, side by side.
MCPlator (2025). A calculator wired to the Model Context Protocol: arithmetic as a tool call.
evgeny.fyi (2025). A biography that wears the interface of every year it describes. Forty years of design history compiled to one static site.
Crosswordly (2025). A five-letter word game about building crosswords rather than guessing one word.
Eclipse simulator (2024). An eclipse simulator: three bodies, one shadow, and the geometry that decides who sees it.
Dragon Ball (2024). A submission for Algorithm Arena's ninth weekly challenge.
Front-end practice (2021). A set of exercises testing my own front-end skills, which turned into the most starred thing I had written at the time.
Laser-cut designs (2018). SVG designs cut on a laser cutter. Vector drawing with a physical failure mode: get the kerf wrong and the joints do not hold.
Experiments with Rust (2018). Experiments with Rust, kept as experiments rather than promoted into anything that had to keep working.
Windows Phone apps (2018). My Windows Phone applications, for a platform that no longer exists.
Early Android apps (2018). The Android applications from early in my career, collected into one repository rather than lost.
TombStone 2.0 (2018). The second run at an older project, which is usually where the design finally arrives.
Sumobot (2018). A sumo robot, prototyped in Matlab and then rewritten for an Arduino once it had to survive contact with another robot.
Code Review: the Game (2017). A game about reviewing code, which is either a joke about the day job or a way to practise it.
Learning Scala (2015). A repository of efforts to learn Scala, kept public so that abandoning it would be embarrassing.
Blind Day (2015). A simple adventure game in XAML and C++, built for the SFU WEG and WICS hackathon.
CLRS worked examples (2015). Worked examples from Introduction to Algorithms, written in Java while reading it.
First program (1993). It printed my name. Then it printed my name a thousand times. The second version felt like power.
