Projects

# Things I've built

Libraries I maintain and testing tooling I built because I needed it, plus the products I've shipped as an engineer on a team. Star and install counts are live from GitHub and npm.

## Open source

-   ### [state-in-url](https://asmyshlyaev177.dev/projects/state-in-url.md)
    
    Stores nested, typed state directly in the URL via React hooks. I built it because I needed a fast, convenient way to preserve state on page reload and share page links.
    
    -   React
    -   TypeScript
    -   Tailwind
    -   Next.js
    -   Remix.js
    -   react-router
    
    419 2.8k/wk
    
    !    
-   ### [react-horizontal-scrolling-menu](https://asmyshlyaev177.dev/projects/react-horizontal-scrolling-menu.md)
    
    A reusable horizontal scroll component. TypeScript, well tested, and used in production dashboards I never get to see. Maintained for years across multiple React majors and refactored along the way.
    
    -   React.js
    -   CI/CD
    -   storybook
    -   npm
    
    790 95k/wk
    
    !    
-   ### [test-proxy-recorder](https://asmyshlyaev177.dev/projects/test-proxy-recorder.md)
    
    VCR for Playwright - records real API responses once, then replays them deterministically on CI. Covers Next.js SSR, browser, and WebSocket traffic with no backend and no hand-written mocks. I built it because every flaky e2e run traces back to the network.
    
    -   TypeScript
    -   Playwright
    -   Next.js
    -   WebSocket
    -   e2e
    -   npm
    
    78 76/wk
    
    !    
-   ### [X-Pat](https://asmyshlyaev177.dev/projects/x-profile-location.md)
    
    X-Pat, a browser extension that puts an X account's country in the hover card and the feed, using X's own location API through your existing session. The feed fills in as you scroll without draining the endpoint's rate limit, and accounts can be collapsed, hidden or highlighted by country, organisation, age or bio keyword.
    
    -   TypeScript
    -   Browser extension
    -   MV3
    -   Playwright
    -   Cloudflare Workers
    -   SQLite
    
    !    
-   ### [heatmap-analytics](https://asmyshlyaev177.dev/projects/heatmap-analytics.md)
    
    Self-hosted click and hover heatmaps, scroll depth, rage-click detection and ghost-cursor session replay, rendered on the live page. No cookies, no third-party scripts, and a tracker that is 1.7KB gzipped.
    
    -   Cloudflare Workers
    -   D1
    -   SQL
    -   TypeScript
    -   Node.js
    -   Analytics
    
-   ### [llm-queue](https://asmyshlyaev177.dev/projects/llm-queue.md)
    
    A single-worker priority queue for local LLMs, exposed as an OpenAI-compatible HTTP service - so cron jobs, browser extensions and OpenAI clients all share one serialized queue against one model instead of fighting over the GPU.
    
    -   Node.js
    -   TypeScript
    -   Ollama
    -   HTTP API
    -   CLI
    -   npm
    
-   ### [omarchy-last-session](https://asmyshlyaev177.dev/projects/omarchy-last-session.md)
    
    Session restore for Omarchy (Arch Linux with Hyprland): saves the windows you have open and brings them back after a reboot, shutdown, logout or crash, each on the workspace and monitor it was on. Python standard library only, no compositor patches, no extra daemons.
    
    -   Python
    -   Linux
    -   Hyprland
    -   Omarchy
    -   Plugin

-   ### [Omise - payments merchant dashboard](https://asmyshlyaev177.dev/projects/omise-payments-dashboard.md)
