Full-stack developer from Poland, remote-first (CET). I build complete products in TypeScript and Rust: desktop apps with Tauri and Electron, end-to-end typesafe web apps with tRPC, Vite and TanStack, backends on Node and NestJS. I ship them properly: CI, tests, releases, docs, and upgrades users don't have to think about.

AutoMaker · ⭐ 3.2k
Autonomous AI dev studio: describe a feature on a Kanban board, a Claude agent implements it in an isolated git worktree, you review the diff. Started for fun with a team of 4 and grew into something much bigger within a month. I was the #1 contributor: agent execution pipeline, server architecture, auth, Docker/CI, and day-to-day issue triage.
Business ERP · in progress, private
The project I'm putting everything I know into. A grant-funded ERP I've been building for several months on a deliberately boring, proven stack: tRPC for end-to-end type safety, Vite, the TanStack family, Prisma and PostgreSQL. Multi-tenant data model, audited writes, typed contracts from database to UI. It's also where most of my lint rules come from.
noctcore/eslint-plugins · docs · npm
Guardrails for codebases where AI agents write a lot of the code. 13 packages with 110+ rules: ESLint plugins plus whole-repo rules for @noctcore/harness, catching what generic linters can't see: Prisma tenancy and transaction fences, SSRF and path traversal, fetch timeouts, structured logging, untrusted LLM output. Rules are promoted into a package only after they've caught something real, and every example in the docs runs in the test suite.

Shiranami · shiranami.app
Local-first music player for the files you already own. v2 is a ground-up rewrite from Electron to Rust + Tauri, shipped without stranding a single user's library: Windows installer 110 MB → 12.5 MB, idle RAM ~688 MB → ~291 MB, 189 ms cold boot, 1,500+ Rust tests. How the rewrite went →
Omniscribe
Runs up to 12 parallel AI coding sessions in one window, each with its own PTY terminal, git worktree, and MCP config. My daily driver.
ShiroAni · shiroani.app
Anime browser and tracker with a native C++ overlay.
shirone.dev · source
My portfolio as a desktop OS in the browser: draggable windows, ⌘K command palette, focus traps, reduced-motion support, noscript fallback. Next.js 16 + Tailwind v4.
