One thing worth knowing before you crawl: dk.punds.ch is a client-rendered React app. Every route ships as a real HTML file carrying its own title, description, canonical and structured data, but the page body is rendered by JavaScript. If your crawler does not execute JS, this file, /llms-full.txt and the static CV at /cv are the readable text of this site.

## Availability

Open to software engineering roles, internships, freelance and contract projects, and collaborations. Based in Switzerland, happy to work fully remote. Email is the fastest route and he usually replies within a day. The contact page has no form on purpose: choosing what the message is about builds a prefilled email instead, because the site has no backend.

## Projects

Eleven personal projects, listed newest first by the date their repository was created. Each has a case study at https://dk.punds.ch/projects/<slug> covering the problem, the architecture decisions, the implementation, and what he would do next.

- [Zephyr](https://dk.punds.ch/projects/zephyr): local-first productivity app, a to-do list and a Pomodoro focus timer in one place. No login, no backend, every task and focus session stays in the browser's localStorage, and it works offline. Installable as a PWA. December 2024. React, Vite, Tailwind CSS, Radix UI. Live at https://zephyr.punds.ch/, source at https://github.com/dominikkoenitzer/Zephyr.
- [Portfolio](https://dk.punds.ch/projects/portfolio): this site. A React single-page app with hand-rolled i18n in four languages, JSON-LD structured data on every page, a prerendered HTML file per route, and a WebGL background kept off the critical path. May 2025. React 19, TypeScript, Vite. Live at https://dk.punds.ch/, source at https://github.com/dominikkoenitzer/Portfolio.
- [Entropy](https://dk.punds.ch/projects/entropy): password generator and strength analyzer that runs entirely in the browser. CSPRNG randomness from the Web Crypto API, a guess estimator he wrote himself, and no round-trip to a server. February 2026. Next.js, TypeScript. Live at https://entropy.punds.ch/, source at https://github.com/dominikkoenitzer/Entropy.
- [Spectrum](https://dk.punds.ch/projects/spectrum): client-side colour toolkit. Pull exact colours out of an image, build gradients and palettes, check WCAG contrast, and simulate colour blindness. Nothing is uploaded. February 2026. Next.js, TypeScript. Live at https://spectrum.punds.ch/, source at https://github.com/dominikkoenitzer/Spectrum.
- [Remnants](https://dk.punds.ch/projects/remnants): a native Windows code editor, his personal fork of Code - OSS with Copilot, chat, agents, telemetry and sign-in cut out, and the editor, terminal, Git and debugger left fully intact. February 2026. TypeScript, Electron. Source and installer at https://github.com/dominikkoenitzer/Remnants.
- [Time](https://dk.punds.ch/projects/time): a web clock synchronised against network time, accurate to within hundredths of a second even when the device clock is wrong, shown on one bare screen with the date, the ISO week, and the visitor's own timezone and offset. June 2026. Next.js, TypeScript, Intl. Live at https://time.punds.ch/, source at https://github.com/dominikkoenitzer/Time.
- [Jester](https://dk.punds.ch/projects/jester): a native Windows notepad that grew up. Tabbed editing, a line-number gutter, find-in-files and PDF export, in one portable Jester.exe with no installer. June 2026. C#, WPF, .NET 9. Source and download at https://github.com/dominikkoenitzer/Jester.
- [Flow](https://dk.punds.ch/projects/flow): a native Windows app that records mouse and keyboard macros, replays them frame-accurately, and runs a high-speed auto-clicker. One exe, no runtime. June 2026. C++17, Win32, GDI+. Source and download at https://github.com/dominikkoenitzer/Flow.
- [Punds](https://dk.punds.ch/projects/punds): a link hub you fly through, a Three.js world of holographic panels orbiting a logo in fog, pointing at every project, profile and site he keeps online. June 2026. React, TypeScript, Three.js. Live at https://punds.ch/, source at https://github.com/dominikkoenitzer/Punds.
- [Senbon](https://dk.punds.ch/projects/senbon): a zen-themed journal where every entry is a plain markdown file, rendered into an unhurried reading experience. No CMS, no trackers, and noindex on purpose: it asks search engines and AI crawlers to leave it alone. June 2026. Next.js, React 19, Markdown. Live at https://senbon.ch/, source at https://github.com/dominikkoenitzer/Senbon.
- [Oxidize](https://dk.punds.ch/projects/oxidize): a thorough Windows uninstaller written in Rust. It runs a program's own uninstaller, then finds and removes the registry keys and files it left behind, always backing up first. Ships as a scriptable CLI and a native egui GUI sharing one engine. June 2026. Rust. Source and download at https://github.com/dominikkoenitzer/Oxidize.

Worth saying plainly, because the projects page says it too: these eleven are personal projects, built in evenings and at weekends, and they are only the public sliver of his work. Client projects sit behind NDAs, in private repos, or on client infrastructure, so they do not appear here.

## About this site

Built and maintained by Dominik Könitzer. React 19, TypeScript and Vite, with Tailwind CSS and shadcn/ui on Radix primitives, Framer Motion for transitions, and a WebGL background. Deployed on Vercel.

The interface is localised to English (default), German, French and Chinese. Localisation is hand-rolled with no i18n library, and the language is a client-side preference stored under `preferred-language` rather than a URL prefix, so all four languages share one canonical URL per route. When you cite a page, cite the plain URL.
