Indie tool builder · UX-focused developer · Local-first enthusiast
I build software because I want it to exist.
Mostly tools, apps, and systems that value clarity, user control, and long-term usefulness over trends. I’m skeptical of SaaS-by-default, allergic to unnecessary accounts, and deeply interested in software that works offline, locally, and on the user’s terms.
By day I work in IT support at Elkjøp Halden.
By night I build things I wish already existed.
A completely free, local-first accounting-lite app.
- No accounts
- No cloud
- No SaaS
- Full data ownership
Send and manage invoices, track expenses, and keep control of your own data. Built for people who don’t want their finances trapped behind a login screen.
A modern file manager for Linux.
Focused on:
- clean, intentional UX
- speed and clarity over feature bloat
- small, tasteful AI assistance where it actually helps
Not trying to reinvent files. Just trying to make them less annoying.
A job application tool with responsible AI use.
- No auto-rejections
- No fake “AI decided” excuses
- Strong emphasis on human accountability and transparency
Built around the idea that applicants deserve to be treated like people, not spam.
A developer tool aimed at reducing terminal dependency.
Provides a sleek, organized UI for common workflows that normally live in shell commands. Designed to lower friction without hiding what’s actually happening.
A deliberately silly app that judges your repositories.
Repos are treated as dead or dying projects, complete with:
- autopsy reports
- personality-driven commentary
- varying degrees of brutality
Built mostly for fun. Surprisingly good at making people reflect on abandoned code.
A 2D game engine written in Rust.
- Engine core in place
- Editor in progress
- Long-term exploration project
Less about shipping a Unity killer, more about learning engine architecture the hard way.
- Tool-first, product-minded
- Strong UX bias
- Local-first and offline-capable by default
- Minimal magic, explicit behavior
- Software should respect the user’s time and data
I enjoy owning the whole thing: data model → logic → UI → packaging.
Frontend
- React, Vite, Next.js
- Tailwind CSS, Framer Motion
Backend
- Node.js, Express
- MySQL / MariaDB
- REST APIs, auth, background tasks
Desktop & tooling
- Electron, Tauri (case by case)
- Local storage, IndexedDB
- Cross-platform packaging
Infra
- Linux
- Apache
- DigitalOcean
- Git & GitHub Actions
GitHub is a mix of:
- portfolio
- product distribution
- open-source experiments
Some projects are public, some are private, and not everything I build lives here.
