Hello, I’m Sondre.

AI, code and everything in between

I've spent years working at the intersection of artificial intelligence, decentralized systems and user-facing software. Whether it's orchestrating LLMs, fine-tuning prompts, shipping full-stack apps or exploring what comes after Web3, I love turning complex ideas into simple, delightful products.

The web is changing fast. AI is no longer a demo — it's the new interface layer. I help teams navigate that shift: from prototype to production, from experiment to reliable system.

What I'm working on

Nostria — a social network built on open protocols, with AI woven into the experience.

Polytalk.Me — learn the basics of many languages.

What I'm proud of

Built a Web5 wallet with support for multiple cryptocurrencies, tokens, identities (DID), NFTs and more.

Developed a friendly, feature-rich Nostr client. Nostr is a simple, open protocol that enables a truly censorship-resistant and global social network.

Co-founded Blockcore, an open source community building decentralized software — from atomic swaps to trustless funding on Bitcoin.

Working on the Free City Platform, open source tools for running free cities.

What I'm looking for

I want to work on software that matters — ideally full time on open source and AI. I'm open to opportunities, sponsors and collaborators who share that goal.

If you're building with LLMs, agents, decentralized tech or the next generation of web applications, I'd love to hear from you.

How I work

I care about craft. Good architecture, clear UX and code that survives contact with reality. I'm a quick learner, a team player and — according to the people I work with — someone who brings positive energy to a project.

I've worked remotely for years and thrive in distributed teams. I'm comfortable anywhere from early prototyping to production systems at scale.

I also love sharing what I learn through writing, speaking and open source.

Tools & technologies

Languages, frameworks and ideas come and go. What stays is the ability to learn and adapt. Lately I'm especially drawn to:

AI / LLMs, Prompt Engineering, Agents, TypeScript, JavaScript, Node.js, Python, C#, .NET, ASP.NET, Web3, Web5, Nostr, Bitcoin, Ethereum, Docker, Kubernetes, Azure, MongoDB, RocksDB, Tauri, Electron, PWA, DevOps, Git, GitHub, VS Code.
