Erik Nilsen

AI Enthusiast & Backend Developer

I get AI to write the code, so I don't have to. Node.js, TypeScript, Azure and a healthy dose of prompt engineering. IT support for those who need it, and consulting for those heading to the cloud.

// About me

I'm a backend developer and systems administrator with a passion for building and running services that people actually use day to day. My background is in IT support and customer service, and that's shaped how I work as a developer — I build with the end user in mind and know exactly how much stable uptime matters when something has to work 24/7.

On the technical side, I have solid experience with Node.js and TypeScript, relational databases like PostgreSQL, and caching/background jobs with Redis. I'm integrating with third-party APIs constantly — payment providers, accounting systems, email providers and AI services — and I'm comfortable running, securing and monitoring production environments.

I also have broad experience with Microsoft Azure, Microsoft 365 and PowerShell automation. Certified in Azure Fundamentals and Microsoft 365 Fundamentals, with a Norwegian trade certificate in IT services and further education in cloud administration.

The last few years, I've swapped the keyboard for well-crafted prompts. I pay $200/month for Claude Code Max and burn through about $2000/month in API tokens. I've got 10-15 terminals open working for me at once — when they're done, they check each other's pull requests and fix things. I've basically become manager for a gang of AI developers.

In my spare time, I'm what some would call a real domain shark. I own around 100 .no domains at any given time, keep a close eye on the market, and love hunting for good names before anyone else gets there. It started as a hobby and became a natural extension of my interest in the web and the Norwegian domain landscape. Some people collect stamps, I collect domains.

Fuel? Battery Blueberry — a Norwegian energy drink that's basically blue rocket fuel in a can. Some people run on coffee, I run on blueberry-flavored ambition and a couple thousand milligrams of caffeine a week. No cause for concern here.

What I like best is the intersection of code, operations and customer experience. Just as important as the technology are the people around it — good collaboration, clear communication and a positive tone day to day. (Yes, this text was probably also partly AI-generated.)

// Things I've built.. or helped build

Regnskap MCP

AI that does your bookkeeping – with a safety net. A cloud-based MCP server that lets Claude, Cursor and other AI assistants manage your accounting in Fiken on your instructions. You approve every action, everything is logged with full traceability, and anything can be undone with one click (per Fiken's rules). OAuth2 means passwords are never shared, and the AI never acts on its own – you're always in control.

MCPAIFikenOAuth2SaaS
Brainrot Tycoon Clicker

My first mobile app! A tap-the-brain clicker/idle game packed with brainrot-meme energy. 25+ absurd characters (Serpentini, Tralalero, Ballerina Cappuccina), a prestige system, golden spawns, daily login streaks and passive offline earnings. Free-to-play with no pay-to-win. I own and build the whole thing myself – from game mechanics to distribution.

React NativeExpoMobile GameIdle/Clicker
Kroni.no

A family app for allowance and chores – no real money involved. Parents create tasks with a virtual value, kids complete them and save up toward rewards (screen time, movie night). GDPR-friendly with no tracking. Freemium with in-app purchases for extended use. An educational tool for teaching kids (ages 6-14) financial responsibility. Launching in Norway, Sweden and Denmark – translated into Norwegian, Swedish, Danish and English. We own kroni.no, kroni.se and kroni.dk.

A Norid-accredited domain registrar – quality over quantity. Built the entire EPP connection, backend API and infrastructure from scratch.

123Deksel.no

Frontend has never been my great passion (I lowkey kind of hate it), so I got a lot of help from AI. Claude and Cursor actually made Next.js development fun. Design your own phone case and get it shipped in incredibly short time! Now discontinued.

Because who actually has their receipts in order? Now you can. A FENO AS project built while I was searching for a receipt I never found.

Wow. This was really just a small experiment... but it ended up as an actual product. Built in 32 minutes – from npx create-next-app to a finished service. Paste the FINN listing link, get a PDF receipt. All client-side – zero stress.

AI voice agents in practice! Call and talk to different AI characters – from Santa Claus himself to an energetic motivational coach. A fun experimental platform guaranteed to put a smile on your face. Shut down due to high voice-agent costs and a lack of time for further development – but a fantastic learning project!
