Some of my recent thoughts

Building GoSpendl: A Bitcoin Product Search Engine, End to End

A product search platform for the Bitcoin community, built solo - the crawler that scales without burning LLM tokens, the realtime layer that broke on Vercel, the $5/month host that runs it all. Here's the whole build, and where it stands now.

Nuxt 4 WebSockets Are Elegant. Here's Why They Break on Vercel.

A first-hand debugging story — Nuxt 4's native WebSocket API is the cleanest I've seen in a full-stack framework, but the Nitro Vercel preset never implements the upgrade handshake. Vercel supports WebSockets fine; Nuxt's adapter for it just doesn't exist yet.

Migrating a Live B2B Platform to AWS Without Stopping the Business

A four-year migration moved a veterinary industry webshop off a legacy monolith onto an orchestrated AWS architecture, service by service, without ever pausing the live business.
Niklas knows his stuff, works reliably, and delivers high quality. I can highly recommend his services. He was an asset to our team, quickly familiarized himself with the technology and our development processes, and was thus able to work through tickets and tasks independently in a timely manner.

Niklas provided crucial support to our team in the further development of our SaaS product. With his expertise in full-stack development and his focus on front-end technologies such as Vue.js, he was a valuable asset. He always completed his tasks reliably and to our complete satisfaction. His proactive approach is particularly noteworthy: he critically questions approaches and contributes his experience to planning and implementation in a profitable way.

Over the past three years, I have enjoyed implementing new features and maintaining the existing system with Niklas. He is a helpful colleague who is interested in technology and open-minded. What I admire most about Niklas is his dedication to topics that have sparked his interest, such as pizza or Vue.
