Refactoring 370 Files in 11 Hours (thanks Claude)

What happens when you need to refactor 377 files in a SvelteKit codebase? Without AI, you retire. With Claude Code, you ship it in 11 hours.

This talk walks through real-world examples of using Claude Code for massive refactoring work that would be soul-crushing to do manually. I'll cover:

  • How I approach large-scale refactors with Claude (377 files → 364 files → and counting)

  • Building and activating Claude Code skills reliably (based on my viral post that's getting 4k+ views in 3 days)

  • The workflow patterns that actually work vs the ones that waste your time

  • Real examples from production codebases

This isn't about AI replacing developers - it's about using AI to handle the tedious parts so you can focus on the interesting problems.

AI Bubble Round Table

A discussion what would happen if the AI Bubble bursts - Positive vibes through out...

Multiplayer Xmas (Geo)-spatial Supabase Edition

The Supabase and Google Maps edition of Multiplayer Geospatial Xmas Fun Special! Join a festive demo where we build a realtime Christmas treasure hunt using Supabase and Google Maps. Players join via QR, drop guesses on the map, and watch the heatmap light up as everyone races to find Santa’s lost present. We’ll peek behind the scenes at realtime channels, Edge Functions, geospatial queries, and a few helpful Google Maps features you can use in real apps.

Turning Downtime into Build Time: Lessons from Creating an AI-Powered Side Project //

After being laid off from my previous company, I decided to take the downtime as an opportunity — “Maybe it’s time to build a product that actually solves my own problem.”
That’s how Monthly Grow started.

I tend to be quite spontaneous — diving into whatever catches my curiosity at the moment.
Naturally, routine and long-term planning have never been my strongest suits.
So I wanted to create a tool that would help me plan, track, and reflect on projects in a way that fits me, with minimal friction and some help from AI.

I also wanted a technical challenge.
I implemented features I couldn’t try at work and explored how powerful this new “vibe coding” trend really is.
Designing the structure and data flow from scratch was a first for me — and I ended up rebuilding everything three times.

It was a fun and rewarding process, though I’m not confident enough to call it “production-ready” yet.
Maybe the most productive next step is to release it publicly and learn from real users — even if that means enduring some brutal star ratings.

It’s been a month since I settled in London, and I’m finally getting used to my new life.
Now I’m asking myself: Should I keep developing Monthly Grow? Start a backend-focused practice project? Or try building an AI + vibe coding product with real monetization potential?

If you’re working on something similar or just interested in chatting about side projects and AI tools, I’d love to grab a coffee or hear your thoughts in the comments. ☕
