Freelancer profile translated to English.

Description

I'm Killian, a full-stack developer specializing in Svelte 5 (Runes) and SvelteKit. At 23, I created Nabu (@aionbuilders/nabu), a modular, local-first, collaborative block editor engine (single contenteditable + Loro CRDT). The project is mentioned in the official 'What’s new in Svelte' newsletter of May 2026.

My favorite stack:

Frontend: Svelte 5, SvelteKit / React when needed
Backend / Fullstack: Bun, Hono, SurrealDB / Node, Mongo, Postgres, Express when needed
Others: local-first, CRDT, real-time, web performance, light DevOps (Docker, etc.)

I've been a micro-entrepreneur since April 2025 and can invoice immediately.

I mainly work 100% remotely on projects ranging from 2 weeks to 3-4 months.

What I offer:

Creation or redesign of rich content editors (strong Nabu asset)
Development of high-performance and modern SvelteKit applications and websites
Rapid prototyping or MVP with Bun + SurrealDB
Migration / optimization to Svelte 5
Internal tools, dashboards, productivity SaaS, AI interfaces

If you're looking for a developer who truly masters Svelte 5 (not just a converted React dev) and knows how to architect modern, high-performance solutions, let's talk.

Available immediately.
