Not available for work

Hi, I'm Donlawat.
I build things for the web.

Full-stack & backend developer with a strong foundation in C#, JavaScript, and Python. I'm comfortable across the whole stack — from designing databases and APIs to shipping polished frontends.

A bit about me

I'm a versatile full-stack developer with a strong foundation in C#, JavaScript, and Python. I'm highly adaptable and comfortable developing within diverse Linux environments — from Arch to NixOS — and I enjoy working across the entire stack, from database design and API architecture to building polished frontends.

Beyond work, I'm an independent tinkerer: I've built custom development tooling and dabbled in game modding, which has sharpened my ability to read unfamiliar codebases and ship independently. I'm deeply interested in the evolving landscape of artificial intelligence and actively exploring how generative AI can be integrated into modern software architecture.

I'm currently open to full-time roles and interesting freelance projects. If you're building something that needs a flexible and reliable engineer, I'd love to hear about it.
