Hello, I’m Sonik

I build software end to end.

Software Developer working across full stack development, generative AI & LLMs, DevOps and cybersecurity, from the development to the deployment.

#about();

I started out as a commerce student, somewhere between balance sheets and broken CSS, and code won. I taught myself to build for the web and never really stopped.

These days I like owning the whole thing: the database, the backend, the UI, the cloud it lives on, and the lock on the door. Add an LLM to the mix and I'm happy. Hoodie on, keyboard ready.
