FAQ
Do you only build with TypeScript, or can you work in JavaScript/Python too?
My primary stack is TypeScript and Node.js for maximum reliability and type safety, but I also work with Python — especially for scripting, scraping, and automation tasks. We'll agree on the right tool for your project once you message me.
Can you maintain or add features to an existing project instead of building from scratch?
Yes. Send me your current codebase or extension and I'll review it before quoting — pricing depends on the state of the existing code and how much rework it needs.
Will I own 100% of the source code after the project is delivered?
Yes. Once the project is delivered and paid in full, you receive complete ownership and the full source code, with no licensing restrictions or hidden dependencies on me.
What happens if I find a bug after you deliver the project?
Every package includes a post-delivery support window to fix any bugs tied to the agreed scope, at no extra cost. I don't disappear after the invoice is paid — if something breaks because of my code, I fix it.
What if my project doesn't fit neatly into one of the three packages?
Message me before ordering. Most custom or larger-scope projects — like combining a website, a backend, and automation into one system — are quoted individually as a custom offer, scoped to exactly what you need.
