FAQ
What information do I need to get started?
I need a clear description of your project goals, your dataset (if applicable), preferred tech stack, and any specific output format you expect. The more detail you share, the faster I can deliver.
Can you work with my existing codebase?
Yes. I can integrate new ML or LLM features into your existing Python project, API, or application without rebuilding from scratch.
What if I don't have a dataset?
I can help you identify publicly available datasets, scrape data, or use synthetic data generation depending on your use case.
Do you provide support after delivery?
Yes. I provide 3 days of post-delivery support for bug fixes and minor adjustments at no extra cost.
