I will build ai web app, ai saas, ai agent and ai software development

Yes, and this is how most projects start. Send me the problem in plain language, what happens today and what you want to happen instead. I will come back with a scope, a recommended package and a fixed price. If I think the work is smaller than you expected, I will say so.

OpenAI, Claude, Gemini and open source models, plus vector databases such as Pinecone, Qdrant and pgvector. On the app side, Python, React, Next.js, Node and PostgreSQL. I pick the model that fits your budget and accuracy needs, not the one that is trending.

You own everything. Source code is included in every package, in a normal repository with a readme, environment file and setup steps. No hidden platform, no monthly fee to me, nothing that stops another developer picking it up.

Yes. That is most of what I do. Databases, spreadsheets, PDFs, CRMs and APIs. I come from six years of data and analytics work, so connecting messy real sources and getting sensible answers out of them is the part I am strongest at.

Bugs in what I built are fixed free for 14 days after delivery. Revisions are included per package. If you want ongoing changes after that, I offer a monthly retainer, but it is optional and you are never locked into it.
