Project details

You will get a production-ready LLM on your data — shipped in 7 days with evals, cost guardrails, and full ownership.

No generic AI fluff. I build retrieval-augmented generation (RAG) pipelines that answer in your tone, cite sources, and reduce hallucinations. Fine-tuning is included only if it beats baseline and pays off.

You’ll receive eval reports (accuracy, latency, cost), a deployable app (API or UI), full source code, and clear documentation. I work inside your cloud/accounts — no lock-in, no hidden infra bills.

If you want an LLM that works, not just “talks smart,” I deliver.

Digital Signal Programming Advanced Task Windows 10 Alex is a good DSP Developer he must have 5 stars for effort as he developed solutions in 24 hour windows and even worked on a project before he was hired for it this is someone who is great to work with. However with Alex you want a lot of details included specific task breakdown as much as possible recommend hiring the support of a Systems Developer or Systems engineer so task process is clear and to the point. Alex is solid and among the top guys for DSP programming on Upwork

Almaty, Kazakhstan - 3:13 am local time
Losing hours to manual work your tools should handle automatically? I build the AI agents, RAG chatbots and n8n automations that fix that — production systems that run 24/7, not fragile demos, with custom Python when no-code hits its limit. Across 33 jobs and 900+ hours on Upwork I've shipped systems that are still running in production today.

What I do:
• AI agents & RAG chatbots (OpenAI, Claude, LangChain)
• Workflow automation (n8n, Make, Zapier) + custom Python
• Web scraping & data extraction
• API integrations & backend (FastAPI, Django, PostgreSQL)

Message me or book a quick call — I'll tell you straight whether I can help and how I'd do it.
