I will integrate openai api, chatgpt api, claude api and rag into your saas
Atif Ali
Acerca de este Servicio
Senior engineer who shipped Axon, a multi-tenant SaaS with Claude and OpenAI both in production with multi-LLM routing.
I integrate AI APIs into your existing app the way you would actually want it: structured output with strict validation so responses fail loudly when malformed, idempotent retries on rate limit and timeout, prompt engineering tuned to your domain.
Full observability on every call so you see latency, cost, and outputs. RAG pipeline with hybrid retrieval, re-ranking, and citations to your real content.
Premium tier adds multi-LLM routing with fallback, cost tracking per request, and per-tenant quota management.
Send me your stack and the AI feature you want; I handle the wiring end-to-end.

Stack: Laravel, React, Python (FastAPI), Node.js, Golang, PostgreSQL, Redis, Docker, AWS.

FAQ
Claude or OpenAI which one?
Both supported. Claude is stronger at long-context reasoning, structured output, and tool use; OpenAI is stronger at code generation and lower-latency conversational tasks. I help you pick based on the actual use case, or use multi-LLM routing on Premium tier.
What is RAG and why include it?
Retrieval-Augmented Generation grounds the LLM in your data instead of relying on its training cutoff. Standard tier adds RAG over your documents so the AI cites your real content, not generic responses.
How do you handle costs and rate limits?
Premium tier includes cost tracking per request (per-tenant if multi-tenant), per-user rate limiting, and idempotent retries on rate limit errors. You see exactly what each AI call costs and stop runaway bills.
Do you sign NDAs and protect API keys?
Yes, NDA before any access. API keys are passed via runtime environment or your secret store; nothing lands in the repository or the deployed image. I do not retain credentials after handoff.
What stacks do you integrate with?
Laravel, FastAPI, Next.js, Express, Node.js, Django, Rails. Integration is via REST or your existing service layer; no rip-and-replace required.
