You will get a custom OpenAI or Claude AI feature integrated into your app or API
Project details
Want to add AI to your product but don't have time to wrestle with the OpenAI or Claude API? I build the feature and hand it back working, tested against your real data.
You describe the outcome — "summarize support tickets", "extract fields from PDFs into JSON", "answer questions from our docs", "draft replies in our tone" — and I wire up GPT or Claude to do exactly that, in your stack.
What I deliver:
• Working code in your language (Python, Node/TypeScript, Next.js, FastAPI, or a serverless endpoint)
• Prompt engineered and tested on your real examples, not guessed
• Structured, predictable output (validated JSON when needed), not a wall of text
• Guardrails: your key in env vars, token/cost limits, input validation, auth on the endpoint
• A README and (Standard+) a Loom walkthrough so you or your team can run and deploy it
Best for self-contained features where you provide the key, a few examples, and the repo or stack. Needs live CRM/database access or a long retainer? Message me first and we'll scope it.
New to Upwork, so this is priced to earn my first reviews — senior work at an intro rate. Tell me the outcome you want and I'll tell you exactly how I'd build it.

About Tony
AI Agent & MCP Engineer | RAG, LLM Integration, Full-Stack AI Apps
Alpharetta, United States - 11:17 pm local time
I'm a US-based, code-first AI engineer (Nexus Digital Group). Real systems I've shipped:
- A 26-agent autonomous marketing department on the Claude Agent SDK (Next.js, compliance hooks) running across 7 coordinated departments
- A conversational pricing assistant wired to a LIVE MCP server, with an agentic workflow and guardrails
- A citation-backed RAG chatbot that grounds every answer in your docs and never fabricates (Vercel AI SDK + Claude)
- A PDF-to-JSON extraction API — stateless, schema-validated, Claude-backed
- A multi-tenant AI SaaS app (Next.js/Supabase/Stripe) and a digital origination platform with 15+ third-party API integrations
What I deliver:
- AI agents & MCP servers — multi-agent orchestration, tool use, guardrails, the Claude Agent SDK
- RAG chatbots — citation-backed, grounded in your docs, built so they don't hallucinate
- Full-stack AI apps — Next.js / TypeScript / React, Supabase, Stripe, plus React Native mobile
- Custom LLM & API integrations — OpenAI/Claude wired into your stack, your data, your auth
- Document & data extraction — PDF/Excel to clean, schema-validated JSON
How I work:
- Fixed price, scoped clearly up front — you know the cost before I start
- Same-week turnaround on most well-defined builds
- Every delivery includes a Loom walkthrough and a setup doc so you can run it yourself
- Tested against your real data before handoff — not a happy-path demo
Stack: Next.js, TypeScript, React, Node, Python, OpenAI/Claude APIs, LangChain, vector DBs, Playwright, Supabase, Stripe, React Native.
No Upwork reviews yet — I'm building my track record, so you get senior-level engineering at $35/hr and someone motivated to over-deliver. Send me what you're trying to build and I'll reply with exactly how I'd build it, a fixed price, and a realistic timeline.

Scope the feature & output
I confirm exactly what the feature should do and what 'good output' looks like, using your real examples.
Build it in your stack
I wire up GPT or Claude in Python, Node, or Next.js, with validation, guardrails, and your key in env vars.
