You have an app, a CRM, a mailbox or a spreadsheet. I add the AI feature you need (summarise, classify, extract, draft or answer) using OpenAI or Claude, wired into your existing system and built to be safe, predictable and affordable.

This is for you if • Your team reads, sorts or summarises the same kind of text every day • You want to pull structured data out of e-mails, forms or documents • You'd like AI-drafted replies that a person checks before sending • You tried ChatGPT by hand and now want it built into your workflow

What you receive • One AI feature wired into your system: your app, API, database, CRM, e-mail or Google Sheets • Validated, structured output (clean JSON fields), so your system can use the results directly • Personal data masked before any text is sent to the AI provider • Retries, timeouts and limits on call size and number, so costs and errors stay under control • Prompt-injection defences and strict checks on everything the model returns • Full Python source code (FastAPI), automated tests, Docker and a setup guide

AI features I can add • Summaries: long e-mails, tickets, calls, reports or documents in a few clear lines • Classification and routing: tag, prioritise and route messages, leads or tickets automatically • Extraction: names, dates, amounts and other fields from e-mails, forms, invoices or PDFs into your database or spreadsheet • Drafting: suggested replies, product descriptions or reports, reviewed by a person before sending • Search and Q&A: answers from your own data or documents, with sources • Sentiment and trends: spot unhappy customers, unusual activity or changes over time • Your choice of model: OpenAI or Claude, swappable later without rewriting your app

You tell me your system, the feature you want and share a few real examples.

I send a written plan: input, output format, safety rules, expected cost, and what's in and out. Nothing starts until you approve it.

I build the feature and test it on your examples, including edge cases and messy inputs.

We connect it to your live system together.

You receive the code and the guide, and I make your changes.

Proof you can check NexusFlow, my open-source AI automation platform, uses Claude to summarise and explain business changes, with personal data masked before every AI call, validated output and a provider layer that lets the model be swapped. It has 2,561 automated tests at 90% coverage. https://github.com/mojtaba-py-code/fastapi-postgres-ai-automation-platform

My AI document assistant and AI support platform add answers with verified sources, prompt-injection screening and daily cost budgets, with 1,746 and 484 automated tests. https://github.com/mojtaba-py-code/ai-document-assistant

Not included Training a custom AI model from scratch, Make or Zapier builds, hosting fees, and AI usage costs (billed to you directly by OpenAI or Anthropic).
