About this gig
Want AI that does real work inside your product, not just a chat box? I add LLM features to existing web apps and business software.
I build AI in production every day: an assistant inside a CRM/ERP that creates and edits records after user confirmation, AI-written reports sent automatically, and an email assistant that drafts replies with a confidence score.
What I can add to your app:
- AI assistant / chat that reads your data and runs actions (function calling)
- Summaries, classification, data extraction and text generation
- OpenAI, Claude or open-source models, behind your own API
- Safe limits: confirmations, permissions, logs and cost control
Stack: Angular, TypeScript, Node.js/Express, Python, MySQL, REST APIs. I also work with React and PHP backends.
Not sure what fits your case? Send me a message before ordering and I will suggest the simplest option that works.

FAQ
Which AI provider do you use?
OpenAI, Anthropic Claude or open-source models (Llama, Mistral, Qwen…). I recommend one based on cost, quality and privacy. API usage costs are paid by you directly to the provider.
Can the AI change data in my system?
Yes, through controlled actions. By default every write action asks the user to confirm before it runs.
Do you work on my existing code?
Yes. I need access to the repository or a copy, and a test environment.
Which languages and frameworks?
Angular, Node.js, TypeScript, Python and PHP. Other stacks: ask me first.
