About this gig

I add Claude or OpenAI capabilities to products that already exist - your app, your internal tool, or your workflow - without you having to rebuild anything from scratch.


Recent example: FilingIQ, a financial-document assistant where I integrated the Claude API into an existing FastAPI backend to generate citation-grounded answers over SEC/NSE/XETRA filings, including a two-company comparison mode and streaming responses.


What you get:

  • The LLM wired into your existing app/endpoint, not a new app built from zero
  • - Prompt design tailored to your use case, with structured/JSON output if you need it
  • - Streaming responses if your UI needs them
  • - Sensible error handling so a bad API response doesn't break your app
  • - Clean, documented code

Tell me what you're building and what you want the AI to do, and I'll tell you honestly whether it's a Basic, Standard, or Premium job before you order.
