About this gig

Add real AI features to your existing product - built by a developer who ships production systems, not prototypes.


US-based senior developer. I integrate Claude, OpenAI, Gemini and open-source models (Ollama, vLLM) into web apps, mobile backends, SaaS products and internal tools.


WHAT I DO

  • AI features inside your app: summarization, generation, extraction, classification, smart search
  • - Streaming responses, function/tool calling, structured JSON output
  • - Fine-tuning on your data and prompt engineering that survives edge cases
  • - Cost and latency optimization: caching, batching, the right model for each task
  • - Secure key handling and rate-limit-proof architecture

ANY STACK

Python, Node/TypeScript, Next.js, React, REST or GraphQL backends.


WHY BUYERS PICK ME

  • Production quality: error handling, tests, and documentation included
  • - Honest scoping: I'll tell you exactly what your feature needs, and what it doesn't
  • - Clear communication and realistic timelines

Send me your repo or a description of the feature and I'll reply with an approach and a fixed quote.

US-based senior developer with 240+ completed Fiverr orders and a 5.0 rating. I build two things well: AI automation (custom agents, n8n/Make workflows, RAG chatbots trained on your data, integrations with Claude, OpenAI and open-source LLMs) and blockchain systems (coins on their own chain, tokens, smart contracts, presale dApps). Everything I ship is production-ready: tested, documented, and yours to keep with full source code. Message me before ordering and I'll scope your project honestly, even if that means telling you it needs less than you think.
