About this gig

ABOUT ME


I build complete AI-powered products not just API wrappers. From the prompt engineering and LLM orchestration layer, through the backend pipeline, to a polished frontend your users can actually interact with. 


WHAT I CAN BUILD


  • RAG systems: crawl or ingest your content, retrieve it intelligently, and feed it to an LLM
  • AI chatbots and assistants
  • Image generation pipelines
  • AI-enhanced workflows: document processing, summarisation, classification, extraction, translation
  • Structured output systems: LLM-generated JSON, form auto-fill, data normalisation
  • AI agents: multi-step reasoning, tool use, web search integration, task automation
  • Prompt engineering and LLM orchestration
  • Vision model integrations: image understanding, OCR, layout analysis, visual Q&A
  • Voice and audio pipelines
  • Semantic search: vector databases, hybrid retrieval
  • AI-powered content tools


And more


******CONTACT ME BEFORE YOU ORDER FOR CLEAR UNDERSTANDING******


If your product idea has an AI component whether it's a chatbot, an image tool, a document processor, or something more custom I can build the full thing end-to-end. Message me with what you're trying to build.

Full-Stack Engineer specialized in blockchain, Web Applications, AI-powered applications, and workflow automation. I build complete products end-to-end, from smart contracts and Web3 backends to SaaS platforms, Web Applications, LLM integrations, and n8n automations. With 4+ years of professional experience, I've shipped production systems for international clients including a multi-tenant AI SaaS platform, NFT game backends, real-time multiplayer apps, and fractional ownership dApps. I work async across time zones, communicate clearly, and deliver work that's built to last, not just to demo.
