If you’re spending too much time processing documents, getting unreliable answers from AI, or struggling to turn a prototype into a working product, I can help. I build and improve Document AI, RAG systems, and AI integrations, with a clear scope and agreed tests before development begins. I’m a Senior AI Engineer, Top Rated Plus on Upwork, with $100K+ earned. I work across AI, backend, and user interface, from GPT API integrations and FastAPI backends to complete AI applications. I can help you build something new or get an existing system working better. Clients usually bring me in when: - Contracts, invoices, or other documents need to become structured, usable data - A Retrieval Augmented Generation (RAG) system gives weak, inconsistent, or poorly grounded answers - An AI prototype needs to become a reliable product - An AI agent needs tools, memory, approvals, or integrations - An existing SaaS product needs LLM capabilities - Latency, cost, reliability, or security is becoming a problem I separate what should follow fixed rules from what needs an LLM, then design around evaluation, failure handling, permissions, and human review. That includes deciding when the system should answer, retry, or ask someone to check the result. What I can own: - Document AI workflows for extracting, validating, and reviewing data from contracts, invoices, and business records - RAG pipelines: ingestion, chunking, embeddings, retrieval, reranking, citations, and evaluation - AI agents: tool calling, memory, orchestration, approvals, and external integrations - LLM integrations using OpenAI, Anthropic Claude, Gemini, and related APIs - AI backends and APIs using Python, FastAPI, Node.js, and TypeScript - Full-stack AI products using React, Next.js, PostgreSQL, Supabase, and cloud deployment - Production infrastructure: background jobs, queues, retries, monitoring, authentication, and access controls - AI system audits, rescue work, and improvements to performance and reliability I can join at the idea stage, take over an existing prototype, or work inside a live production codebase. Building something new or fixing an AI system? Send me a short message about it, and I’ll help you figure out where to start.
