Hire the Best GPT-J Specialists

Most people building AI products right now are stuck at the prototype stage. The chatbot works in a notebook, the agent runs on a laptop, and then it hits real traffic and falls apart. That gap between demo and production is exactly where I work. I spent the last few years as the lead AI engineer at a KYC company where the system could not afford to fail. 100,000+ identity verifications a day, enterprise clients in regulated industries, strict SLA requirements. I built and ran the entire AI pipeline there: document OCR, computer vision models, LLM-based extraction, the inference infrastructure behind all of it. At one point I took the GPU bill from $20K/month down to $7.5K without touching accuracy, just by rearchitecting how LLM inference was served. That kind of work teaches you to think about AI very differently than someone who has only ever built demos. Right now I am focused on freelance AI projects. Specifically: ✔️Chatbots that actually work: RAG-powered, grounded in your data, not hallucinating nonsense. Built with GPT-4o, Claude, or open-source models depending on your budget and privacy needs. ✔️AI agents that do real things: browse, search, write, call APIs, make decisions. Not just a prompt chain. Actual autonomous workflows using LangGraph, CrewAI, or AutoGen. ✔️LLM backends that scale: if you have something working small and need it to handle real load without breaking the bank, that is a problem I have solved before. ✔️Domain-specific AI for fintech, healthcare, and edtech: I have built financial dashboards with AI insights, patient management systems, and adaptive learning tools. I understand the constraints in each of these spaces. I do not take on work I cannot do well. If you send me a project and it is not a fit, I will tell you. If it is a fit, I will move fast, communicate clearly, and deliver something you can actually use. If you are building something real in AI and need someone who has been in the engine room of a large production system, let's talk.

Need AI added to your app, a workflow automated, or an MVP finished? I can help you scope it, build it, and ship it without overcomplicating the first milestone. I build AI products that survive real users, real data, and real business workflows: SaaS MVPs, AI agents, RAG systems, voice AI, and automation inside existing products. ⭐ Top Rated Plus | Top 3% of performers on Upwork ✅ 10+ years building SaaS and AI products | 100+ projects delivered ✅ AI that ships: RAG, AI agents, MCP, Voice AI, LLM integration ✅ Full stack: Next.js, React, TypeScript, Python, Node.js, PostgreSQL, AWS ✅ SaaS, MVPs, automation, fintech, healthcare, construction, legal tech, and sales products You can hire me when: - You need one AI feature added to an existing app - You want OpenAI, Claude, Gemini, or MCP integrated into your product - You need a RAG system over PDFs, documents, knowledge bases, or internal data - You want a voice AI agent for calls, bookings, lead qualification, or CRM updates - You have a workflow involving documents, calls, follow-ups, data entry, or reporting that should be automated - Your MVP is half-built, buggy, slow, or stuck before launch - You need someone to build a full SaaS product from idea to deployment I work well on both small and large projects. If the right first step is a quick audit, prototype, bug fix, integration, or one-week milestone, I will tell you that. If the project needs a full build, I can own the architecture, frontend, backend, AI layer, deployment, and documentation. The part most AI freelancers skip: AI is rarely the whole product. It usually needs a backend, dashboard, auth, billing, permissions, logs, human review, and deployment around it. I build both the AI layer and the product around it. WHAT I DO: - AI SaaS & MVP builds: idea to deployed product with auth, billing, dashboards, and AI layer - AI inside existing products: RAG, agents, MCP, LLM features, document AI, and automation - Voice AI: agents that answer calls, book appointments, qualify leads, and log to your CRM - RAG and document AI: source-grounded answers, OCR, extraction, citations, and review queues - Workflow automation: documents, follow-ups, data entry, reporting, and API integrations - Rescue & ship: half-built MVPs refactored, hardened, and launched RECENT DELIVERIES: - AI sales CRM: call transcription, follow-up automation, multi-tenant pipelines - RAG document platform with every answer cited to source - AI financial intelligence platform: open banking + accounting sync into one ledger - AI voice agents for healthcare and sales, answering real calls daily - Turnkey B2B SaaS platform for the construction industry, end to end HOW I WORK: - I start by understanding the workflow, users, data, and business goal - I suggest the smallest useful first milestone when possible - I scope clearly before code is written, so you know cost and timeline up front - I can work on focused tasks, short prototypes, rescue work, or full product builds - I work full time on Upwork with overlap for US and European business hours If you need one AI feature, a quick prototype, a stuck MVP fixed, or a full SaaS product built, send me a short description of what you have and what you want it to do. I will reply with the clearest next step, the likely scope, and the first milestone I would recommend.
