You will get RAG Knowledge Base System | AI Engineer
Project details
Turn scattered documents into an AI-ready knowledge base that answers questions with cited, trustworthy sources.
PROJECT DETAILS
I turn your documents, wikis, and PDFs into a searchable, AI-ready knowledge base. Ask a question in plain language and get an accurate answer with the source it came from.
As an AI engineer, I handle ingestion, chunking, embeddings, the vector store, and a simple web UI. The system is built around your data so answers stay relevant and grounded, with citations that let your team verify every response.
This is a scoped, affordable version of the RAG reference architecture we use for larger clients — ideal for a first internal rollout to one team or department.

Projects I’ve led or contributed to have delivered measurable results:
✅ 50%+ less time per fintech risk assessment
✅ 30% higher patient adherence with an AI-powered healthcare platform
✅ 2× faster processing of historical energy data
✅ Customs declarations completed in under 90 seconds instead of hours
My main focus is production AI: LLM agents, RAG and knowledge systems, AI-powered workflows, data pipelines, API integrations, evaluation, monitoring, security, and scalable backend architecture.
💬 What Clients Say ⭐️⭐️⭐️⭐️⭐️
“Exceptional attention to detail and great team to work with!”
“Great professional, all tasks were completed on time. I would hire him again.”
🤖 AI Development & LLM Solutions
As an AI developer, generative AI developer, LLM developer, and AI agent developer, I build:
✔️ AI agents and multi-step AI workflows
✔️ RAG systems and AI-powered knowledge bases
✔️ OpenAI API and ChatGPT API integrations
✔️ LLM evaluation, monitoring, guardrails, and observability
✔️ Document processing and structured data extraction
✔️ Predictive automation and decision-support systems
✔️ AI features for healthcare, fintech, SaaS, and data-heavy platforms
I work with OpenAI, ChatGPT, Claude, Gemini, LangChain, Python, FastAPI, vector databases, embeddings, and external APIs.
💻 Full Stack Web Development
As a full-stack developer, full-stack web developer, and SaaS developer, I can take a product from architecture and prototype development through launch, optimization, and scaling.
➡️ Front end development: React, React.js, Next.js, TypeScript, JavaScript, Redux, Angular, jQuery, HTML, CSS, responsive UI, dashboards, and complex web applications.
We build modern, responsive user interfaces with React, TypeScript, JavaScript, HTML, and CSS, focusing on usability, clean architecture, and business goals as a fullstack developer, react developer with previous project manager and saas developer expertise.
➡️ Back end development: Node.js, Nest.js, Python (FastAPI / Django), . NET, PostgreSQL, MongoDB, Redis, microservices, Flask, back end developer node.js, backend engineer, Supabase
We design and optimize APIs, microservices, and system architectures using Python (FastAPI, Django, Flask) and Node.js (MERN stack), with a strong focus on scalability and performance.
We also handle full-stack migrations from Laravel to Django or FastAPI.
My experience as a React developer, Node.js developer, Python developer, backend developer, and full-stack software developer allows me to solve problems across the entire product architecture instead of treating each layer separately.
📱 Mobile App Development
I build cross-platform mobile applications using React Native and Flutter for iOS and Android.
As a React Native developer and mobile app developer, I have experience with:
☑️ Native device integrations
☑️ Firebase and push notifications
☑️ API-driven mobile applications
☑️ Healthcare and business workflow apps
☑️ App performance and maintainable mobile architecture
🏆 Selected Project Outcomes
