FAQ
Do you build simple chatbots & LLM integration or complex AI systems?
I specialize in building production-ready AI systems including custom AI agents, multi-agent orchestration, advanced RAG/GraphRAG pipelines, and enterprise search platforms. If you need scalable AI infrastructure rather than a basic chatbot, this gig is ideal for you.
Can you work with my existing tech stack and data sources?
Yes. I integrate AI systems into your existing architecture, including web applications, SaaS platforms, cloud storage, and CRMs. I build secure data ingestion pipelines and custom MCP servers to safely connect your internal databases and legacy systems with modern, powerful LLMs.
Which LLMs and databases do you work with?
I work with OpenAI models, Gemini Models, Claude Models, open-source LLMs, embedding models, vector databases, graph databases, relational and NoSQL databases. I design hybrid search architectures combining vector, graph, and metadata-based retrieval depending on your use case.
Do you provide scalable and secure enterprise-ready solutions?
Yes. Every system is built to enterprise standards with multi-tenant security, strict data privacy controls, and optimized backend code. The architecture is stable, secure, and designed to scale as your business grows.
Do I need to contact you before placing an order?
Yes, please message me prior to ordering. AI developments are highly customized and depend on your specific technical requirements. Discussing your data structure, system architecture, and project goals beforehand ensures we align on the correct engineering approach from day one.
