Want to add AI to an existing SaaS, web app, internal tool, or software product without rebuilding everything from scratch?
I can help design and integrate AI features directly into your existing product. From the user experience and backend architecture to model APIs, data flows, and production deployment.
Depending on your product, I can help with:
AI chat and assistants
LLM-powered product features
Document analysis and information extraction
RAG and knowledge-base search
AI-powered search and retrieval
Summarization, classification, and structured outputs
AI agents and tool-calling workflows
Content and workflow automation
OpenAI, Claude, Gemini, and other model/API integrations
Connecting AI to your existing databases, APIs, and business logic
Usage limits, reliability, latency, and cost considerations
I work across frontend, backend, APIs, databases, AI integrations, and software architecture, so the AI feature can become a real part of your product rather than a disconnected demo.
If you know the outcome you want but aren’t sure which model or technical approach makes sense, that’s completely fine. Send me a message with what your product does and what you’d like AI to accomplish, and I’ll help you work out a practical approach.
