About this gig
Already have a SaaS or web app and want AI that feels like part of the product not a bolted-on chatbot?
I'm a full-stack software engineer with 4 years of experience building SaaS, marketplace, fintech, booking and real-time products.
I integrate OpenAI, Claude and Gemini directly into existing applications across the full product flow UI, backend, data, authentication and error handling.
I can build AI assistants/copilots, summarization, extraction, classification, structured outputs, document workflows, smart search, content features and custom AI workflows.
Depending on the feature, I can also implement streaming responses, conversation history, database context, tool/function calling, usage controls, retries and validation.
Please message me before ordering Standard or Premium with your current stack and the AI feature you want to add.

I'm a full-stack software engineer with 4 years of experience building and improving SaaS products, marketplaces, booking systems, fintech platforms and real-time applications. I work across React, Next.js, Node.js, APIs, databases, authentication, payments, AI-powered features and third-party integrations. I've built products from scratch and worked inside large existing codebases to debug, extend and ship complex functionality. If you have an idea, unfinished SaaS, broken app or integration problem, send it my way.

FAQ
Can you integrate OpenAI, Claude and Gemini?
Yes. I can integrate API-based features using OpenAI, Anthropic Claude, Google Gemini and compatible providers depending on the product requirement.
Do I need my own AI API account/key?
Yes, the production API account should belong to you. We can begin with a test/development key or provider access appropriate for the project.
Can you add AI to an existing React/Next.js/Node application?
Yes. That is the main purpose of this Gig: add the AI feature inside an existing product rather than rebuild the product around AI.
Can you build RAG or a knowledge-base assistant?
Yes for suitable scopes, but RAG depends heavily on the data source, retrieval method and expected quality. Please message me first so I can scope it correctly.
Can you build AI agents?
Simple tool-using or multi-step AI workflows can be scoped. Larger autonomous-agent systems, complex orchestration or external automation platforms should be reviewed as a custom project.
Can you guarantee the model will always be accurate?
No AI model is perfectly accurate. I can improve reliability with better prompts, structured outputs, validation, retries, context and product guardrails, but the product should still be designed around model limitations.
Can you reduce AI usage costs?
Yes. Depending on the feature, I can help with model selection, shorter context, usage limits, caching/flow design and avoiding unnecessary calls.
What counts as a revision?
A revision adjusts the agreed AI feature. A new workflow, new data source, additional model provider or unrelated feature is additional scope.
