# I Will Build a Custom AI Microservice or Chatbot Solution

Your business deserves AI that actually works — not a demo, not a proof of concept, but a production-ready microservice or chatbot integration you can deploy and rely on.

Whether you need a GPT-powered assistant, a Gemini integration on Google Cloud, a LangChain agent, or a custom API pipeline connecting your product to the latest [large language](https://zinnhub.com/zinns/integrate-large-language-models-into-your-project-with-zinn-digital/) models, this service delivers functional, tested, source-code-included AI solutions built to your requirements.

\*\*What you get:\*\*
 Every engagement starts with thorough research into your use case and the most appropriate model or API for the job. From there, the work covers fine-tuning prompts and model behaviour, integrating the chosen API cleanly into your stack, and handing over full source code you own outright. Higher tiers add data preprocessing, model documentation, validation and testing, and performance monitoring — so you can scale with confidence.

\*\*Technologies in use:\*\*
 OpenAI (GPT), Google Gemini, Vertex AI, GCP, AWS, LangChain, Langfuse, LlamaIndex, Llama 2, Autogen, TensorFlow, PyTorch, and no-code workflow tools including Flowise, N8N, Langflow, and Zapier — applied where each is genuinely the right choice for your project.

\*\*How it works:\*\*
 After you place your order, share your project details via the order chat. The clearer your brief, the faster the build. If more information is needed, you will be contacted directly through the order. Delivery is structured, milestone-driven, and communicated throughout.

\*\*Who this is for:\*\*
 Startups and scale-ups integrating AI into their product for the first time. Development teams that need specialist AI engineering support. Founders building AI SaaS applications. Businesses exploring blockchain-plus-AI workflows. Anyone who wants working code, not a slide deck.

\*\*Why Zinn Digital:\*\*
 Based in London, Zinn Digital brings together AI engineering and full-stack development under one roof. Solutions are built using industry-leading libraries and cloud platforms, rigorously tested for performance and reliability, and developed collaboratively — your vision drives the process from first message to final delivery.
