AI Solutions: Custom AI Development, Integration & Training

Vintage Coding LLC builds custom AI solutions for businesses, including AI chatbots and agents, custom GPT and LLM development, Retrieval Augmented Generation (RAG) pipelines, and AI-powered workflow automation.

AI That Solves Real Operations & Product Needs

Services also include API and system integration connecting AI to existing CRM, ERP, and database platforms. We focus on production-ready AI systems rather than one-off demos, with an emphasis on prompt engineering, reliability, and selecting the right model or tool for each use case.

What We Build

Custom AI Applications

Purpose-built AI tools and products designed around your specific business logic, data, and users, not a generic wrapper around ChatGPT.

AI Chatbots & Agents

Intelligent, multi-step agents that reason, act, and integrate with your existing systems to automate complex tasks without constant human input.

Custom GPT & LLM Development

Fine-tuned language models and custom GPT configurations trained on your internal data, your brand tone, and your specific workflows.

RAG Pipeline Development

Retrieval Augmented Generation systems that connect AI models to your internal documents, databases, and knowledge bases for accurate, grounded responses.

AI Workflow Automation

AI-powered automation built with n8n, Make, and Zapier that eliminates manual processes and connects the software tools your business runs on.

API & System Integration

Connecting AI models and services to your existing CRM, ERP, databases, and third-party platforms so everything works as one system.

How We Build It

The Right Model for the Right Job

Not every problem needs a massive LLM. Not every solution needs a custom model. We evaluate your use case honestly and select the right combination of tools, models, and platforms, so you're not overpaying for complexity you don't need.

Production-First Thinking

A demo that works once isn't a solution. We build AI systems with reliability, security, and maintainability in mind from day one, because what breaks in production costs far more than what breaks in a pitch.

Prompt Engineering That Actually Works

Weak prompts produce weak results. We design, test, and optimize the system instructions and prompt chains that power your AI, reducing hallucinations and ensuring predictable behavior at scale.

Who This Is For

  • • Business owners who know AI can help operations but need a trusted partner to start.
  • • Startups building AI products needing a technical partner to move fast securely.
  • • Teams using AI tools inconsistently and needing training and structured workflows.
  • • Enterprises integrating AI into existing systems requiring senior architecture guidance.

Why Work With Us

With 25 years across software engineering, enterprise architecture, and AI development, every engagement benefits from senior-level thinking, not a junior handoff after the first sales call.

We also train you. We offer hands-on training so your internal team can manage, extend, and grow your AI capabilities long after the project ends.

Frequently Asked Questions

Custom AI application development is the process of designing and building an AI-powered software solution tailored to your specific business needs, as opposed to plugging in an off-the-shelf tool that only partially fits your workflow.

A RAG (Retrieval Augmented Generation) pipeline connects an AI language model to your own data, documents, databases, or knowledge bases. So it can answer questions accurately based on your content rather than general training data. If your AI needs to know things specific to your business, you likely need one.

A chatbot responds to questions in a conversation. An AI agent can reason through multi-step problems, use tools, make decisions, and take actions, like searching the web, writing to a database, or triggering another system. Agents are significantly more capable and complex to build.

Yes. API integration and system connection are core to how we work. We connect AI solutions to your existing CRM, ERP, databases, and third-party platforms so your AI works within your current stack, not alongside it.

Absolute. We offer hands-on AI tool training and team onboarding tailored to your team's skill level. Whether your team is new to AI entirely or needs to get more out of the tools they already have, we meet you where you are.
