AI Application Development
Practical Machine Learning for Real Products
Why AI Application Development?
The Strategic Advantage
The gap between AI hype and what founders actually need is massive. You probably don't need to train a 100-billion parameter foundation model from scratch. You likely need a classification endpoint that holds up in production, intelligent data extraction, or a well-tuned RAG (Retrieval-Augmented Generation) pipeline.
I focus on practical AI. Whether it's integrating the OpenAI API to summarize complex reports, or training a custom scikit-learn model for a specific classification task, I build AI features that ship to production and actually drive revenue.
I've built and deployed a Fake News Detection System achieving 94% accuracy using TF-IDF and LSTM, wrapped in a FastAPI endpoint. That's real AI in production, not just a ChatGPT wrapper.
✓Key Benefits
- Custom NLP Models: Text classification, sentiment analysis, and intelligent routing.
- LLM Integration: Securely integrate GPT-4 or Claude with your proprietary database (RAG).
- Predictive Analytics: Turn your existing data into actionable business forecasts.
- Production Serving: ML models deployed efficiently via FastAPI and Docker.
- Cost Optimization: Knowing when to use a cheap open-source model vs an expensive API.

LLM APIs vs Training Custom Models
Technical Comparison
| Criteria | OpenAI/Claude API | Custom Model Training |
|---|---|---|
| Time to Market | Days/Weeks | Months/Years |
| Cost | Low (Pay per token) | Extremely High (GPU Compute) |
| Use Case | Text, Logic, Chat | Highly proprietary data patterns |
| Maintenance | Managed by Provider | Requires MLOps team |
Frequently Asked Questions
Common Inquiries
Yes, I integrate OpenAI's GPT-4 API (along with Claude or Gemini) into applications, typically using a RAG architecture so the AI can answer questions based on your specific company data.
If we are fine-tuning an existing model or using traditional ML (like Random Forests), it can take a few weeks. Training deep neural networks from scratch takes significantly longer.
For custom ML, you need clean, labeled data. If you don't have data, we usually start with an LLM API approach, or build the application to start collecting the necessary data first.
Integrating an existing API (like OpenAI) is very affordable—features start around $1,500. Building custom data pipelines and training bespoke models is more expensive, starting around $4,000.
For custom models, I wrap them in FastAPI and deploy them via Docker to AWS EC2 or DigitalOcean Droplets, ensuring they scale properly under load.
