Raphael Mendes

I help businesses bridge the gap between complex AI capabilities and real-world operational efficiency.

With a background in Systems Engineering, I specialize in building hybrid architectures that combine the creative power of LLMs (OpenAI, Anthropic, DeepSeek) with deterministic, production-ready logic. I don't just 'prompt'—I engineer scalable systems that solve business bottlenecks.

What I bring to your project:

Custom AI Agents: Development of autonomous agents designed for specific workflows (Customer Support, Data Analysis, Content Generation).

LLM API Integration: Seamlessly connecting advanced AI models into your existing software ecosystem or CRM.

End-to-End Hybrid Systems: Building the full stack—from robust Python backends to functional, data-driven dashboards.

Process Automation: Transforming manual, repetitive tasks into intelligent, automated pipelines that save hundreds of hours.

My focus is on reliability and ROI. I build AI solutions that are predictable, secure, and easy for your team to use."
