What I'm looking for

I want to help teams embed practical LLM capabilities into real products—RAG, chatbots, and real-time voice AI—while keeping reliability, cost control, and prompt-injection awareness. I value clean APIs, strong UX, and measurable outcomes.

I’m an AI-Integrated Full Stack Developer and LLM Application Specialist with 15+ years building scalable web applications and 3+ years integrating AI/LLMs into production. I bridge classical web engineering with modern LLM integrations to ship practical, measurable AI value.

In production, I’ve built AI sales-training simulators and conversational experiences by integrating OpenAI GPT-4o, Gemini, Deepgram (ASR), and Amazon Polly (TTS). I design end-to-end solutions—RAG pipelines, real-time streaming, and voice-interaction systems—that help teams move from prototypes to reliable products.

I specialize in RAG & knowledge bases so my AI answers come from your own data, not just training sets. I also build responsible LLM features with human oversight, cost control, and prompt-injection awareness front-of-mind.

Most recently, I led RolPlay at TrueLogic, integrating GPT-4o/Gemini/Deepgram to power scenario-based simulations and building a real-time voice interaction pipeline with WebRTC and LLM response streaming. I’m now excited to help companies embed practical AI into their products, with clean API layers, fast iteration, and strong UX/UI awareness.
