Let's talk AI

AI Architect with 15+ years in software engineering. Language-agnostic, goal-focused. I design intelligent systems, lead engineering teams, and bridge the gap between AI research and production. From conversation intelligence to agent architectures — I turn complex AI into real-world products.

Engineering with purpose

I'm an AI Architect. Language-agnostic and goal-focused — I pick the right tool for the job, not the other way around. Over the years I've designed and shipped AI-powered platforms, LLM integrations, and production ML pipelines for startups and enterprises alike.


I care about outcomes over technology choices, clean system design, and infrastructure that scales. When I'm not building AI systems, I maintain open source projects and explore the frontiers of generative AI, agent architectures, and cloud-native ML tooling.

Focus areas

Where I bring the most value.

AI Agent Architecture
Designing and building production-grade AI agents — from conversation flows and tool orchestration to reliability, cost optimization, and human-in-the-loop patterns.
Conversation Intelligence
Building systems that understand, analyze, and act on conversations at scale. Real-time transcription, intent detection, sentiment analysis, and actionable insights from voice and text.
LLM Integration
Integrating large language models into existing products and workflows. RAG pipelines, prompt engineering, fine-tuning strategies, and MCP server development for tool connectivity.
