About Me

I am a Principal AI Engineer who specializes in designing and delivering high-impact AI systems that solve real business problems at scale. My work spans speech intelligence, LLM-driven automation, RAG pipelines, and document processing—combining deep technical knowledge with a strong focus on reliability, performance, and real-world value.

Over the years, I have architected and shipped multiple production AI platforms including real-time voice agents, multilingual transcription and QA systems, and multi-tenant document intelligence suites for enterprise customers. I enjoy taking complex, research-grade ideas and turning them into clean, maintainable, and high-performance products that teams can trust.

My core strengths include building modular and scalable microservice architectures, optimizing GPU workloads, fine-tuning LLMs, and creating robust observability layers. Beyond engineering, I mentor teams, establish engineering standards, and collaborate closely with business leaders to ensure AI solutions align with KPIs and operational goals.
