Hi, I'm John Beluca — a Senior Solutions Architect shipping AI systems into production.

12+ years architecting cloud and software for 40+ clients. The last year focused on agentic AI, RAG pipelines, and multi-provider LLM integrations — embedded into real client products, not demos.

I'm a Solutions Architect with 12+ years building cloud and software systems for 40+ clients across manufacturing, SaaS, healthcare, agribusiness, retail, and engineering.

Over the last year I've focused on architecting and shipping AI/LLM-powered solutions into production — agentic systems with tool-calling, RAG pipelines on vector databases, multi-provider integrations across OpenAI, Anthropic, and Gemini.

I work at the intersection of business strategy and technical execution — sitting with founders and C-levels during discovery, then leading engineering teams through delivery and long-term operations.
