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.

B2B SaaS / Consulting Operations

Full Engage — Operating System for Multi-Client Consultants

A multi-tenant SaaS that gives fractional executives and advisory firms one operational backbone for every client engagement — tasks, meetings, notes, time tracking, and an AI co-pilot, all isolated per client workspace.

Why your RAG retrieval is bad (and it's probably not the embeddings)

After shipping half a dozen RAG systems into production, I keep seeing the same retrieval failures. The model is rarely the problem — chunking and metadata are.
Agents Mar 2026 · 6 min

Tool-calling is just a remote procedure call with anxiety

How I think about designing tools for agents — naming, scoping, idempotency, and why your agent keeps looping.

A boring AWS architecture for a not-boring AI product

The reference architecture I've used to ship three production AI systems. ECS, Lambda, SQS — nothing fancy, and that's the point.

§ III. Background

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. I'm open to contracts, just contact me on my email
