Everything you need to feature Celestino Salim at your event.
Senior Software Engineer specializing in agentic AI systems and product engineering: builds agentic AI that ships to production, reliable and cost-viable. Based in Miami Beach.
Celestino Salim is a Senior Software Engineer specializing in agentic AI systems and product engineering, based in Miami Beach. He spent 8 years shipping production software at scale, including Eventbrite (300M+ tickets), and the last year building Arepa.AI end to end: multi-agent orchestration, RAG pipelines, voice interfaces, and the evaluation harnesses that keep them honest. He treats AI implementation as a systems engineering challenge: reliable and profitable, not just impressive. His focus is unit economics and reliability: retrieval architectures designed around cost, evaluation harnesses instead of vibe checks, and the runbooks that keep AI systems shippable. He publishes the how: architecture decisions, tradeoffs, and postmortems from real production work. Previously, he learned to ship at massive scale as a Senior Engineer at Eventbrite and led infrastructure teams at FlowWest and ESLWorks. Today, he builds Arepa.AI for Spanish-speaking SMBs and writes at celestinosalim.com.
How to move from demo to production. Common failure modes, evaluation frameworks, and the infrastructure gap most teams ignore. This session covers the unglamorous but critical work of making AI systems reliable enough to trust with real users and real money.
Why your AI costs 100x more than it should. Unit economics frameworks, caching strategies, and the model tiering approach I used at Eventbrite: architecture decisions published, not implied. Walk away with a playbook to audit your own AI spend and fix it.
Building retrieval systems that actually work. Chunking strategies, hybrid search, reranking, and why your RAG pipeline is bleeding money. A practical session grounded in production lessons, not academic benchmarks.
From model to product. The gap between a working demo and a profitable business, and the engineering decisions that close it. Covers pricing, reliability thresholds, and the metrics that matter when shipping AI to paying customers.
No public talks yet. Let's build something great together. I'm selective about topics and audiences because I want every talk to deliver real, actionable value.
