Everything you need to feature Celestino Salim at your event.
Celestino Salim is a Senior Software Engineer based in Miami Beach who explores unfamiliar problems and ships production AI systems. His focus areas include RAG pipelines, LLM evaluation, agentic systems, voice agents, and cost optimization. He combines 8+ years of software engineering with full-stack product experience to make AI reliable and profitable.
Celestino Salim is a Senior Software Engineer based in Miami Beach who walks into unfamiliar territory and ships production AI systems. He combines 8+ years of software engineering, including shipping at massive scale at Eventbrite, with deep expertise in RAG pipelines, LLM evaluation, voice interfaces, and production AI architecture. His approach: explore the problem, learn what's needed, build it, and get it to production. He has re-architected retrieval systems to cut costs by 99% (making the business model viable) and introduced reliability standards that increased user trust and impressions by 482%. Previously, he shipped at 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 shares what he learns at Celestino.ai.
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 that cut API costs by 99% at Eventbrite. 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.
Propose a talkSenior Software Engineer with 8+ years at Eventbrite, FlowWest, and ESLWorks. Built Arepa.AI and celestino.ai. Speaker topics grounded in production experience, not theory.
