Production AI.
AI systems, voice agents, and RAG pipelines — from first commit to production.
Engineering leader evaluating a candidate. Founder with a problem to solve. Builder who wants to go deeper. You're in the right place.

Explored. Built. Shipped.
Every project below started as unfamiliar territory. I dug into the problem, learned what was needed, and shipped a real system.

8+ years of shipping across unfamiliar problems — from startup MVPs to Tier-1 growth engineering.
Engineering & Consulting
You bring the problem. I'll dig into it with you, build the first version, and get it to production. No prior AI experience required on your end.
- From Idea to Product
- AI Strategy & Architecture
- Production Systems
Courses & Deep Dives
Whether you've never touched AI or you ship daily, there are structured paths from fundamentals to production systems. Built from real projects, not theory.
- Beginner-Friendly Courses
- Production Patterns
- Code Templates
How I work.
Same approach whether I'm on your team or building from scratch.
- 01
Understand the Problem
I start by understanding what you're trying to solve, not what tools to use. Simple prompts first, agentic systems only when the problem demands it. Your problem shapes the solution, not the other way around.

About Me
I Figure Things Out. Then I Ship Them.
I am Celestino Salim, a Senior Software Engineer based in Miami Beach.
I don't wait to be an expert before I start building. New framework, unfamiliar industry, problem I've never seen. I dig in, learn what's needed, and ship something real. That's how I worked with the Growth team at Eventbrite to cut retrieval costs by 99% across thousands of daily queries and grew organic impressions by 482%. Not because I'd done it before, but because I committed to figuring it out.
