About Me
Systems Thinking, Not Magic.
I am Celestino Salim, a Senior Software Engineer based in Miami Beach.
I bridge the gap between a cool demo and a profitable business. I re-architect retrieval pipelines to cut costs by 99% and build evaluation harnesses that prove reliability. If you're tired of "vibe checks", let's talk engineering.
