ABOUT ADRIAN MACAL
I’m not a consultant, and I don’t want to be another one - I build and deliver real, working systems. From infrastructure and DevOps to data modeling and BI, I work end-to-end across the stack, driven by curiosity and a bias for action.With 20+ years in Data Engineering and Software Development, I focus on code that performs in production - not in slides. Whether wrangling pipelines, optimizing query plans, or writing low-level Rust for the challenge, I make things happen. I’ve built and maintained systems that process dozens of terabytes daily - reliable, observable, and designed to scale under pressure.If you need someone who builds the backbone of your data systems—not just talks about it—let’s talk.If you made it all the way down here, drop “i13c” in your message. It’s my way of telling who reads before writing.
