Carlos Aguilar
Principal Engineer & Architect
I don't just build apps; I engineer stability.
Before founding Tecmanic, I spent 5 years at Capital One as a Staff Engineer and Payments Architect. I led initiatives that generated over $10M in annual revenue and saved the company millions by optimizing high-volume API infrastructure.
My background isn't typical agency work. I've handled critical data migrations for the Library of Congress, scaled consumer apps to 50M+ downloads, and engineered 99.9% stability for high-growth startups. I bring that same level of rigor to every client I work with.
