About me

Information Technology Management Engineer with 5 years building web systems for financial, government, educational, and enterprise sectors.

My differentiator is translating business needs into functional architectures — from mapping the flow with the owner to deploying to production and training the end team. I leverage AI (Claude, ChatGPT) in my daily workflow to deliver faster without sacrificing quality.

Currently leading the development of a Mexican financial company's sales system (691 credit requests processed in 5 months) while maintaining active freelance projects.
