Applications Architect — 30 Years Enterprise Experience
Titus "Tuz" Aguilar
From AS/400 (IBMi) in the banking halls of the 90s to Python scripts and AI-powered apps today — I architect systems that last, and build tools that matter.

The Journey
1990s–2010s

Enterprise Architecture
Designing Data Warehouse and Analytics for middleware, and modernization strategies across large financial institutions.
2020s–Now
Linux & Python
Shell scripting, automation, data pipelines, and server-side Python work alongside legacy IBMi estates.
