Career Evolution
Each chapter of my career unlocked new skills and harder challenges.
- Origin Story
COBOL & Mainframe Systems
Started in legacy systems, mastering COBOL, JCL, DB2, and mainframe architecture across enterprise-scale codebases. Built a foundation in discipline, precision, and large-system thinking.
- Evolution
.NET Mobile Development
Moved into the .NET ecosystem, building cross-platform mobile applications with Xamarin Forms and .NET MAUI. Shipped production apps for Polaris, AXA, and personal projects using clean architecture and MVVM.
- New Frontier
React & Web Development
Expanded into modern web, building responsive interfaces with React, Next.js, and Tailwind CSS. Applied component-driven architecture and server-side rendering to deliver fast, accessible experiences.
- Power Up
DevOps & Automation
Added DevOps to the toolkit, designing Azure CI/CD pipelines, automating build and deployment workflows, and streamlining release processes across mobile and web platforms.
- Side Quest
Unity Game Development
Exploring game development with Unity, prototyping 2D games, learning physics systems, and applying C# scripting skills in a creative context.
The Gamer Advantage
When not coding, I'm exploring open worlds, tackling RPG raids, and building Unity prototypes. Gaming reinforces the same skills I use daily: persistence, strategic thinking, and attention to craft.
