Hi, I'm Shawn
Anston.

A bit about me

I'm a Mainframe Systems Analyst with 9+ years of experience bridging legacy infrastructure and modern cloud architecture. I specialize in COBOL, DB2, CICS, and IMS, with proven success delivering cost-saving Kaizen initiatives and leading cross-functional teams across onsite and offshore models.

From automating CA7 job monitoring with REXX to migrating monolithic apps to AWS microservices, I'm driven by the challenge of making complex systems simpler, faster, and future-proof. AWS Certified Cloud Practitioner. Based in Carrollton, Texas.

Outside of work, I'm an avid gamer — RPGs and strategy games are my go-to, but I'll pick up just about anything. I also love football, though it's been a while since I've been on the field myself. Reading is another big passion of mine; I'll dive into pretty much any topic. Whether the conversation turns to video games, quantum mechanics, or anime, I'm always up for it — the one exception might be live sports, since I don't follow them too closely.
