About Me
Learn about my background, skills, and experience
Senior software engineer with 14 years of experience building ecommerce storefronts, backend systems, and databases. I specialize in Shopify Plus and headless Hydrogen builds for global brands, backed by deep PHP/Laravel, MySQL, and server experience. I have led migrations, multi-market pricing setups, B2B login and registration flows, and high-traffic gaming platforms from the ground up. Known for finding the root cause, comparing options with clear criteria, and writing it up so clients can decide.

How I Work
The habits behind the work
Troubleshooting
Capture evidence, find the root cause, do the safe big win first, verify, then prevent it from happening again.
Client work
Check the official docs for the exact API version, compare options against clear criteria, build a sandbox or demo, then write it up.
Habits
Write current vs expected behavior before coding, work around platform limits, check timing when a bug won't reproduce, and confirm business rules before changing logic.
