js. js APIs into Shopify-based systems.

About

I’m a full-stack developer with strong experience in JavaScript, HTML, CSS, and backend development using Node.js. While I haven’t directly built full Shopify stores, I’ve worked with developers to integrate custom Node.js APIs into Shopify-based systems.

Through this, I gained practical understanding of how Shopify apps interact with external services, handling API communication, debugging issues, and making sure everything runs smoothly between the store and backend systems.

I’m comfortable jumping into existing codebases, troubleshooting problems, and delivering clean solutions without overcomplicating things. I also focus on performance and keeping the user experience smooth when adding or fixing features.

I work well with teams, communicate clearly, and make sure tasks are done on time. I’m also quick to learn, so getting deeper into Shopify (Liquid and theme customization) is something I can ramp up on fast.
