About this gig
WELCOME TO MY GIG
Need custom BigCommerce Stencil edits, dynamic Handlebars components, or Checkout API logic? Standard themes limit your experience. I build clean, high-performance customizations tailored to your exact workflow.
From front-end UI components to Checkout SDK scripts and REST/GraphQL APIs, I write maintainable code following BigCommerce standards.
Technical Services Offered:
Stencil & Handlebars Development:
- Custom Handlebars.js components, widgets, & dynamic templates
- Stencil CLI theme edits, page layout customization, & CSS/JS tweaks
- Responsive mobile optimization & front-end bug fixes
APIs & Custom Checkout:
- BigCommerce Checkout SDK modifications & custom checkout fields
- Storefront, Management, & GraphQL API integrations
- Third-party app & custom serverless webhook connections
Why Choose Me?
- Clean Code: Standard Stencil CLI compliance for smooth theme updates
- Tested Delivery: Thoroughly tested on live & preview store environments
- Performance Focused: Fast load speeds with zero layout breakage
NOTE: Custom development requires technical scoping. Please contact me before ordering with your spec details. Let's build!

FAQ
Can you work directly on my live BigCommerce store without downtime?
Yes, I develop and test code using the BigCommerce Stencil CLI locally or on a private preview/staging theme. Your live store stays 100% functional, and changes are applied to your live site only after you test and approve them.
Will custom Handlebars components break when I update my BigCommerce theme?
I write clean, modular code that follows official BigCommerce Stencil guidelines. While minor theme layout updates stay safe, major theme replacement requires copying over custom component files—I provide clear documentation
Can you customize the native BigCommerce One-Page Checkout using APIs?
Yes! I use the BigCommerce Checkout SDK and GraphQL/REST APIs to add custom checkout fields, modified shipping/payment steps, and automated validation rules without breaking native security or PCI compliance.
