I will build custom ecommerce features or setup third party api integration
Thorsten Weib
About this gig
STOP LETTING TEMPLATE LIMITATIONS AND BROKEN API HOOKS BOTTLENECK YOUR E-COMMERCE SCALE.
Standard themes and generic plugins only take your business so far. When your store requires custom checkout rules, multi-platform inventory syncing, or advanced third-party API tracking layers, out-of-the-box templates fall apart and drag down server load times.
I build highly optimized, secure custom features and API integrations for Shopify, WooCommerce, and custom web applications. I bridge the gaps between your storefront, warehouse management systems, CRM platforms, and payment routers with clean, lightweight backend code.
What I engineer for your platform:
- Secure Third-Party API Integrations (Stripe, alternative gateways, ERPs)
- Custom automated data loops via automated Webhook scripts
- Tailored checkout variations and multi-attribute product filters
- Server-side tracking script hooks and data parity layers
- Custom app extension development for specific store management actions
Unlock advanced functionality. Contact me for a technical consultation before ordering!

I’m Thorsten Weiß. A beautiful store is useless if its code is slow or its backend integrations fail under load. Based in Germany, I specialize in full-stack Shopify and WooCommerce engineering. From seamless platform migrations with zero downtime to building custom features and deep ERP/API integrations, I focus on scalable architecture. I build bulletproof digital storefronts optimized for conversion and speed.

FAQ
Can you integrate alternative or high-risk payment gateways via custom API?
Yes. I build secure API request hooks connecting alternative merchant payment providers, specialized localized checkouts, or alternative payment networks directly to your native platform's checkout array.
Do you write custom automation scripts to bridge Shopify or WooCommerce with external CRMs?
Absolutely. I write explicit, lightweight webhook handlers and data loops that instantly mirror incoming customer profiles, specific sales matrices, and order details into external tracking apps or platforms.
Will adding custom feature scripts slow down my storefront's page loading speeds?
Never. I prioritize minified, asynchronous asset execution and clean backend query patterns. Every script injection or API endpoint layout is performance-tested to maintain light execution weights.
Can you resolve existing data mismatches between multiple connected store systems?
Yes. I diagnose broken API pipelines, mismatched payload properties, and authorization failures between your store inventory layers, shipping providers, and fulfillment dashboards.
