Chi sono
I am a senior e-commerce backend and infrastructure engineer specializing in Shopify Plus and WooCommerce performance, checkout extensibility, and payment gateway architecture.
Standard web designers build stores; I keep high-volume stores from crashing when traffic spikes. My focus is eliminating mobile checkout friction, repairing broken wallet APIs (Apple Pay, BNPL), fixing server-side data tracking leaks, and securing international tax pipelines.
If your store is leaking revenue due to technical bugs or gateway timeouts, let's get it fixed without disrupting your live traffic.
