Sergio Herrera

About Me

Shopify Developer & Educator

I'm Sergio, a Shopify developer based in Lima, Peru, working remotely with US-based e-commerce brands.

With 5+ years of experience in fast-paced startup environments, I specialize in building and optimizing Shopify stores using Liquid, JavaScript, and modern frameworks like Vue.js. My background blends technical expertise with business understanding—I studied Business Engineering at UPC before diving into full-stack development at Codeable.

I'm currently Lead E-commerce Developer at Plant Therapy, where I'm the sole technical owner of a high-traffic Shopify platform generating $1M+ in monthly revenue with 335k+ sessions and a 4.43% conversion rate. I work directly with C-level executives to provide strategic technical consulting and build custom solutions including advanced discount systems, checkout validations, and Shopify Functions.

I also run MTB Labs, my development agency focused on helping US DTC brands scale their Shopify stores.

When I'm not coding, you'll probably find me with Mía, my Saint Bernard who serves as Chief Mascot Officer at MTB Labs.
