I'm a Shopify Developer with hands-on experience building, customizing, and maintaining production Shopify stores. I specialize in Shopify Liquid, Online Store 2.0, custom theme development, app integrations, and performance optimization.

I help businesses improve their online stores by developing custom features, fixing complex bugs, optimizing storefront performance, and creating seamless customer experiences. My experience includes:

Petroleum terminal operations professional with 7+ years of hands-on bulk liquid freight experience, transitioning into US freight dispatching as a Virtual Assistant. Currently coordinating 180+ tank trucks daily and 100M+ liters of petroleum movement monthly at one of the Philippines' largest independent import terminals.
I bring the physical operational understanding of how freight moves, is measured, documented, and transferred — the foundation most dispatch VAs never develop. I have completed structured self-study in US freight dispatch: DAT load board operations, rate negotiation, the 7-step dispatch workflow, BOL/POD processing, TMS platforms (McLeod, Rose Rocket, Turvo), ELD monitoring (Samsara, Motive), and professional US broker/driver communication.
What I offer: zero-error documentation discipline, calm multi-task coordination under time pressure, and real operational experience directing drivers, clients, and contractors simultaneously.

Hi! I'm Mara, a Shopify Developer with 8+ years of hands-on experience building and customizing Shopify stores that look polished, load fast, and convert.
I specialize in Liquid theme development, front-end customization, and performance optimization — helping store owners get clean, pixel-perfect results without the back-and-forth. I've worked with clients in Australia, the US, and the Philippines across industries ranging from fashion to home goods.
Beyond Shopify, I've handled multi-channel product listings on Amazon FBM, Faire, Walmart, and TikTok Shop — so I understand the bigger e-commerce picture, not just the storefront.
What I can help you with:

- Shopify Theme Development & Customization (Liquid, HTML5, CSS3, JS)
- Page Speed & Core Web Vitals Optimization
- App Integration & Custom Feature Development
- Responsive, Mobile-First Design
- Metafields, Sections, and Shopify 2.0 Features
- Multi-platform Product Listing Management

I communicate clearly, meet deadlines, and treat your store like it's my own. If you're looking for a reliable Shopify developer for a one-time project or ongoing support, let's talk.

I build Shopify stores that load fast, convert well, and look custom. My recent project, LuxeWear, is a fully custom theme built from scratch using Liquid, HTML, CSS, and JavaScript. It hit a 95 Performance and 100 SEO score on Lighthouse, with an FCP of 0.6s and LCP of 1.2s. That kind of output does not happen by accident.
Beyond theme development, I understand how e-commerce actually works. I have spent time on both sides of the operation: building store infrastructure and running live selling operations at Unicharm Philippines, where I grew session audiences to 500+ viewers and contributed to a 30% lift in live sales. I know what it takes to drive conversions, not just build pages.
I am currently finishing my BS Computer Science degree (Software Engineering) at Far Eastern University while working full-time, so yes, I can handle pressure and deadlines.
If you need a Shopify developer who brings both technical depth and real e-commerce experience, let's talk.
