Online Stores That Sell While You Sleep
E-commerce development services for businesses ready to sell online. I build WooCommerce and custom e-commerce platforms with product catalogs, payment processing, order management, and conversion-optimized checkout — based in the Philippines.
Most ecommerce stores leak revenue at every step of the funnel.
Slow load times, clunky checkouts, mismatched payment gateways, and inventory that never matches what is actually on the shelf — these are not cosmetic problems. They are conversion killers that cost real money every single day your store is live.
Template stores look fine at launch but fall apart under real traffic: they cannot handle product variants, shipping rules, or tax logic for multiple regions. Building a store that actually scales requires intentional architecture — not drag-and-drop shortcuts.
Ecommerce architecture built to convert and scale.
I design and develop ecommerce stores that are fast, secure, and optimized from product page to payment confirmation. Based in Davao City, Philippines, I deliver remotely with clear async communication that fits US, AU, and EU business hours.
- Average 28% increase in checkout completion rate post-optimization
- Sub-2-second load times on all builds with proper image and asset optimization
- Supports multiple payment gateways, currencies, and regional tax rules
- Inventory and fulfillment integrations with major 3PL and warehouse platforms
- Full source code ownership — no vendor lock-in on your storefront

From Discovery to Live Store
Store Discovery
We map your product catalog, customer journey, payment needs, and shipping rules. This session defines the full scope before any development begins.
Platform and Architecture Decision
I recommend the right platform — WooCommerce, Shopify, or custom — based on your catalog size, budget, and growth plans. You get a clear rationale before we commit.
Build and Configure
Storefront development, product setup, payment gateway integration, and all backend configuration in parallel. A staging environment is available for your review throughout.
QA and Checkout Testing
End-to-end checkout tested across devices and payment scenarios. Every edge case — failed cards, out-of-stock items, address validation — is verified before launch.
Launch and Handoff
DNS cutover, SSL verification, and go-live checklist completed together. Documentation and admin training delivered so your team can manage the store independently from day one.
What Makes These Stores Actually Perform
Conversion-First Design
Every layout decision — product pages, add-to-cart flows, checkout steps — is made with conversion rate in mind. Trust signals, urgency cues, and frictionless UX are standard, not optional extras.
Speed Optimized Out of the Box
Image compression, lazy loading, CDN configuration, and minimal plugin bloat are baked into every build. Fast stores rank better and convert better — this is non-negotiable.
Secure Payment Handling
All payment integrations follow PCI compliance best practices. No card data ever touches your server — tokenization and secure redirects are standard across every gateway.
Inventory That Stays Accurate
Real-time stock sync, webhook-based updates, and reserve-on-checkout logic prevent overselling even during flash sales or high-traffic spikes.
Async-First Delivery
Based in Davao City, Philippines (UTC+8). Projects run async-first with Loom walkthroughs, written updates, and GitHub access. US, AU, and EU clients get full visibility without timezone friction.
Documented and Self-Manageable
Every store ships with an admin guide your team can follow to add products, update pricing, run promotions, and troubleshoot common issues — no ongoing developer dependency for day-to-day operations.
Ecommerce Stores Delivered, Revenue Measured
"Johnbert rebuilt our WooCommerce store from scratch after our previous developer left us with an unmaintainable mess. The new store loads in under 1.5 seconds and our checkout completion rate went from 54% to 79%. That improvement translates to thousands of dollars per month in recovered revenue."
"We needed a Shopify build with custom wholesale pricing logic and a B2B portal — not something any standard theme handles well. JB scoped it clearly, delivered on schedule, and the checkout flow for our wholesale buyers is exactly what we needed. No hacks, clean code."
"We had persistent cart abandonment issues we could not diagnose. Johnbert audited the checkout, identified three friction points in the payment flow, and rebuilt those sections. Abandonment dropped by 33% in the first month. His documentation also meant our internal team could make future changes without calling him."
