What I Build

Full-spectrum web development, from simple marketing sites to complex e-commerce platforms.

Custom Website Development

Hand-coded or CMS-based websites using WordPress, custom PHP, React, or Next.js. Every site is built mobile-first with performance in mind.

Shopify Store Development

Custom Shopify themes, Liquid template development, app integrations, checkout customization, and complex product configurations.

WooCommerce & E-commerce

End-to-end WooCommerce stores with custom payment gateways, product builders, subscription models, and inventory management.

Landing Pages & Funnels

High-converting landing pages and sales funnels built with Elementor, custom HTML, or React. A/B test-ready with analytics.

Website Redesigns & Migrations

Modernize your existing site or migrate between platforms without losing SEO equity.

Speed & Core Web Vitals

Performance audits and optimization. Image compression, lazy loading, caching strategies for sub-2-second load times.

Responsive & Mobile-First

Every project is built to look and perform flawlessly across all devices, from 320px to 4K.

API Development & Integration

Custom REST APIs, third-party integrations, webhooks, and data synchronization.

My Process

Discovery & Planning

We start with a deep dive into your business goals, target audience, and technical requirements. Full project scope before any code.

Design & Prototyping

Wireframes and visual mockups. I design the UX/UI with conversion and usability in mind, iterating on your feedback.

Development & Testing

Clean, modular code with best practices. Every feature tested across browsers and devices. Staging previews throughout.

Launch & Optimization

Final QA, then go live. DNS, SSL, caching, CDN, performance optimization. Analytics configured from day one.

Ongoing Support

Post-launch maintenance, security updates, performance monitoring, and feature additions as your business evolves.
