Web Development

Custom-built websites and applications that perform. From WordPress to Shopify to fully custom React apps, I build digital experiences that are fast, scalable, and designed to convert.

What I Build

Full-spectrum web development services, 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 like credit systems.

🛒

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 integration.

🔄

Website Redesigns & Migrations

Modernize your existing site or migrate between platforms (The7 to Elementor, WordPress to Shopify, etc.) without losing SEO equity.

Speed & Core Web Vitals

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

📱

Responsive & Mobile-First

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

🔌

API Development & Integration

Custom REST APIs, third-party integrations (CRMs, payment processors, shipping providers), webhooks, and data synchronization.

🔧

WordPress Plugins

Custom plugin development for specific business needs. Multi-step forms, package builders, pricing calculators, and admin dashboards.

My Process

A structured approach to every web development project, from initial brief to ongoing support.

01

Discovery & Planning

We start with a deep dive into your business goals, target audience, competitors, and technical requirements. I map out the full project scope, timeline, and deliverables before writing a single line of code.

02

Design & Prototyping

Wireframes and visual mockups come next. I design the user experience and interface with conversion and usability in mind, iterating based on your feedback until we nail the look and flow.

03

Development & Testing

This is where it gets real. Clean, modular code is written with best practices. Every feature is tested across browsers and devices. I keep you updated with staging previews throughout.

04

Launch & Optimization

After final QA, we go live. I handle DNS, SSL, caching, CDN setup, and performance optimization to ensure your site launches fast and secure. Analytics and tracking are configured from day one.

05

Ongoing Support & Maintenance

Post-launch, I provide ongoing maintenance, security updates, performance monitoring, and feature additions. Your site stays healthy and evolves with your business.
