I build SaaS platforms that handle real users, real payments, and real AI features, not demos.
I'm a Full-Stack Developer with 6+ years of experience shipping production web and mobile applications, specializing in SaaS platforms, AI-powered tools, and Stripe integrated systems. My core stack is React/Next.js, Node.js, and Python, backed by PostgreSQL, MongoDB, or Supabase depending on the project.
What I've shipped recently:
Multi-tenant SaaS platforms with subscription billing and AI integrations (Claude/OpenAI)
E-commerce and marketplace platforms with Stripe payments
React Native mobile apps published to both App Store and Play Store
Automation systems connecting CRMs, payment processors, and third-party APIs
I work with a small team senior developers, a QA engineer, and a project manager, so delivery stays structured even on larger builds.
If you need someone who can take a product from architecture to production and actually own the outcome, let's talk about what you're building.

Are you tired of slow, broken, or insecure WordPress websites that cost you sales?
As automated tools and generic templates flood the market, business owners are realizing that "quick fixes" often break under pressure. You don't just need code; you need a human expert providing strategy, accountability, and deep technical architecture across multiple platforms.
With over 8+ years of professional experience as a Full-Stack Web & E-commerce Developer, my focus is on solving complex performance, e-commerce, and security problems that automated tools simply cannot handle. Whether you are running on WordPress or Shopify, I engineer solutions that scale.
Here is how I can help your business:
🛍️ Shopify & E-commerce: Custom Liquid development, theme customization, and Shopify store setups optimized for high conversion rates.
🚀 WordPress Custom Architecture: I build complex plugins and custom themes from scratch—handling the deep PHP/JS logic that basic tools fail at.
🛒 WooCommerce Mastery: From complex product variations to custom checkout flows, I build stores that actually scale and sell.
🛡️ Bulletproof Security & Debugging: Expert in untangling messy code, malware removal, and total site architecture hardening.
📈 Performance & Headless: I optimize sites to score 90+ on Google Lighthouse and build Headless setups (React/Next.js) for ultimate speed.
Why work with me?
I am fundamentally a problem-solver. I've successfully completed 60+ projects on Upwork with a 5.0 rating because I prioritize communication, dead-on-time delivery, and clean code that won't break on the next update.
Core Tech Stack:
Platforms: WordPress, WooCommerce, Shopify
Frontend: HTML5, CSS3, JavaScript, Tailwind, Shopify Liquid
Backend & Logic: PHP (Advanced), MySQL, REST APIs, Custom Plugin Logic
