๐ฑ Mobile App Development (Flutter | iOS | Android)
Most mobile apps fail not because of UI โ but because of weak backend logic and poor system design. That's where my background becomes a strength.
I build Flutter, native iOS (Swift/SwiftUI), and Android (Kotlin/Java) apps that integrate with secure backends, REST APIs, and admin dashboards โ making your app the execution layer of a complete product, not just a standalone front end.

โ Business & internal apps with real workflows
โ Customer-facing production-ready apps
โ Firebase, Supabase, Node.js & Laravel backend integration
โ Push notifications, payments (Stripe, in-app purchases), maps & more
โ App Store & Google Play submission & optimization
โ Clean, scalable architecture built for long-term growth
๐ Web Development & Design
I'm also a full-stack web developer with deep expertise across modern web technologies โ delivering fast, secure, and visually compelling websites that rank on Google and convert visitors into customers.
My web stack includes:
WordPress โ custom themes, plugins, WooCommerce, e-commerce migrations
Laravel & PHP โ robust backend systems, custom web applications
React.js โ dynamic, component-driven frontend development
Webflow โ pixel-perfect no-code/low-code builds with complex interactions
HTML, CSS, JavaScript โ clean, standards-compliant code across every project

โ E-commerce stores (WooCommerce, Shopify migration)
โ SEO-optimized, mobile-responsive layouts
โ Speed optimization & Core Web Vitals improvement
โ Complex Webflow features & custom interactions

๐ฏ What You Get Working With Me
๐ฆ Clean, maintainable code โ easy to hand off or scale
๐๏ธ Scalable architecture that grows with your business
๐ Clear milestones, realistic timelines, zero surprises
๐ SEO best practices built into every web project
