Core expertise
A little background on who I am and how I work.
I'm a passionate web and app developer specializing in building modern, responsive applications. With full-stack expertise and a focus on cross-platform compatibility, I help turn ideas into polished, production-ready products.
Whether it's a high-performance web app, a native mobile experience, or a robust backend API, I handle the complete development cycle — from architecture and database design to UI and deployment.
Services and disciplines I specialize in.
Responsive, performant websites and web apps using modern frameworks like React, Vue.js, and Next.js — built to scale and optimized for every screen.
Native and cross-platform apps for iOS and Android. From Swift and SwiftUI to Flutter, I ship polished mobile experiences with tight platform integration.
Complete development cycles from database design and REST/GraphQL APIs to frontend delivery — Node.js, Python, PostgreSQL, MongoDB, and cloud infra on AWS.
Interfaces centered on usability and accessibility. Clean design systems, intuitive navigation, and thoughtful interactions that make products feel great to use.
Tools and technologies I work with day to day.
