Full-Stack Developer
I turn ideas into full-stack apps - robust on the backend, seamless on the frontend, and powered by the cloud.

What I do
End-to-end product work — from the data model and API through to the interface people actually touch.
Next.js, React, Express, Node.js, PHP and Tailwind CSS - fast, accessible, production-ready web applications.
React Native, Flutter and Dart. Cross-platform apps that feel native on both iOS and Android.
Node.js, Express, Python Django and Java Spring Boot. Well-documented REST APIs and solid authentication.
MongoDB, MySQL and PostgreSQL. Schema design, indexing and migrations for structured and unstructured data.
Cross-platform desktop applications built with Electron and .NET for Windows, macOS, and Linux.
Python ML pipelines - predictive models, data cleaning and evaluation you can actually deploy.
