I've built logistics, e-commerce, authentication, ticketing, medical licensing, and coffee-machine backend products for Endava, Grid Dynamics, Eycrowd, CodeFinesse, and WebUpDevelopment. My work spans React, Node.js, Express.js, PostgreSQL, MongoDB, PHP Laravel, AngularJS, and React Native.

I've led teams of six and three while delivering checkout flows, loyalty systems, multi-factor authentication, image-generation learning apps, and event platforms. I bring 10 years of web development experience, with a practical focus on testing, security, and shipping applications from in-house to outsourced environments.
