What I'm looking for

I'm looking to build and maintain cross-platform mobile and modern web applications, collaborating with product, design, and engineering teams while growing through hands-on feature delivery.

I've built cross-platform mobile applications at Datax using React Native, JavaScript, and TypeScript, delivering features, bug fixes, performance improvements, testing, deployment, and maintenance.

At Datax, I also programmed embedded devices for smart refrigerators, including weight monitoring, inventory control, sensor integration, automation systems, and communication between devices and systems.

As a freelance developer, I've delivered a production-ready MVP with React, Next.js, TypeScript, and REST APIs. I build responsive interfaces and reusable UI components, resolve production issues, and work directly with clients to refine requirements and improve user workflows.

I'm comfortable collaborating across product, design, and engineering teams in Agile environments, using Git throughout the software development lifecycle.
