What I'm looking for

I seek a role where I can build end-to-end web or mobile products, work with cloud and AI tooling, contribute to architecture decisions, and grow within a collaborative, multicultural engineering team.

I am a full-stack developer with extensive experience building web and mobile applications, skilled across frontend and backend stacks and comfortable working end-to-end from concept to maintenance.

I have delivered production apps using React, Vue, React Native, Node.js and Python, and I focus on performance optimization, clean architecture and automation to produce robust, maintainable systems.

Recently I designed and implemented an RAG-based web application using React, AWS Lambda (Python), OpenSearch, DynamoDB and AWS Bedrock, and I developed a React Native IoT mobile app shipped to the App Store and Google Play.

I thrive in multicultural teams, continuously learn new technologies (currently exploring Flutter and AI-driven tools), and prioritize code quality, continuous delivery and user-centered experiences.
