What I'm looking for

I seek a role where I can build scalable, AI-integrated frontend systems within cross-functional teams, emphasizing reliability, performance, and growth.

I am a software engineer with 7+ years building large-scale, responsive multi-platform applications, focused recently on scalable frontend systems using JavaScript, React Native, and ReactJs.

At my most recent role I contributed to production systems that integrated AI capabilities — automated code review, effort estimation, test-case generation, and document search using large language models — prioritizing reliability and practical deployment constraints.

I have full-stack experience across frontend and backend domains, having designed reusable components, backend microservices, and GraphQL APIs for banking and enterprise systems, with attention to performance and maintainability.

I work well in cross-functional teams, applying test-driven development and agile workflows to translate complex business problems into robust technical solutions that balance usability and system constraints.
