What I'm looking for

I seek roles where I can design scalable architectures, lead frontend modernization, improve CI/CD and testing, mentor teams, and work in collaborative Agile environments.

I am a Full-Stack Software Engineer with over four years building scalable, high-performance web applications across cloud and enterprise environments. I drive frontend architecture decisions, modernize legacy systems, and implement automation and testing practices that reduce operational overhead and increase reliability.

I have delivered production systems using TypeScript, Angular, .NET, Node.js, and cloud technologies, and I mentor teammates while promoting engineering best practices. My work emphasizes accessibility, modularity (microservices/microfrontends), CI/CD, and observability to ensure maintainable, performant products.
