What I'm looking for

I seek backend or cloud-focused roles where I can build scalable, AI-enabled data systems, work with AWS/Azure, and drive measurable product impact in collaborative teams.

I see backend engineering as a form of translation—turning complex needs into simple, reliable systems. My latest work translated the challenge of financial analysis into an intuitive semantic search experience using GPT-5. I’m always learning the next 'language'—technical or otherwise—that helps me solve difficult engineering problems with clarity and purpose.
