About me
Where code becomes product
I'm a software engineer focused on backend, DevOps and cloud infrastructure, with a solid background in telecommunications. I work at the intersection of code, networks and operations — where a well-designed system turns into a reliable product for real users.
Over the last few years I've shipped APIs and pipelines, designed and deployed networks for retail and industry, and worked across cloud and on-prem infrastructure. I've also led technical teams. I'm drawn to problems that need both good architecture and operational judgement.
