What I'm looking for

I seek senior engineering roles where I can build scalable cloud-native systems, lead teams, and drive product impact in agile environments.

I am a Senior Full Stack Software Engineer with 7+ years designing and delivering scalable web applications and cloud-native solutions across startup and enterprise environments.

I build secure, high-performance systems using React, TypeScript, Java, Python and microservices architectures, and I’ve delivered features that improved efficiency, page load times, and customer retention.

At HubSpot I engineered distributed backend services processing 5M+ daily events, designed AWS infrastructure and CI/CD pipelines, and led a team of seven developers to raise delivery velocity and reliability.

Previously at ClickUp I delivered real-time collaborative features, improved test coverage and performance, and championed quality and agile practices to accelerate releases and reduce production incidents.
