Hi, I'm Umar 👋

This is my first personal website running on Cloudflare Workers.

I'm currently a software engineer at Ramp working on compute, CI/CD, networking & observability.

Highlights include:

Managing all monorepo "service" deploys to production in 8 minutes or less via AWS ECS Fargate.
Keeping track of Ramp's MoM service reliability across 400+ services for SLIs → SLOs → contract SLAs (four & half 9s).
Managing isolated, pre-deployment production infrastructure in Buildkite with cryptographically signed builds, enforcing artifact provenance across database migrations, agent registration, and other deployment-critical steps.

Research Interests

I'm interested in the intersection of systems, networking, security, and privacy. In particular, I'm drawn to problems where strong cryptographic or privacy guarantees have to coexist with the performance and operational constraints of real-world systems. My academic learnings has included secure multi-party computation, private computation, high performance networking, multicore systems, and concurrent systems.
