Daniel Onyesoh

I am a backend engineer with deep Rust expertise and strong experience building data-intensive systems in production.

At Mixrank I built performant, high-throughput data pipelines to generate insights from petabyte-scale PostgreSQL databases, and I’ve contributed core backend work and tooling for remote projects.

I co-founded Certify, wrote its backend on the Internet Computer Protocol, and helped craft the business plan and pitch that won our team first place at a hackathon.

I’m also a language-and-tooling contributor: I helped design the Helios language, authored its documentation and specification, and built related tooling. I enjoy solving systems problems, designing reliable APIs, and delivering well-tested, documented software.
