Based in Abuja. Working with New York teams since 2020.
Senior software engineer at Parallel
I’m Precious Origho. I build features that power events for global brands and AI tools that help engineering teams ship safely.
Side project
Most of my professional work is private, so Walk n Sit is the project I can share. It reminds you when to stand, walk, and sit, and records activity with Apple Health.
Mobile / health
01Walk n Sit helps people break up long periods of sitting with simple reminders to stand, walk, and sit. It can also save walks and workouts to Apple Health.
What made it tricky
Timers and reminders still need to behave when the app is backgrounded, interrupted, or reopened later.
About me
I started at Parallel as an intern and grew into a senior engineer. Today I work across Node.js and Postgres, Next.js, and React Native. I write design docs, build features, review code, help teammates, and stay close to what happens after release.
At Parallel Studio, part of Parallel, I’m a technical anchor on Rumor’s event platform, building features that power events for brands including McLaren, Billboard, and Revolve. I also built a 51-tool MCP server that gives coding agents project context, contract checks, and verification before they finish work.

Get in touch
I’m always happy to talk about product engineering, developer tools, or a problem that could use a second set of eyes.
