Hi, I'm Parish. I build web products founders can rely on.
Building for the web since 2013, from the frontend of a platform serving millions to full SaaS products I have shipped solo. I care about speed, clean code, and interfaces people enjoy using.

How I think about the work
- Principle 1
Tests come with the feature, not after the bug report.
- Principle 2
Reusable design systems beat one-off components, even when nobody's asked yet.
- Principle 3
Page weight is a feature you can't add later.
- Principle 4
Big migrations should be invisible to customers.

What people say
Parish is, hands down, one of the best React developers I've worked with. He took our design system from fragmented components to a cohesive, well-tested library that the whole team now relies on.
Delivered a complex e-commerce platform 2 weeks ahead of schedule. Clean code, excellent communication, and zero post-launch bugs. Will hire again.
Parish doesn't just write code. He thinks about the user, the team, and the long-term maintainability. A rare combination of speed and quality.
Let's build something that lasts.
