Human building software · 20+ yrs

Hello, I’m Chris. I build apps and interfaces for the web and the pocket — and I try to live well outside the screen too. Running, lifting, reading slowly, staying curious. Twenty years of shipping, longer of paying attention.

About

Full-stack developer by trade, quiet and careful by temperament. I build things for browsers and phones — and the systems that keep them running. Frontend to backend, prototype to production.

Currently leading Wenya, my latest commercial project, and shipping Kalorique™, a calm companion for building healthy habits that stick. Small things on GitHub.

Selected work

Stack

React, Next.js, TypeScript. Node, Express, Prisma, serverless on AWS. MongoDB, DynamoDB, MySQL, Redis. React Native, Expo, SwiftUI. Jest, Vitest, Cypress. Stripe, PayPal. Docker, Jenkins. LLM integrations.

Off the keyboard

Three things keep me honest outside of code. I run — long roads, quiet mornings, the meditative rhythm of laps. I lift — slowly working on the body, because writing code for twenty years takes a toll. And I read, for the pleasure of it. A running inventory of what’s been worth the time lives on /library.

The half marathon is my preferred distance — long enough to mean something, short enough to enjoy. Two behind me, three more on the calendar.

Luck flows through people and travels by conversation. The people you talk to determine the opportunities you find. Keep talking to the same people, keep finding the same opportunities. Start talking to new people, start finding new opportunities. If you want different luck, start walking into different rooms.From the diary
