Chris Witko
Fullstack developer · 20+ yrs

Hello, I’m Chris. Full-stack developer with 20+ years of practice — apps and interfaces for the browser and the pocket. Always shipping.

About

A passionate full-stack developer dedicated to continuous learning and quiet, careful work. I build apps and interfaces for web and mobile — and the systems that keep them running. Frontend to backend, browser to pocket, 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.

Running

Outside of code, I run. Long roads, quiet mornings, the meditative rhythm of laps. The half marathon is my preferred distance — long enough to mean something, short enough to enjoy.

No matter how busy you are, you must take time to make the other person feel important. Everyone has an invisible sign hanging from their neck saying, "Make me feel important." Never forget this message when working with people.From the diary
