Hi, I'm Jana 👋
I design & build websites, web apps & mobile apps that help your business grow.
// About
I'm a senior software engineer, freelancer, and entrepreneur based in Toronto, Canada. For over a decade I've turned ideas into robust, polished software — from fast marketing sites to real-time apps and large-scale platforms — and I love building things people genuinely enjoy using.
By day, I'm a Senior Software Engineer at the University of Toronto Libraries, building and maintaining applications that serve thousands of researchers. By night, I run Codepiercer, where I help clients bring ideas to life — personal and business websites, landing pages and showcases, custom web apps with real-time features, and cross-platform mobile apps for iOS and Android.
I work with you end-to-end — thoughtful design, solid engineering, and reliable, hassle-free hosting — so you get something fast, dependable, and built to last. Have a project in mind? I'd love to hear about it.

Bespoke, full-stack tools built exactly to your workflow — from MVP to production-ready product.
Mobile Apps (iOS & Android)
Cross-platform mobile apps for iOS and Android, from concept to the App Store and Google Play.
…and everything in between. If you can imagine it, I can build it.
