About
Building and protecting business systems since 2011.
Zenisca Inc. is a privately owned software company in Mississauga. We build software, stores, apps and AI, and we look after the servers they run on.
Our story
Since 2011, Zenisca has built web and desktop applications, online stores, mobile apps and integrations for organizations ranging from small businesses to large corporations across Toronto and the GTA.
Our focus has always been secure, scalable and reliable business systems. Today that includes private AI and local model training, alongside the security upgrades, maintenance and backups that keep everything running.
Zenisca is led by a software engineer with more than twenty years of hands-on experience across Swift, Objective-C, C#, PHP, Python, Rust, JavaScript and Node.js. The person who scopes your project understands the code that will deliver it.
