Driving Change in Tech
Women in Tech Toronto
Hosted by Criteo

In-Person Event
Toronto, Canada
Join us for a new WomenTech Network in-person event in Toronto, organized by Criteo, a space designed to share knowledge, connect, and empower women across the tech community.
The event’s keynote will focus on how to deal with legacy systems based on a real-world experience rearchitecting a tightly coupled monolith through incremental delivery. Modernizing a legacy system is more than a technical challenge. We’ll look at how to use vertical slices to reduce risk while continuing to ship value.
The event will also feature a panel discussion on how individuals across different roles drive change at work, from influencing teams and leadership, to turning ideas into meaningful impact.
