Overview#
Violerts is a property-compliance SaaS platform for New York City real estate professionals. It brings together information that is normally scattered across many separate sources into a single, easy-to-use view, so owners, managers and their teams can understand the compliance status of a property and act quickly.
The challenge#
When I joined, the product was an early-stage MVP. It worked, but it needed to become a dependable, commercially viable SaaS product: broader coverage, a more reliable and faster experience, better ways to stay informed, and a model that supports teams rather than just individual users.
My role#
As Lead Full-Stack Software Engineer, I worked across the whole product rather than a single layer. I was responsible for modernizing the application end to end and for turning it from a basic lookup tool into a platform that businesses can rely on every day.
What changed#
Broader coverage#
The platform expanded significantly in the amount and variety of property information it provides, giving users a much more complete picture from a single place.
A faster, more reliable experience#
I improved the reliability and responsiveness of the product so that heavy workloads no longer get in the way of day-to-day use, and users see a noticeably quicker interface.
Visual, map-based exploration#
Property information is now presented visually and in context, instead of only in tables, which makes research and due diligence faster.
Timely alerts#
Users can be notified promptly when something important changes, so they no longer depend on manual checking.
Built for teams and businesses#
The product now supports organizations, multiple team members and shared collaboration, which opened it up to larger property-management and professional teams.
Subscription model#
I built the commercial foundation of the product, including flexible plans and access levels, so the platform can grow as a recurring-revenue SaaS business.
Results#
Violerts evolved from a basic property lookup application into a broader compliance platform used by real estate professionals. The work delivered wider coverage, a faster and more dependable experience, timely alerts, team collaboration and a scalable subscription model, backed by more than 1,180 production commits across the stack.
