Tired of budget blowouts, delays and broken promises?

You’ve seen it happen. Projects that were supposed to take 3 months stretch to 8. Budgets balloon. Developers disappear after launch, leaving you with code no one understands.

It doesn’t have to be this way.

Why clients trust
Top Base

As a senior product manager, I have worked with a handful of vendors, consultant agencies and development shops. I am confident to say that Top Base is among the best considering the velocity, quality of the work and the overall ROI. The team took ownership, overcame a steep learning curve in a new industry, and delivered promises. We are very thankful for the dedication of the team and would recommend Top Base to any company, large or small, to help with your technical project.

Case study: Transforming media operations for speed & savings

Client: Numeris | Industry: Media & broadcasting

The challenge: Numeris was operating a business-critical, client-facing platform on an outdated Drupal system. Performance was slow, workflows were manual, and the rigid architecture limited their ability to innovate. Teams were stuck in inefficient processes, and clients faced delays accessing reports and insights, impacting satisfaction and productivity.

Our Solution: We rebuilt the platform as a custom web application, using a Laravel 9 backend and Vue.js frontend to deliver a more scalable, maintainable, and performant architecture. We implemented a modern, API-first structure, integrated third-party tools, and introduced an intelligent, keyword-based search experience to streamline report discovery and user navigation.

The Results:

  • Reduced projected development costs by 75%
  • Significantly improved app speed and workflow efficiency
  • Enabled faster report access through smart search
  • Delivered a cleaner, more modern user experience

Case study: Scaling a startup into a national contractor marketplace

Client: QuickContractors.com | Industry: Construction & service marketplace

The challenge: Back in 2005, QuickContractors.com set out to digitally connect homeowners with reliable contractors. Their early platform, built in Classic ASP, was designed for simple service requests and scheduling. As the company grew, securing partnerships with Home Depot, Lowe’s, and other major retailers. The legacy system couldn’t keep up with the demand for logistics, dispatching, and real-time coordination.

Our Solution: We migrated the system from Classic ASP to ASP.NET, modernised the architecture, and scaled the infrastructure to Microsoft Azure Cloud. We introduced advanced features like contractor dashboards, mapping tools, and dispatch automation, ultimately building a full-fledged Contractor Management System tailored to national-scale operations.

The Results:

  • Scaled from 1 developer to 50+
  • Supports thousands of contractor-homeowner connections
  • Acquired by one of Canada’s largest corporations
  • Continues to deliver a seamless user experience nationwide

Case study: Stabilising and scaling a real estate platform without a rebuild

Client: RenterVibe | Industry: Real Estate

The challenge: RenterVibe’s custom platform, built on PHP and jQuery, was buckling under technical debt. The codebase was brittle, the database poorly structured, and the platform lacked the flexibility needed to integrate new features or scale. A full rebuild wasn’t an option due to budget constraints, yet stability and growth were essential.

Our Solution: We stabilised the existing system through targeted backend optimisations and code refactoring, restoring platform reliability without a full rewrite. We then integrated essential third-party services in finance and real estate, introduced new in-app features, and laid the groundwork for gradual scaling. All while preserving the legacy structure and minimising disruption.

The Results:

  • Achieved 99%+ uptime
  • Launched new product lines without rewriting the app
  • Enabled real estate and finance integrations
  • Improved user confidence and platform adoption
