Building the WeekPlan Productivity Platform at Scale
WeekPlan helps tens of thousands of professionals prioritise their most important work using a framework inspired by the 7 Habits and OKR methodology. We helped evolve the platform from its origins to a modern, scalable React and AWS-powered product.
Overview
WeekPlan is a productivity tool built around a deceptively simple premise: if you can identify your most important priorities for the week and schedule them deliberately, you will achieve more of what actually matters. The platform draws on Stephen Covey's 7 Habits of Highly Effective People and OKR goal-setting methodology to help users move from reactive task management to proactive, roles-based planning. By the time Skybin joined the project, WeekPlan had already built a meaningful user base — but the original technology stack was beginning to constrain the team's ability to ship features, handle load, and maintain a competitive user experience. The platform needed to grow up technically without losing the simplicity that made it valuable.
The Challenges
Frontend Stack Showing Its Age
The original frontend was built on KnockoutJS — a capable framework at the time, but increasingly difficult to extend, test, and hire for as the React ecosystem matured. New features were slow to develop, and the component architecture made it hard to maintain consistency across the growing interface.
API Layer Not Built for Scale
The ASP.NET Web API powering the backend had grown organically without a strong design contract. As the user base grew, performance under load became a concern, and the lack of consistent API patterns made it harder for the frontend team to work confidently against it.
Infrastructure Not Keeping Pace with Growth
The platform's infrastructure was not designed for the elastic scaling demands of a SaaS product with an internationally distributed user base. Capacity planning was manual, and the deployment process was not aligned with the rapid iteration cadence the product team wanted.
Our Solution
Incremental React Migration
Rather than a risky big-bang rewrite, we adopted an incremental migration strategy — introducing React component by component alongside the existing KnockoutJS code, allowing new features to be built in React while legacy screens were gradually replaced. The product remained fully functional and shipping throughout.
API Modernisation & Performance Work
We audited the existing ASP.NET Web API, identified the highest-impact performance bottlenecks, and established consistent API design patterns going forward. Key endpoints were optimised, caching was introduced where appropriate, and API documentation was formalised to improve the frontend development experience.
AWS Infrastructure & Deployment Automation
We migrated the platform to a properly architected AWS environment — using Elastic Beanstalk for the application layer, RDS for managed database hosting, and CloudFront for global content delivery. Deployment was automated, enabling the team to ship confidently and frequently.
Results & Outcomes
Modern, Maintainable Frontend
The React migration gave the team a component library they could build on confidently, with a dramatically improved developer experience compared to the legacy KnockoutJS codebase.
Improved API Performance Under Load
Targeted performance work and consistent API patterns reduced response times for the most-used endpoints and gave the frontend team a reliable surface to build against.
Scalable AWS Infrastructure
The platform now scales elastically with demand, with no manual capacity management required. Deployments that previously required coordination and risk management became routine, automated events.
Faster Feature Delivery
With a modern frontend stack, a clean API, and automated deployment, the team's cycle time for new features dropped significantly — letting the product compete effectively in a fast-moving market.
Conclusion
WeekPlan now runs on infrastructure and a codebase that can grow with the product. The incremental approach — migrating the frontend, modernising the API, and rearchitecting the infrastructure — delivered a step-change in the team's ability to ship without the disruption of a full rebuild. The platform's users experienced continuity; the engineering team gained a foundation they could build on for years.
