Our Work
Custom Web App Projects That Moved The NumbersCalibre Web Studio works with startups and growing teams that need more than a pretty interface. Our custom web app development for startups focuses on products that have to handle real traffic, real customers, and real operations.
Every project starts from a clear business goal, not just a list of features. We design, build, and ship on React and Django so your product stays fast, secure, and understandable as you grow.
SaaS analytics platform for product teams
A B2B startup needed a way to track feature usage across multiple customer accounts. We designed and built a multi tenant SaaS product with role based access, usage dashboards and clean APIs. The result was faster onboarding, clearer activation insight and a product they could confidently demo to investors.
MVP for a workflow automation startup
A founder came to us with a deck and a rough idea. Together we defined a focused MVP that automated one core workflow instead of six. We shipped a production ready version in eight weeks with tracking and error logging in place. That first release helped them secure initial customers and a follow-up funding round.
Custom portal for operations and support teams
A growing company was running daily work from spreadsheets and email. We replaced that with a custom web app that centralised requests, files, and status updates. Support tickets went down, response times improved, and managers finally had a real-time view of workload without manual reports.
Checkout and performance rebuild for an online store
An eCommerce brand was losing customers to slow pages and a confusing checkout. We rebuilt key flows on a modern stack, simplified the journey, and tuned performance. Page load times dropped, completed orders increased, and support stopped hearing about failed checkouts.
For each project, we look at:
- Performance improvements, such as load time and error rates.
- Product metrics such as activation, churn, and conversion.
- Operational outcomes such as fewer manual steps or support tickets.
