Web & App Development
Custom Web Applications
Powerful, enterprise-grade web applications tailored to your specific needs.
Overview
From multi-role CRM dashboards to internal tools and customer portals — fully customised, typed and scalable applications on a stack you own.
Off-the-shelf SaaS tools solve 80% of the problem and charge you forever for the 20% that doesn't fit. MIRVEX builds the application that solves your exact problem — a multi-tenant CRM, a field-force tracking portal, a financial reporting dashboard, or an internal operations tool. We architect for the load you have today and the scale you'll need in two years. Role-based access control, audit logs, real-time notifications, CSV export, and API integration with third-party services come standard. Every application is typed (TypeScript), tested, and documented so your team can maintain and extend it without calling us every time.

How we work
A process built to de-risk every launch
Five deliberate stages — so you always know what’s happening, what’s next, and why.
Design
Wireframes to high-fidelity systems. Every screen is designed for clarity, conversion and accessibility before a line of code ships.
Build
Production-grade engineering in weekly increments. Typed, tested and reviewed code on a modern, scalable stack you actually own.
Launch
Hardened deploys, analytics, SEO and performance budgets dialed in. We ship with monitoring so launch day is a non-event.
Scale
Roadmapped iteration, proactive maintenance and a 24/7 support line. Your software keeps compounding long after go-live.
