Flows, component system, key screens.
Week 2 to 4 - 04
Build in slices
Vertical slices shipped to staging weekly.
Week 4 to 12 - 05
Harden and launch
Security review, load check, monitoring, go live.
Final 2 weeks
Common mistakes
- Building version three before version one has a user
- Skipping access control until after launch
- No audit trail on money or medical data
- Designing screens before the data model
- No monitoring, so outages are reported by customers
Our checklist
- Every role's permissions written down and tested
- Data model reviewed before UI work starts
- Automated tests on the paths that cost money
- Errors and performance monitored in production
- Backups and restore tested, not assumed
Custom Web Application Development FAQs
How much does a custom web application cost?
+
Builds start at ₹4,00,000. Scope, integrations, and compliance requirements drive the range.
How long does an MVP take?
+
8 to 16 weeks to a production release. We ship vertical slices weekly so you see progress from week four.
Do you work with our existing developers?
+
Yes. We can lead, pair, or hand over with documentation and a review process.
What about scalability?
+
We choose boring, scalable defaults: typed code, managed databases, edge deployment, and clear boundaries so scaling is a configuration problem, not a rewrite.
Who owns the code?
+
You do. Repositories and infrastructure are in your accounts from day one.
