Web apps built to survive real users.
We design and ship custom web applications — dashboards, portals, internal tools and SaaS products — on a modern TypeScript stack. The focus is getting a working product in front of real users quickly, then hardening it: proper auth, sensible data modelling, and tests where they actually matter.

Why teams call us.
Your process lives in spreadsheets
Manual workflows across shared sheets break as soon as more than three people touch them. A purpose-built tool removes the coordination tax.
The MVP quote came back at six figures
Most MVPs are over-scoped. We cut to the one workflow that proves the product, ship that, and expand from evidence rather than assumption.
You inherited a codebase nobody understands
We audit, document and stabilise existing applications, including taking over stalled builds from a previous agency.
Everything included
as standard.
No tiering the basics. These ship with every web app development engagement regardless of package size.
- Technical discovery and scoped architecture document
- Database schema design and migrations
- Authentication, authorisation and role management
- REST or tRPC API with typed contracts
- Responsive application UI built on a design system
- Third-party integrations: payments, email, storage, CRM
- CI/CD pipeline and staging environment
- Handover documentation and code walkthrough
How a web app development
project runs.
Discovery call
We map the core workflow, the users and the constraint that actually matters. 30 minutes.
Technical scope
Architecture, data model, integration list and a milestone plan with fixed deliverables.
Design + prototype
Clickable prototype of the core flow so you can react to something real before we build it.
Build in sprints
Two-week sprints with a working staging deploy at the end of each one. Progress is continuously visible.
Harden and launch
Load testing, security review, monitoring, then production deploy and handover.
Web App Development packages.
Ranges, not fixed quotes — final scope lands on the discovery call. Every package books straight into the calendar.

Straight answers.
What stack do you build web apps in?
TypeScript throughout. Typically React or Next.js on the front end, Node with a typed API layer on the back end, and PostgreSQL for data. We choose boring, well-supported tools you can hire for later.
Can you take over an existing project?
Yes. We start with a paid audit that documents the current architecture, flags the real risks and gives you a stabilisation plan. You keep that document whether or not you continue with us.
Who owns the code?
You do, from the first commit. Work happens in your repository under your organisation, and infrastructure runs on accounts you control. There is no vendor lock-in.
How do you handle changes mid-project?
Each sprint has a fixed scope agreed in advance. Changes go into the next sprint rather than silently expanding the current one, so timelines and budget stay predictable.
How much does it cost to build a web app in India?
A focused MVP with one core workflow starts around 1,50,000 rupees. A multi-role platform with billing and integrations typically runs 4,00,000 to 8,00,000 rupees. You get a fixed milestone quote after technical scoping.
