Web app and SaaS development, from scoped MVP to live product
You have a product idea, an internal process that has outgrown spreadsheets, or a half-built app. We scope the smallest version worth launching, build it in weekly increments you can click through, and hand over a documented codebase in your own GitHub.

Full-stack product development by a senior engineer
We build the whole product: login and roles, database and APIs, the admin panel you'll run it from, payments, analytics and deployment. It suits founders launching a first version and businesses replacing manual workflows with an internal tool.
A good fit if
- You're a founder with a validated idea who needs a working v1, not another deck
- A core process runs on spreadsheets and WhatsApp, and it's starting to break
- A previous build stalled and you need it re-scoped and shipped
- You want progress you can click through every week, not status calls
Probably not a fit if
- You need native App Store or Play Store apps. We build web apps and installable PWAs, and can refer you to React Native partners.
- You want open-ended hourly development without a defined scope. We work to a fixed scope and price.
Why product builds stall
Most failed builds don't fail on technology. They fail on scope, ownership and visibility.
- Version one has forty features and none of them work end to end.
- Sprints keep being added and the budget keeps growing, with nothing live.
- The developer who built it has gone, and nobody else understands the code.
- There's no admin panel, so every change to users or data needs a developer.
- Security was left for later: no roles, no rate limiting, no input validation.
What we build
Everything a real product needs on launch day, not just the screens in the demo.
Scope and architecture
We cut the wish list down to what proves the idea, then plan the data model, API and user flows before writing code.
Login, roles and permissions
Email and social sign-in, roles such as admin, team and customer, and access rules enforced on the server rather than just hidden in the interface.
Database and API
Firebase or Supabase with a clear schema, server-side routes with validation and rate limiting, and error handling that doesn't take the app down.
Admin dashboard
The panel you run the business from: users, content, orders and settings, with search, filters and export.
Payments
Razorpay for India or Stripe internationally, one-time or subscription, with webhook handling for every payment event.
Analytics and monitoring
Product events, marketing tags and error logging from launch day, so you can see how the product is actually used.
How the product fits together
A product is a chain of parts that all have to work for a customer to pay. We build and connect every link.
- Built in this system
- Connected system
- The outcome
Users (built in this system)
Sign-up and login, with roles that decide what each person can see and do.
Product (built in this system)
The core workflow your users came for, server-rendered and fast on mobile.
Payments (built in this system)
Razorpay or Stripe checkout and subscriptions, with every payment event recorded.
Admin (built in this system)
Your team manages users, data and settings without calling a developer.
Growth
Public pages ship with SEO metadata and tracking. A marketing site or funnel around the product is a separate build.
Growth website systemRevenue
Paying customers you can see, count and support.
How the project runs
Fixed scope and price before we start, and a staging link to review before anything goes live.
01
Scope the first version
We agree what v1 must do to prove the idea, and write down what waits for later. You get a fixed scope and quote.
02
Design the architecture
Data model, API routes, login flows and wireframes, reviewed with you before the build begins.
03
Build in weekly increments
A staging link updated every week. You test on your own phone and course-correct early, not at the end.
04
Launch and hand over
Production deployment with monitoring, documentation and a 30-day support window. The repository and accounts are yours.
What you get
Included in the handover, agreed in writing before we start.
- A deployed web application on your own Vercel account
- Authentication with role-based access
- A database schema with validated, rate-limited API routes
- An admin dashboard for users, data and settings
- Razorpay or Stripe payments with webhook handling, where needed
- Analytics events and error logging from launch day
- A documented codebase in your GitHub: setup guide, architecture notes, environment reference
- 30 days of post-launch support

Frequently asked questions
Straight answers about our SaaS / Web App Development. If yours isn't here, ask us directly.
Ask on WhatsAppWhat tech stack do you use?
Next.js with TypeScript on the frontend, Firebase or Supabase on the backend depending on the product, Razorpay or Stripe for payments, Tailwind CSS for styling and Vercel for hosting. We choose what suits the product, not what's fashionable.
How much does a product build cost?
MVPs typically range from ₹80K to ₹1.5L, covering login, core features, an admin dashboard and deployment. Fuller products with payment flows, advanced dashboards, multiple roles and integrations range from ₹1.5L to ₹4L. You get a fixed quote with a detailed scope before we start.
Can it scale later?
Yes. Firestore and Supabase handle large data volumes, Vercel scales serverless functions automatically, and the API routes are validated and rate-limited from the start. The codebase is organised so new features can be added without a rewrite.
Do you build mobile apps?
We build web applications. If you need a mobile-first experience, we build progressive web apps (PWAs) that install on the home screen on iOS and Android. For native App Store or Play Store apps, we can recommend React Native partners.
What if I don't have designs or wireframes?
Most founders we work with don't. We start with a scope call, create the wireframes and flows ourselves, and you approve them before any code is written. If you already have Figma designs, we build from those.
How is this different from hiring a full-time developer?
A full-time developer still needs product direction, design and deployment set up around them. We cover product thinking, architecture, frontend, backend, deployment and documentation for a fixed project fee. After handover, you can hire in-house to maintain and extend it.
What happens if I need changes after launch?
The 30-day support window covers bug fixes and small changes. After that, ongoing development on a monthly retainer is optional. The codebase is yours, and the documentation is written so any Next.js developer can continue the work.
Can I see products you've built?
Yes. The MetroMitti and TDSS case studies cover a real estate marketplace and a certification CRM. Our own consultation booking system at /book is another product we built and run.
Scope your first version with us
